  • What do I do with my Lithium batteries when the weather is cold?
    Cold Weather Maintenance You can discharge (take energy out) of the batteries down to a battery core temperature of -4 degrees F. You can recharge lithium batteries when the core temp of the battery is 32 degrees F or warmer (41 degrees or warmer for Victron batteries. Victron is listed in C, this is 5 Degrees C) If your batteries have heaters, do not leave the heaters on all night unless you are plugged into shore power, as you will use unneeded energy. If your batteries have heaters, but there is no way to charge (not plugged into shore power, no generator available, solar panels are covered in snow), turn your heaters off. If you do not have heaters, your batteries MUST be warmer then 32 degrees F to charge (41 degrees for Victron). Some battery heater installations do not feature a switch for remote operation. If that is the case, your heaters will turn on and off automatically as temperatures demand. Please keep an eye on your battery state of charge. If you are not using your trailer / RV etc. for the winter, ensure your batteries are above 80% state of charge, and disconnect the master Negative cable from the batteries. If you have Battle Born heated batteries (BB12100H) disconnect the “heat enabled” wire from the small red button terminal located right beside the positive terminal. Many customers have main disconnect switches that will cut the power to the batteries, but you should take extra care that they are TRULY disconnected. Often RVs will still have a C02 sensor, backlit stereo, or some other emergency sensor that is bypassing this switch. If you are in doubt, simply disconnect the main positive and negative wires that supply your batteries. After the winter storage time, you should have plenty of charge in the batteries. With LiFePO4 batteries, we recommend disconnecting all potential power draws from the battery and letting them sit with a full charge, or at least a 50% charge minimum. On a full charge, LiFePO4 batteries have been proven to last at least a year in proper storage conditions with a 2–3% depletion each month. If left at a half charge, the batteries have the potential to not last as long in storage. Tests indicate that at 0 degrees Fahrenheit, with no insulation, the Battle Born internal heater is on about 30% of the time. With no external charging or loads, it gives approximately 185 hours (7 days) of heat capability before the battery goes into a low voltage disconnect. If the batteries are stored without a charge, their levels could dip below what the internal Battery Management System, or BMS, can protect over the winter season. If possible, we recommend storing them fully charged in an environment above freezing. Our team recommends not leaving a completely drained battery in that state for an extended amount of time, as it can damage the cells inside. Doing so will void the warranty! If you do find yourself with batteries that are too cold to charge, you have a couple of options: Bring the batteries into a warm space or park your vehicle indoors Run a space heater (use caution) inside your vehicle to warm the batteries up. DO NOT use power from the batteries ie. Your inverter, to power the heater. Run an extension cord from your house to the vehicle and plug the heater into your home. If your batteries are above 60% state of charge, and you can confirm there is no load on the batteries (verify though your shunted meter, you should see 0.0A / 0W load), you can safely leave your batteries for 90 days without worry. LEAVING A LITHIUM BATTERY IN A FULLY DISCHARGED STATE WILL VOID YOUR WARRANTY!!!! When in doubt, remove your batteries and bring them into us to be fully charged and ready for storage. This will take 24-48 hours. TAKE PICTURES OF YOUR SYSTEM BEFORE DISCONNECTING ANY WIRING. We are not liable, nor can we assist with “I forgot where this wire goes”. That is your responsibility.

Questions should first be submitted through email to When contacting us for technical assistance, please describe your issues as thoroughly as possible, and include any relevant information to help us better assist you. As distributors for the brands we sell, we do not have any greater access to information other than to carefully read and understand the product manuals. This means you have access to all of the information and troubleshooting procedures, by reading and understanding your product manuals. We will not provide support for any product line we do not sell. If you have questions about a product you did not purchase through us, please contact your original seller, and if that fails, contact the manufacturer. Please have your invoice and/or sales receipt number ready when contacting us for product support. When selling your rig with a system installed by Bend Battery, there is a mandatory 2 hour “New Owner Consultation” you must tell the new owner is required. In some cases when our installs go out of state, client’s have other companies add extra accessories or reconfigure in which case we cannot guarantee the work was done correctly or to the standards we uphold. In many cases, these other companies are not equipped or knowledgeable enough to perform work on a complex system without causing damage or reducing/severing functionality