Hello, please can somebody help me?
I have installed island system (without grid availible) with MPII 15000 (but using only for basic consumption in house, not large loads). I have connected 10kVa generator with autostart.
When I start the generator, the all system is acting like it is charging batteries (28,6kWh US5000) but it really doest charge not even 1% when generator runs for 20 minutes)
What I donr understand is, that DC charging current and AC-IN current are moving up and dow, AC is moving from 14 to 34A and DC is moving up and down ratio equal to AC. This happens in second intervals. It shows AC values for example 14, 22, 34, 21, 16 etc.
During this try of charging, loads on ACout1 were constat 1700W, so I dont undrestand why that pulsing of amps.
On VRM it shows that is charging battery, but it does not charge anything.
I have also installed MPPT 450/200, but I turned it off because I want to test charging batteries from generator.
I have one idea - should I have installed ESS assistant? Because it is not installed in MP.
Thank you a lot for every valuable advice
