Generac to Sol-Ark 15kw

[Oldphile]

According to Sol-ark, and implied by instructions in the manual, the inverter can tell if grid or generator connected on the grid line. That is also the way large generator is attached (exceeds capacity of Gen Input). I'm guessing that if the Sol-ark sees a "stiff" grid input line, then it assumes Grid. If the input is not stiff, then it assumes generator, and uses generator parameters.

No. The controller gets it's power from T1, not N1 N2. N1 N2 are the L1 L2 sense voltage. My Generac installer came out 3 times because he didn't have 120 VAC to T1. He even replaced the battery before he figured it out.