of your system. The system must be returned to us to verify functionality before any other technical support is available. Bend Battery is not liable for damages or the inability for your system to function appropriately due to the work performed by another company. Victron Connect App: The Victron Connect App is the most useful tool you have to monitor and interface with your system. Victron Connect is a free App that does not require cell service to work with your system. This means that even in the most remote areas with no service, you will still be able to monitor your system. To download the app, go to your smart phone’s App Store/Google Play and search for “Victron Connect”. Once you have found it, download the application (you do need cell service or internet connection to download the app). Allow all permissions the app requests. Once downloaded, open Victron Connect and go through the provided tutorials. Please remember, Victron Connect communicates to your products via Bluetooth. This means you must be within range (20ft ± depending on your phone or tablet and location of products) and Bluetooth must be “ON” on your device. Once opened, Victron Connect will automatically populate the products that are within range and able to be viewed via the app. Select the product you are interested in viewing. Once selected, the product will ask for a PIN code. The default PIN code for ALL products is “000000” Six zeros. Once the product has loaded, it will pop up a dialog box prompting you to change your PIN. We do not recommend changing your PIN number. If forgotten, it can be a challenge to reset it. If you do not wish to change your PIN or re-enable it each time you want to view your device, check the box that comes up with the initial dialog box, then select “Not Now”. That product will not ask you for a PIN number again. Repeat this process with all of your products on the Victron Connect App. Victron Connect / Forgot Your Password: If you changed your password and have forgotten it, you will need to reset the password. First, physically locate the product you forgot the password for. On the product itself, there will be a white sticker/tag. On that tag will be the product number, serial number, and the PUK code. Locate and write down your PUK code. Next, open the Victron Connect App and locate the product you need to reset. On the right side of the product there will be a triple dot (Three dots stacked vertically), click the triple dot and select “reset password”. On the next screen you will enter the PUK code. Doing so will revert the PIN code to the factory default of “000000”, six zeros. Keep in mind the white tag may be hard to access, or even on the bottom mounting surface of the product (requiring you to uninstall the product to access the tag), for this reason, we recommend you do not change your password and forget it. If you cannot access the PUK code and have to bring your system to us for the reset, you will be charged the current labor rate for the time used. Battery Types: Wet Filled/Flooded Cell – Lead Acid Batteries This type of battery is commonly used in vehicle starting, and budget deep cycle batteries. Most 6 volt Golf Cart sized batteries are flooded cell batteries. You can commonly identify a wet fill battery by the service/water caps location on the top of the battery. Below are some common questions and technical support requests related to flooded cell lead acid batteries. Q: Do I need to keep my battery charged? A: YES! You must store a lead acid battery at 100% state of charge, and maintain that state of charge throughout storage. Failure to do so will void your warranty! Q: What voltage should my battery be at? A: 12.56v+ = 100% State of Charge (SOC). 10.6v = 0% State of Charge (SOC) Any voltage of 12.0v or less will damage your battery and void your warranty. Q: How much power can I use from my battery? A: With ALL lead acid batteries, you can only use 50% of the battery’s stated capacity. Example: You have a 100Ah lead acid battery, you can only use 50% or 50Ah of that. Excessive discharge deeper than 50% SOC will void your warranty. Q: How do I check and maintain my wet filled battery? A: Please follow these steps listed below – -Check the battery voltage. If less than 8v- DO NOT CHARGE! Discard / replace or seek professional assistance. -Check the fluid level of the battery cells (wet filled only, does not apply to AGM batteries), If the fluid level is below the cells and the plates are visible, add just enough distilled water to cover the plates and wait 10 minutes. After 10 minutes, if more distilled water is needed, add just enough to cover the plates and re-check after another 10 minutes. Once the fluid level is above the plates and stable, proceed to the next step. - Fully charge the battery using an automatic battery charger. Failure to use an appropriate charge and voltages could lead to a battery explosion. Use caution when charging. If the battery gets excessively warm during the charging process, unplug the charger from the wall outlet, wait 10+ minutes, disconnect the charger from the battery and seek a replacement battery. - Once your battery is fully charged, you will need to “top-off” your fluid levels. After the battery is charged, add distilled water to each cell to bring