[RE-wrenches] sol ark AGS question

[Jason Szumlanski]

I just replaced two Sunny Islands and one Sunny Boy that I did not install
with a single Sol-Ark 15k today. The generator installer (not me) had
already installed a custom but simple time delay relay. I didn't get into
the logic of it, but from what I understand the generator already had a
cool-down period when remote start signal is lost, but no warm up delay.

Major deficiency? I think that is actually pretty accurate and Sol-Ark
should fix it, but it isn't too hard to take care of it another way.

I wonder if this has something with the distinction of accepting generator
input on the grid input as well. You would not want a grid delay if it were
a utility. Still, they should be able to build in that logic I would think.
