I live on a boat with a 13.5KW LiFePo4 battery bank with REC BMS, 4 SmartSolar MPPT, and a Multiplus 12/3000, and a Cerbo GX. Charrge control is via DVCC, controlled by my BMS. I use the AC input current limit on my Multiplus, which I adjust from the Cerbo GX, so I don't over-tax sketchy power pedestals on docks. It usually seems to work. It was working this morning in fact. Today I was running on our generator for the first time in a long time (it's been broken), and I would like to use AC input current limit so as not to overload the generator. However it didn't seem to be respecting the limit at all. Generator and shore power both use the AC-IN L1 terminals, they don't use seperate terminals, so it seems these should behave exactly the same. Does anyone have trouble shoothing ideas for why current limiting would sometimes work, sometimes not?
Any advice would be apreciated.
