3x6kw in 3ph. 3phase gen on aux port problems
Hey all,
Have 3phase system from 1phase 3x 6kw inverters in parallel. (Master A, Master B, Master C)
I brought 8kw 3phase generator to cover any power outages at winter. Generator is connected to AUX port.
The problem is.
I set minimum Gen power in Aux settings (like 600w) which should be accordingly 3x600w= 1.8kw. The system doesnt start normaly. It ticks for power and drops off.
I clear all loads at the inverters by turning the house breaker switches (so the house icon is 0), and the system starts with 600w power.
Okay another approach.
I set Gen power in Aux settings 2500W which should be accordingly 7,5kw The system start normal. Loads on inverters are present, all works good. Until any of the inverters have a 2-3kw load power spike. Gennie falls off, and then reconnects. The house lights during this process flicker a bit, TV can turn off. I guess it is due to single phase asymmetric overload of the generator.
Am i missing something, shouldn't the inverter only allow to consume the max Gen power i set (500w? 2200W?)
Why am i unable to boot with 500w setting? Maybe any check box tick is needed in settings?
Ideally for me is that Aux port should only go to the battery, and Loads go only from battery. Inverter is making an GEN AC passthrough to LOAD for easier working conditions. Any spike on 1 phase drops off the gennie for me.
As I indicated the generator will try and supply charge to the batter and supply the load
The Smart load option only supplies power when the required parameters are met. ie there is enough PV and the battery SOC is met.
