Hey Rick, are your loads in this scenario not all behind the SolArk (and already capable of all no-back feed scenarios including zero export?)

Generac recently released a FW code you can enter to indicate to the generator you want it to Start/Stop with 2-wire configuration. A generator that size I would feed directly into the SolArk and let the SolArk Start/Stop function. This will increase the "Up Time" of the inverter as it will always have a secondary power source it can call on when there's a low SOC.

If the inverters need to be shut down for service or happen to shut down on their own, the generator will start. Not a good design.

My assumption was that the switch transfers based on loss of 240V from the grid. But I believe (at least with the GE generator) that the transfer switch sends a two wire start signal to the inverter when the transfer switch loses the 240V signal. My plan was to rewire that start signal to the Sol-Ark inverter, but keep the transfer switch as the main service point to prevent any kind of backfeeding to the grid.

The Sol-Ark has a two wire start (NO or NC) capability, however, the Generac transfer switch operates on loss of 240V. Is my only option to use a relay driven by the two wire start to drop 240V to the transfer switch?
