Generac Generator + SolarEdge Inverter

[malba2366]

As others have said line side taps before the automatic transfer switch (on the grid side). A bigger concern is that your "installer" doesn't seem to know how this all works. I would find a licensed electrician (who knows what he/she is doing) to install the standby generator.

This guy is licensed, just not a solar expert, and the solar guys don't do generators.

I did get permission in writing from the solar company to allow the electrician to do what ever is needed and it won't void the warranty after i explained what we would do with the fused safety switch conversion.

Now just waiting for the generator to show up.

Have to thank you guys all for the feedback. As usual invaluable information from this forum and the experts on here.

So what did you decide on doing?

seems the options are
1- move the PV from a breaker to a line side tap with an extra breaker in line
2- create a critical load panel that the generator feeds and put the ats there.

Planning on using this instead of the existing non fused safety switch

Lol you know why that one is so cheap?....its for indoor use only

Thanks for catching that, explains the price difference, think im going to stick the outdoor HD double pole switch unless I find an outdoor one at lowes which is closer to me.

Where are you putting this? Between your inverter and your main panel?

Would you turn it off manually when the power goes out?

No it would all be automatic, right now the solar breaker is in the master service panel. With the breakers removed and converting to this fused safety switch it will be wired to Line Side Tap on the grid side of the automatic transfer switch. So when shore power goes out the solar inverter shuts completely off, than the generator will power the master service panel and the whole house minus the inverter. When shore power comes back on the inverter is back online.