the fluid level to 1/8”-1/6” below the bottom of the “fill well.” Do not overfill! Q: Is there anything else I should do for my wet-filled battery? A: Yes. Anytime you see corrosion you will need to clean it. Corrosion typically builds up on battery terminals, cables, battery hold downs and battery trays. You can use battery specific cleaners or baking soda and water. A wire brush should be used in conjunction with a cleaner. AGM of Absorbed Glass Matt battery This type of battery is completely sealed and does not have any free flowing acid inside of it. Wet fill/flooded and AGM batteries are both Lead Acid batteries, and therefore are both subject to the same limits and care. The exception to this is maintenance. AGM batteries have no free flowing acid and do not need fluid level checks or water addition. All other rules and limitations of a lead acid battery apply. LiFeP04/Lithium batteries Lithium batteries are the answer to the most common battery complaints and care requirements. This type of battery is used for deep cycle applications. You can identify a lithium battery in a couple different ways. First, the battery should be clearly labeled “LiFeP04”, “Lithium Iron Phosphate,” or “Lithium.” The second way of identifying a lithium is by its weight. Where an average 100Ah lead acid battery weighs around 70lbs, a lithium battery will weigh roughly half that, or 30lbs. Do not rely on weight alone, but rather a clue. LIFeP04 and lithium will be used interchangeably in this manual. Lithium batteries have several advantages over other types and only a couple of use considerations. Q: Do I need to keep my battery charged? A:Lithium batteries can be stored at a partial state of charge (less than 100% SOC). So long as the battery does not become completely discharged, no damage or loss of performance will occur. Q: Where should my battery voltage be?? A: A lithium battery’s voltage will not fluctuate much throughout its range of use. Because of this, a shunted meter should always be used with a lithium battery. Using voltage with a lithium battery is difficult, but there are a couple of key voltage points. 13.6v+ your battery is close to or fully charged. 13.1v your battery is close to or is at 50% SOC +-25% 11v your battery is almost completely discharged. All voltage must be taken with the battery at “rest.” “Rest” = no energy in or out of the battery for 30 minutes. Q: How much power can I use from my battery? A: You can use 100% of your battery’s stated capacity. However, we recommend not going below 10% SOC to avoid any complications. If you fully discharge your battery, the BMS (Battery management System), will disconnect the cells or “Turn off” the battery to prevent damage to the cells. At this point your voltage will be 0v or close to it. You must charge your battery within one week of a low voltage disconnect event. Failure to do so will VOID YOUR WARRANTY! To turn your battery back on, you can use a few different methods. 1) Use a charger that will charge a low voltage battery or has a lithium setting. We prefer the Victron Energy Blue Smart IP65 series of chargers. 2) You can use a “Jump box” that you would typically use to jump a vehicle. We prefer the NOCO series of jump boxes, such as the GBX70 3) If you have a solar system with a Victron Energy charge controller, the solar will typically be able to turn on your battery. 4) Use a power supply or charge that has a power supply mode, such as a NOCO G7200. Voltage should be set to 13.6v and Amps less than 5a. *** When in doubt, seek advice from the manufacturer. Q: How do I check and maintain my lithium battery? A: There is no regular maintenance needed for a lithium battery. Your only obligations are to ensure the battery always has at least 20% SOC during storage, and is never stored in a fully discharged state. Q: What about the temperature's effect on my lithium battery? A: With a lithium battery, you can take energy out of the battery (discharge) down to a battery core temp of -4 degrees Fahrenheit. This means at -3 degrees Fahrenheit your lights, heater, pumps etc. Will operate. Once the battery gets to -5 degrees Fahrenheit, the BMS of the battery will “Turn the battery off.” You can put energy into (charge) your lithium battery at a core temperature of 32 degrees Fahrenheit or warmer. At any temperature below 32 degrees Fahrenheit, the battery’s BMS will disconnect the charge circuit inside the battery and your battery will not accept a charge. *** If you have a Victron Energy LiFeP04, the charge temperature threshold is 41 degrees Fahrenheit or 5 degrees Celsius. This setting can be altered, altering this setting in any way will VOID YOUR WARRANTY! *** If you camp or use your vehicle in cold weather you should either purchase a heated lithium battery or external heating pads for your batteries. Battery Monitor With any type of battery, a shunted meter should be used to determine battery state of charge. Bend Battery only sells and supports meters made by Victron Energy. Victron Energy BMV-712 This meter is Bluetooth and features a physical meter face. Victron Energy SmartShunt This meter is Bluetooth only. You must use a phone or tablet to view the information. Do not change any settings on your meter unless directed to do so by a technician. If your shunted