If you've left something on while your van is being stored or have otherwise run your batteries low, it is likely that you've run the batteries below multiple levels of automatic shut down, and that is why nothing seems to be working. Do not fret. Nothing is damaged.
Here's a helpful flowchart with some text below to explain some of the questions/steps in the flow chart:
Victron display is ON:
You have only run the system below the 11.5V low voltage shut down that is external to the batteries. Waking the system up is as simple as shutting the house battery switch off, then charging the van via shore power or running the engine. Once charge current is flowing into the batteries (as indicated with a positive amperage number on the Victron display or app), the house power switch can be turned back on and everything will work.
NOTE: you MUST charge for a significant amount of time to bring the system back up to a true 100% as you have run below 0% for this to occur.
Victron display is OFF:
You have run the system PAST the 11.5V low voltage shut down and below the last-line of defense which is the internal battery shut down. The batteries must be reset.
To reset the batteries:
Turn house power off and remove the plywood cover under the bench seat cushion (4 phillips screws). There's a button on top of each battery. Push and release the button on each battery. After pushing the button, the capacity lights next to the button should turn on.
If the battery capacity lights do not turn on, the battery has not turned back on. Please reach out to RoamRig for assistance by submitting a support request.
Once the battery capacity lights are all on, make sure the Victron gauge is on, then start the engine or plug into shore power. Once charge current is flowing into the batteries (as indicated with a positive amperage number on the Victron display or app), the house power switch can be turned back on and everything will work.
NOTE: you MUST charge for a significant amount of time to bring the system back up to a true 100% as you have run below 0% for this to occur. Any time the Victron gauge has lost power completely (turned off), it has lost track of where it will count up/down from and will therefore display 100% upon powering back up. THIS IS NOT TRULY 100% and you MUST CHARGE VIA SHORE POWER OR VIA DRIVING UNTIL AMPS ARE NEAR ZERO AND VOLTAGE IS MID TO HIGH 13s INDICATING A TRUE FULL CHARGE!!
It is a good idea to check each battery to confirm it is on, once the batteries have been reset. Please follow the video below
