Hi All, 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.
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.