meter ever presents a reading of “- -“ where the battery percentage usually displays, that means your shunt has lost calibration. This will occur if your batteries are discharged completely or you disconnect power to your system. To get your meter to read correctly all you need to do is fully charge your batteries. Once the batteries reach a full state of charge, the meter will automatically synchronize and “100%” will be displayed. Your batteries must reach 100% state of charge for the shunt to synchronize. We recommend plugging into shore power for the quickest results. The process of fully charging your batteries and synchronizing your shunt can take up to 2 days or more if you have a larger system. Solar Panels Your solar system (if equipped) consists of one or more solar panels wired together to make an array. There is very little maintenance that needs to be done with your solar panels. To Clean: To clean your solar panels, use only water and a soft towel, like a microfiber. Clean your panels monthly, or as needed. Avoid cleaning your panels in direct sun or extremely hot temperatures, as this can leave water spots. If you have sap on your panels, avoid heavy cleaners and chemicals. Instead, place an ice cube on the sap spot and wait for the sap to be cold enough to be “picked off”. Clean normally after sap has been removed. Performance: Solar panels work by converting the sun's rays into energy and can be stored for later use. Many factors can and will impact your solar system’s performance. Location, time of year, time of day, weather, humidity, pollution, pollen ect. will all impact how much energy your solar panels will output. If you notice low performance from your panels, you should first check to see if they are clean and free of obstructions. Even the smallest amount of shade being cast onto a single panel in the array can have a large impact. Ensure your panels, all of them, are in full and direct sunlight. Solar Charge Controller Your solar system is equipped with a Victron Energy MPPT Smart Solar charge controller. The performance of your solar array can be viewed in the “Victron Connect” app. The Victron Energy solar charge controllers are very reliable, but there is one question with three possible answers we see most often. Q: My solar charge controller shows “0w” being produced. A1: It is night time. I wish I didn’t have to include this, but it is a situation we run into weekly. Your solar system will not produce energy during the night time. A2: Your batteries are fully charged. The charge controller, via the app, will only show you the power it is currently sending to the batteries. If the batteries are fully charged, the output will read “0w”. If this is the case, your charge controller should be in “Float” state. To confirm, turn on some loads such as lights, fan, radio etc, the solar system should turn on to replace the energy being taken out of your batteries. NOTE: This condition most commonly occurs while plugged into shore power and the batteries are being continuously charged. A3: The solar charge controller turned off due to low temperature cut off. This only applies to systems with lithium batteries. To confirm, view the charge controller in the Victron Connect App. On the main landing page titled “Status,” the temperature of the charge controller will be displayed. If the temperature is reported as 32 degrees Fahrenheit (or 5 degree Celsius), the controller has likely turned off to protect your lithium batteries. The charge controller uses an internal temperature sensor to determine temperature. The charge controller does not know the temperature of your batteries, it only knows the temperature of itself. Therefore, if your charge controller and batteries are in different compartments or locations, temperature cut off should be disabled. We have found firmware updates to turn this setting back on. If you feel your charge controller has turned off due to low temp when low temperature conditions are not present make the following changes: - Open Victron Connect App and select your charge controller - Click the gear wheel in the upper right corner - Select “Battery” from the list options - At the bottom of the “Battery” page, turn off “Low Temp Cut Off” Orion DC to DC Charging If your system is equipped with an Orion DC to DC charger, this means your house batteries will charge from your alternator while the engine is running. Your Orion Charge is fully automatic, with no input from you needed. NOTE: The Orion is Bluetooth capable. To view via the Victron Connect App, “Input” voltage must be present on the Orion. This means if you have a trailer or 5th wheel, you must be plugged into your tow vehicle. The plug will be separate from your standard 7-way trailer plug. If you have a van, RV or other vehicle with its own engine, the Orion should always be visible in the Victron Connect App. You may or may not have DC to DC charging in your system. To reduce fuel consumption and wear and tear on your alternator, we program Orion chargers to only charge your house batteries to approximately 95% state of charge. Cerbo GX & Touch 50/70 If your system is equipped with a Cerbo GX and Touch 50/70 interface, congratulations! You have one of the most in depth and reliable system interfaces available. This combination is installed and fully programmed by Bend Battery prior to delivery. There are no modifications you as an end user should perform with the exception of two items. 