Getting ready to help setup a 2 X Growatt 5000es system with 2 transformers.
PV side will be sized to hopefully meet 100+% of needs but we still want a generator backup to power essential loads and charge the battery bank until solar can take over (500w-1kw loads and 3-4kw for charging).
And for reference planning on initially 15kw of batteries
My question is around wiring the connection from generator to one of the inverters. Looking to leverage the 2 wire start capabilities and auto start stop settings with the Growatt.
Have a Honda 7000w inverter generator that can do either 120v @ 30a or 120/240v 30a but can not do a straight 240v. Since the Growatt only has one hot leg on the AC in side could I still wire both legs from the generator to take full advantage of the output?
Generator - L1 to L1 of Growatt (120v)
Generator - L2 to N of Growatt (120v)
Generator - G to G of Growatt
I know the AC IN range per setting 3 is 90-280v but I don't know if the Growatt will freakout when it sees 120v on the N.
Also since the inverters are going to be in parallel would that cause an issue in only having one of the Growatts connected to the generator?
Does anyone have a similar setup already?
Thanks
