Hi there. I upgraded a system for a client to the following:
2x Victron Multi II 48V 3kVa in set up in parallel on a 10.4kWh Lithium bank.
Venus GX with BMS CAN
Was working perfectly as load shedding backup. I have now added a 4000Wp solar array
with Smarsolar 250/100 Mppt.
After loading the assistant, I set up system to discharge batteries down to 60% (unless grid fails).
Everthing performed as expected, however about a hour after the batteries reached 60%, we had a load shedding occurrence. Instead of the inverter taking over from grid with remaining battery capacity, it shut the loads down completely.
I have worked thought some options, but can not find any clear cut answers.
Any advice would be appreciated