1) Connection to Wi-Fi. You should connect your Cerbo GX to Wi-Fi any opportunity you get. To connect to Wi-Fi, simply go to the menu, then settings, then Wi-Fi. Find your available network and enter the password. 2) Setting up your VRM account. Your Cerbo GX features VRM, Victron Remote Monitoring. You must be hooked up to the internet in order for data to upload. See your user manual for further information on the Cerbo GX, Touch Screen interface, or VRM. Inverter There are two types of Inverter installations we complete at Bend Battery. Stand alone and system integrated. Stand Alone: This type of inverter requires you plug in the AC device you are trying to power directly into the inverter. Because of the constraints of this type of installation, we do not commonly install inverters in this fashion. Victron Energy brand inverters are the only stand alone inverters we sell, install or give technical advice on. These units are available from 250VA-1200VA power outputs. Because of their limited power output and use limitations, these are commonly reserved for small systems or specific requests like to power a c-pap machine. The Phoenix series of inverters are incredibly easy to use, simply turn it on and plug in the device you are going to use. The available power from your inverter depends on what model you have installed. Always check that the load you are powering is within the specifications of your inverter. Attempting to run a device that requires more power than your inverter can supply could cause an overload condition. To clear an overload condition, unplug the device that caused it, turn the inverter off, wait up to 5 minutes, then turn the inverter back on. Remember to ALWAYS turn your inverter off when not in use. The inverter simply being turned on and not powering a device will consume battery power. To gauge how much power is used, refer to your battery meter. The Phoenix line of inverters can be made “Smart” and available to view via the Victron Connect App with the purchase of a “VE.Direct Bluetooth Smart Dongle.” System Integrated: A system integrated inverter installation means when the inverter(s) is powered on, your entire system becomes live, as though you were plugged into shore power. Items like outlets, microwave, and air conditioner now have power to them. The actual run time available from each load is directly dependent on how much battery capacity you have. Some trailers and 5th wheels have so many electrical options (such as 3 air conditioners, fireplace, dual residential refrigerators etc.) that you can quickly overload your inverter if too many items are powered on at the same time. To determine how much power you are using with each load, reference your Touch 50/70 (if applicable) or shunted meter via the Victron Connect App. Compare your usage to the recommended maximum output of your specific inverter. System integrated inverter installations will use one of the models listed below. The inverter model is chosen based on user power demand and trailer electrical shore power amperage. 15A Input: (uncommon, Van only)MultiPlus Compact 2000VA1,600wMultiPlus 2000VA (New Body)1,600wMultiPlus 3000VA2,400w30A InputMultiPlus 3000VA2,400wMultiPlus-II 1x120v 3000VA2,400wQuattro 24v 5000VA50A Input (Split Phase)2x MultiPlus 3000VA4,800w2x Multiplus-II 1x120v 3000VA4,800w2x Quattro 24v 5000VA1x MultiPlus-11 2x120v 3000VAExample of power consumption per appliance.

Depending on your choice of control/interface device, your exact procedure will vary. The options available for inverter control and interface are as follows. VE.Bus Smart Dongle This device lets you operate your inverter (turn on/off/charger only/current limit etc.) Observe power output and check errors and warnings through the Victron Connect App. This device is Bluetooth only and does not feature a physical interface. All inputs are made through Victron Connect. Therefore, you must have a charged phone or tablet that is Bluetooth capable (with Bluetooth turned on!) Digital Multi-Control The Digital Multi-Control is Victor's simplest method of inverter control. Featuring a switch and a dial, it allows you to turn the inverter on, off or charger only, as well as adjust the current limit. Cerbo GX and Touch 50/70 The Cerbo GX and Touch 50/70 is the most advanced interface and control option offered by Victron. Not only can you use the Touch Y50/70 screen to control your system in person, you can also interface with your system anywhere in the world via Victron VRM (Victron Remote Monitoring) if connected via the internet. Modes: OFF When “OFF” your inverter(s) are completely inactive and will not function in any way. Since shore power is routed through your inverter, shore power will not function in any way when your inverter is off. All DC systems such as lights, fan, radio, water pump ect. will continue to work while the inverter is off. ON When in the “ON” position, your inverter is fully functional and able to deliver the full rated power. When NOT plugged into shore power When the inverter is “ON” your inverter will supply power to your AC (Alternating current” breaker box, where