[RE-wrenches] Sol-Ark 12k w/ Generac Transfer Switch

[Dave Tedeyan]

Hi Rick,
I have a similar situation with a GE transfer switch, but am curious to
hear what others have to say. 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.
Cheers,
Dave
