Greatly Appreciate help with Multiplus 12/3000/120, Digital Controller 200/200A, MPPT 150/50, BMV712, Lithium Iron Phosphate Battery Back (400AH), and six 100watt PV panels in RV. I have a new system, installed and connected it myself and need help setting up for use of shore power and/or 3,100 running watt inverter generator when batteries run low or I want large load support. I need help with settings to augment battery power with shore or generator when I plug into either and want to charge batteries with any extra power above the load.
I connected the RV Shore-power Cord directly to the input of the 12/3000/120 Inverter Charger and connected AC out 1, to RV's AC power panel for distribution to appliances.
I plugged my RV Shore-power plug into my Champion 3400 Inverter Generator (3100 running Watts) and ran the RV's 15000 BTU Air Conditioner for about 80 minutes. My 400AH Battle Born Battery bank dropped from 100% charge to 80% charge.
I thought the whole system would run great and keep the batteries at 100%. I obviously did something wrong. I have operated this RV air conditioner with this generator for over 200 hours prior to installing the Victron and Solar systems.
HELP!!
