Hi all, I have a bit of a mystery here that I have not been able to get a full answer yet. I spoke with two Sol Ark techs and I got two conflicting answers.
Here's a description of the problem and a breakdown of how I have the system configured. I know there is lots of knowledge in this community and some of you will have valuable input.
SYSTEM DETAILS
Residential
Grid = 3 Phase
2 × Sol Ark 15KW
Connected parallel as three phase unbalanced
Inverter Mode = 3 Phase 208v
Utility Grid is 3 phase and connected to the Grid terminals on both Sol Ark inverters
AB BC
PV and Batteries charge fully during the day and system works well... but during the night the batteries drain.
The issue is that I am searching for a way to connect a Generac 20kw 3PH generator to the Gen terminals of both inverters (unbalanced) and so the sol ark will two wire start and charge batteries during the night.
BTW I do not Grid charge because my country is stupid expensive rates for electricity.
Sol Ark documentation does not specify specs of what the Gen terminals will accept nor limitations of the Gen terminals.
Neither do the sol ark wire diagrams show a generator being used in a Parallel three phase unbalanced situation.