the power will then be distributed to your AC (Alternating current/household) loads. Remember to keep your loads (power use) at or below the recommended power output of your model inverter. Check your battery state of charge regularly when using your inverter, as you could consume energy from your batteries at a much faster rate than normal. When plugged into shore power When plugged into shore power your inverters must be ON and you must set the “input current limit.” When plugged into shore power and the inverter “ON”, the inverter will distribute shore power to your AC loads, charge your house batteries, and, if needed, hybrid assist. Hybrid Assist is a revolutionary technology in inverter function. When excessive loads are placed on the inverter, exceeding the available power from shore, the inverter has the ability to temporarily stop charging the batteries and use battery power to augment available power for use. Once loads have been reduced, the inverter will resume normal operation and begin charging the house batteries. Charger Only: When NOT plugged into shore power When in “Charger Only” mode and NOT plugged into shore power, the inverter will not function. It will however consume unnecessary power from the batteries. Do NOT use “Charger Only” when not plugged into shore power. Charger Only: When plugged into shore power When using “charger only” mode while plugged into shore power, you must input your “input current limit.” When in “charger only” mode, the inverter will only distribute available power from shore power, and charge the batteries with any remaining surplus of energy not being consumed. The inverter will NOT hybrid assist in this mode. Because of the limitations of this setting with no real advantages, we recommend using either “ON” or “OFF” modes. Use this setting when in storage and keeping your system plugged into shore power. In this setting, if shore power was lost due to power outage or accidental unplugging of shore power, all AC loads that were running in the system would be turned off. This will prevent your batteries from becoming discharged inadvertently. *Input Current Limit Input current limit is used to communicate to the inverter what amperage service you are plugged into. You only need to adjust your input current limit when you are plugged into shore power or using a generator. When dry camping, the current limit does not matter. As a general rule, you should set the current limit to reflect the amperage service you are plugged into. Example: If you are plugged into a 30A service (Like at a RV Park), you would set your current limit to 30. If plugged into a standard outlet (15A) like you would find in a house or garage, set the current limit to 15. When plugged into a household outlet remember that there may be other things powered off that circuit. If you experience a tripped breaker on the service side panel, try lowering your current limit. Current limit is the maximum amount of amperage the inverter will attempt to pull from the shore supply. Operation Of Inverter with Various Interfaces To Turn Inverter ON/OF: VE.Bus Smart Dongle Open the app “Victron Connect” on your phone or tablet (ensure Bluetooth is enabled on your device.) Select the inverter from the list of available devices. Once the product is loaded, you will be able to touch the screen where it says “switch” (This also looks like the switch on your inverter) and it will populate a screen that allows you to select from On, Off and Charger Only. It can take a couple of seconds or the command to go through and turn the inverter on or off. Remember to run your inverter off when not in use. Check your battery state of charge regularly when using your inverter. Digital Multi-Control To turn your inverter on or off using the Digital Multi-Control, simply toggle the switch to the desired position. It can take a couple of seconds for the command to go through and turn the inverter on or off. Remember to turn your inverter off when not in use. Check your battery state of charge regularly when using your inverter. Cerbo GX & Touch 50/70 There are several ways to control your inverter via the Cerbo GX and Touch 50/70. 1) Using “boat and motorhome overview.” Simply swipe right on the touch screen until you reach the “boat and motorhome overview” page. At the bottom of the page will be two gray boxes. One titled “Current Limit” the other titled “State.” Touch the “State” tile and select from on, off or chargers only. 2) Touch the screen anywhere to pull up the “Pages” and “Menu” tabs. Select “Menu”. Select your inverter by clicking the row. Your inverter is likely labeled “Multiplusxxxx” or “Quattroxxxx”. Once you have selected your inverter, find and select the row that says “Switch.” From there you can turn the inverter on, off or charger only. Be sure to confirm your selection by clicking the “√” mark at the bottom of your screen. 