This is a new installation made up of the following components:
- 28kw Solar Plant
- 33kw SMA Tripower Core 1 Solar Inverter AC Coupled
- 3 x 15000 Quattros
- 24kwh 48v OPzv Victron Battery Plant
- 80kw 3PH Generator
My issue is the system works flawlessly until it gets to about 96% battery charge at which time it becomes unstable and oscillates from 0-300 amps of charge until the Quattros shut down and restart. I have the charge current set a 50 amps and the Core 1 is set to "Island" mode. I'm testing without generator so there is no AC1 power.
Any help would be appreciated.
