Hello everybody,
So i run a 200wattsystem on my van. Everything ran perfectly well but now all of a sudden i get error code e3. (low battery voltage) sadly i have no clue how to get it running again.

How do i solve this?
And what does it mean exactly?

Details about the setup:
2* 100watt panels
Renogy mppt charge controller
2*110amp hour lead acid batteries.
The system runs 12volt

Best regards
Marc

Rover controller?

There is under voltage warning @ 12v and a low voltage disconnect @ 11v, this has to do with the load terminals
low voltage reconnect is 12.6v, I assume you need to recharge to 12.6v to get the load terminals to work.

If you have discharge 220 batt bank to 90% or more its gonna take a while, fire up the alternator, find sun and find utility power to recharge the batts.

The manual suggest that using the 'user' batt type that these setting can be changed. I might consider raising them to avoid deeply discharging my batts.

As i don't have any other power sources, i just unplugged everything from the battery so there is absolutely no draw. Then i left it charging for two days and now it seems to be fine again. Thank you for the hints.
