My system has developed a problem that I hope someone can provide a solution. I have Multi 2/5k/48v system with 3x genz 3kw modules (174ah). Just recently when the float voltage is reached (55.4vdc) it keeps rising (if I let it) to 62vdc when the Multi will switch off (or the battery BMS switches off??) I normally go and switch the solar off which causes the system to invert. (The GENZ LIFEPO batteries are designed as a drop in replacement for AGM etc and has no external BMS only its built in management)
The system has been fine up until recently. I tried updating CCGX and multi but to no avail. The BMV is set as recommended - Abs = 57.6, Float = 55.4.
System: Multiplus 2 5000 48vdc (An early model, Colour CCGX, VE Bus Smart Dongle and Enphase S270 (3kw) Solar on AC1 Out.
Has anybody come across this before?
Cheers - Paul
