2 Quattro in 120/240 (first L1+N, second L2+N)
2 Fronius 120/240 in parallel (each has L1, L2, and N)
CCGX sees the Quattro as one system
CCGX sees the two Fronius as separate inverters
In the "PV Inverters" config I have to assign the PV inverters to a phase:
But of course this makes no sense, because both Fronius inverters operate across both phases.
I feel like this is throwing off the zero feed-in and phase compensation features, as well as the reporting.
If I go into one of the inverters to look at the power:
1575W is the total power that inverter is making on both phases. ESS is counting it all towards phase 2.
