<br>
Well this might not be the answer you are looking for but I'd take a
serious look at the relative hassle of rewiring the array to DC.
Sol-Ark's shine in DC coupled mode - highly efficient - and then you
have the generator port open (now not used for AC coupling) available
for the generator. Depending on how accessible the MC4s are on the
array and how easy to run DC wire it might not be that much work - with a
much superior result.<br>

dir="ltr">Hi All, <div><br><div>I am planning on using a Sol-Ark for the
first time for adding battery backup to an existing system. It is
Enphase, so clearly it will be AC coupled, and there is a whole house
generator. When I talked to Sol-Ark about it, they recommended putting
the generator on a time of use schedule to not allow it to come on
during the day so that we don't run into the issue of the solar
backfeeding the generator.</div><div><br></div><div>I was wondering
though if anyone has just used a contactor to cut out the solar when the
generator turns on? Something like Outback's GS-AC-Gen-Kit, although in
this case I will need something rated for just over 30A. This seems
like a better way to allow the generator to run at any time it is
needed, especially if it is a gloomy, snowy, winter day.</div><div><br></div><div>Cheers, </div><div>Dave<br><div><br></div>--