3) You can remotely turn your inverter on/off by using the Victron VRM portal. Using VRM you can control and monitor every aspect of your system. Your system (Cerbo GX) must be connected to the internet to transmit and receive data. Please familiarize yourself with VRM by reading literature and watching videos that are available at To Current Limit: You only need to adjust your input current limit when you are plugged into shore power or using a generator. When dry camping, the current limit does not matter. VE.Bus Smart Dongle: To adjust the input current limit using the VE.Bus Smart Dongle, first open the Victron Connect app on your smartphone or tablet. Locate and select your inverter. Once your inverter has loaded, select the “Input”/”Current” tile and there you will be able to change the value. Be sure to select “Ok” after you have made your selection. Digital Multi-Control: To change the current limit using the Digital Multi-Control, simply rotate the dial (Clockwise to increase the number, counterclockwise to decrease). Your inverter must be on in order to change the current limit Once you have selected the proper current limit, no further action is required. Cerbo GX & Touch 50/70: Changing the current limit of your inverter via the Cerbo GX & Touch 50/70 is very similar to turning it off (as in they share the same screens.) 1) Using “Boat & Motorhome” overview. Simply swipe right on your touch screen until you get to the “Boat & Motorhome” overview screen. On the bottom there will be two gray boxes, one titled “Current” and the other titled “State”. Touch the “Current” box and input your desired input current limit. Be sure to confirm your selection by clicking the “√” mark. 2) Touch the screen anywhere to pull up the “Pages” and “Menu” tabs. Select “Menu”. Select your inverter. Your inverter is likely labeled “Multiplusxxxx” or “Quattoxxxx”. Once you have selected your inverter, find and select the row that says “current limit.”. From there you can change your current limit to your desired setting. You can also turn the inverter on / off this way as well. 3) You can remotely change your current limit by using Victron VRM. Using VRM you can control and monitor every aspect of your system. Your system (Cerbo GX) must be connected to the internet to transmit and receive data. Please familiarize yourself with VRM by reading literature and watching videos that are available at *Note: The need to limit current remotely is extremely rare. Fuses & Breakers: Your system features a wide array of fuses and breakers. A fuse and/or breaker is a safety device that will open a circuit during an event like a short circuit, overload or system fault. Not all fuses or breakers in your system may be easily accessible. Because of the nature of a fuse or breaker opening, indicating an unsafe condition, we do not recommend replacing the fuse or resetting the breaker without an inspection of the affected circuit. Fuses and breakers rarely open / break for no reason. Power System Terms and Acronyms SOC – State of Charge MPPT – Maximum Power Point Tracking Voltage – Voltage is the pressure from an electrical circuit's power source that pushes charged electrons (current) through a conducting loop, enabling them to do work such as illuminating a light. In brief, voltage = pressure, and it is measured in volts (V). AC Power - AC power is Alternating Power. This is the same as your household power. This will be at 120v and is extremely dangerous to work on. This side of the systems should only be serviced by a qualified electrician. DC Power - DC power is Direct Current. This power is used for items such as your lights, fans, radio, water pump etc. This system is safe to work on so long as you follow proper precautions. Current - the number of electrons that happen to be passing through any one point of a circuit at a given time. The higher the current, the more work it can do at the same voltage. Power = voltage x current. Deepest Discharge - This is the most energy you have taken from your battery pack on a single event. Cumulative Ah Drawn – This is the total amount of energy you have used from your battery bank since commissioning. This is a “lifetime” tally of total power used. Shore Power – RV shore power is a land-based power supply named for the power source used by boats when docked on shore. Most modern RVs come equipped to accept 30-amp or 50-amp power. Shore power can also be used interchangeably with a generator supply, as these two power sources ultimately go to the same place. AC Input – This is the power that is coming in from shore power or a generator. This can be expressed as watts or amps. AC Loads – This is the power that is being used through your AC / household circuits. Items such as outlets, microwaves, air conditioners will all use AC power. Typically your fans, lights, radio etc will be part of your DC (direct current) system. PV Charger – Solar Photovoltaic (PV) is the technology that absorbs and converts sunlight into electricity through solar panels. Bulk – Charging of your batteries from 0%-99% state of charge Absorption – Charging of your batteries from 99%-100% state of charge Float – The maintenance charge of keeping your batteries at 100% state of charge Synchronizations – When the shunt has had all conditions met to confirm and display that your batteries are at 100% state of charge. Time Remaining – If you keep using power the way that you are now, how long you can continue to run in this way before running out of power. Watts / Amps - These terms are used interchangeably. Keep in mind that Amps = watts when amps are multiplied by the working voltage. Example: 12A x 12v = 144w. Example: 10A x 120v = 1,200w.
