My power won't turn on

If nothing in your van will turn on and the Victron gauge is off, it's likely that the batteries are depleted and have shut down to protect themselves. But don't fret - nothing is damaged!

First step (for all RoamRig systems), Checking Your Breakers

1st Generation Revels*: the breakers are on the front of the bench seat above the heater vent. Watch our video to learn how to access the DC breakers.

2nd and 3rd Generation Revels*: the breakers are above the batteries in the back of the van. Watch our video to learn how to access the breakers and batteries.

*Guide: What Generation of Revel Do I Have?

If the breakers are on, the Victron gauge is off, and the system won't turn on, it means that your batteries have reached a low voltage shut down. You will not be able to charge the batteries until they have been woken back up. No amount of driving or plugging into shore power will correct things until they are back on.

What happened??

You likely left the system on for an extended period of time and ran out of power. When storing your van, it is very important to shut everything off (including the batteries, if you have Lithionics batteries that can be turned off). The batteries that RoamRig installs have multiple safety mechanisms to protect them when power is low and eventually depleted. Depending on the level of shutdown, there may be a few steps you’ll need to take to power the system back on. 

1st Generation Systems in 2018-2020 Revels

If you have a 1st Generation System, follow the steps below to wake the system up:

  1. Press the button on each battery to wake them up. If the Victron gauge powers up and turns on, you can skip to step 4, charging the batteries fully (see video below).
  2. If the Victron gauge does not power up, you will need to use jumper cables and your starter battery or another vehicle starter battery to wake the batteries up to allow charging (see video below).
  3. Once the jumper cables are connected and the gauge is on, ensure that all circuit breakers are on, all batteries have had the buttons pushed (and the light on the battery turns on momentarily),
  4. Start charging via shore power or start the engine (see video below).
  5. Ensure that charge activity is occurring by looking for POSITIVE AMPS on the Victron gauge. If you DO NOT see POSITIVE amps, then the system is not charging and you will need to reach out to RoamRig for additional support (see video below).
  6. Disconnect the jumper cables once the system is on/charging. 
  7. Keep the engine running or keep the van plugged into shore power for a half hour or so. You MUST ensure that all circuit breakers on the front of the bench seat stay on during this time. If one trips or they continually trip, please reach out to RoamRig for additional steps to take. 
  8. Disconnect from shore power, turn the engine off, and turn off the solar/alternator breaker and isolate each battery with a light load on the system via the circuit breakers to ensure that each battery is on and taking a light load (see video below).
  9. Once you have confirmed that each battery is on/working, turn all circuit breakers back on, reconnect to shore power, or start the engine and drive to complete a full charge. Once you get things started and the Victron gauge is powered back up, it will default to 100% SOC. This is NOT correct. In order to make it correct, you need a FULL charge. If the gauge says 100%, but there's significant positive amps (indicating charge activity from shore power or the engine running), then you are not actually at 100% (see video below).
  10. Keep charging until amps are close to zero. Overnight for shore power, or 4 hours of driving. Once amps are close to zero, you are fully charged, and the percentage reading will be correct. Once amps are close to zero and charge sources are in float, percentage may be slightly below 100%. This is OK (see video below).

 

Once you get things started and the Victron gauge is powered back up, it will default to 100% SOC. This is NOT correct. In order to make it correct, you need a FULL charge. Instructions for charging after a full system power-down are at the end of this guide.

2nd and 3rd Generation Systems in 2021-2024 Revels

If you have a 2nd or 3rd Generation RoamRig system in your 21-24 Revel, The steps are similar to above, but you will use the Lithionics app and buttons on the batteries to wake them up. When the battery is awake, you should see it in the Lithionics app. For more, watch our video to learn how to reset your batteries (the video shows a 2nd gen system, but the process is the same for 3rd gen systems). 

  • Use the Lithionics App to see if the batteries are on. If they are visible in the app but each battery status is "off" then they are likely in low-voltage protection mode. Press the little button on each battery so that the status is "on" and then follow steps 4-10 above to fully charge your batteries.
  • If you do not see the batteries in the Lithionics app, they may be in a deep protection mode. Press the button on each battery to see if they wake up and are visible in the app. If you do not have a charge source available immediately, they may turn off after 30 seconds and need to be reset again via the button. Once all batteries are woken up and a charge source is connected, they should begin charging and follow steps 4-10 above to fully charge your batteries. 
  • If you cannot get the batteries to wake up with a button, you may need to use jumper cables similar to steps 1-3 above to get the Lithionics batteries awake. Connect jumper cables to a 12V source like your Mercedes Chassis battery and then hit the button on each battery to wake them up before charging.

When power is restored to the Victron gauge, it will default to reading 100% SOC. This CANNOT be trusted until the system has been fully charged. See steps 9-10 and the video above on how to fully charge your system and confirm that it is actually at 100%.
