I have a multiple Lithium set-up with the MultiPlus 12/3000 and am unable to get any power to my RV, even when plugged into shore. I'm hoping someone can help me isolate where the problem is.
Full disclosure: I did lend it to a friend who plugged into 50 amp by mistake, but I did have power in the RV after that. I have been unable to get power after storing the RV for about a week (solar panels were covered by roof) and I am assuming the batteries got too low.
See links below (first one is a few second video, the others are photos).
The Color Control is not getting any power and the Battery Monitor display is flashing in a strange way.
MPPT 100 50 Charge controller float light is on and battery terminals measure 13.5 V
Cyrix Li ct battery combiner has slow blue flash every 10 seconds
Display on battery protect is off
VE BUS BMS red led is on
Voltage across battery connector cables inside Multiplus measures 6V.
I did notice that the VE.Bus BMS Mains detector had come out of its case and circuit board was exposed.
Any help would be greatly appreciated.
