I will have to do that, their engineer is actually going to talk to solar edge but I'm afraid all this is not being translated properly. I did specifically mention the issue with the breakers being in the main panel, he didn't think it would be an issue b/c the inverter will Sync to Edison and did not think it would sync to the Generator which is 60Hz and i don't believe you can change this. I assume Edision comes in at 60Hz as well?
Here is the datasheet for the generator.

I will say if I was a solar company and something broke bc you had a generator and inverter that weren't isolated from each other I'd definitely be saying it broke bc of that.Leave a comment:

Well, since it looks like you have a simple grid tie inverter, after the $600 , 200A Transfer switch is installed, the easiest way is to set the generator to 61Hz That way the solar will never be able to qualify it and life should be good.
Or it can be accomplished with a pair of transfer switches.
That's why planning ahead is critical, building up stuff piecemeal gets expensive fast.
But realize there will be a 30 second to 2 minute blackout while the generator starts up and prepares to take the loadLeave a comment:

This would void the warranty from the Solar installer who installed the equipment originally. I have a 20yr warranty with them, not willing to risk this.Leave a comment:

I'm no genius at this as I too am a neubie, but the description you give makes this an impossible situation. The ATS has to select either Generator OR GRID / Solar to feed the breaker panel. With the solar system fused into the main breaker panel, I see only trouble on the horizon. It seems that this change over would be better served by a manual process on power fail.Leave a comment:

Believe me it does not sound complicated but it is and the installer has a valid question and concern no one is addressing.
Edison power goes out > Inverter shuts off
Now we introduce an ATS and Generator.
Edison power goes out > ATS kicks over Generator supplies power to the Main panel. The Main Panel has 30A Solar breakers which I assume once the Generator is powering up the entire Main Panel the Solar Inverter also powers up b/c of those breakers in the main panel? Do you see the dilemma here? If the inverter only turns on when Edison power is on that is fine but if the inverter is getting power through the main panel and the Generator is connected to the main panel does this not cause the Sync issue and problem described above?
The inverter is only up when the grid contactor of the ATS is on.

As was said it's as simple as removing the solar breakers and doing a tap b4 the ATS.
basically this in a nutshell

Power goes out
Inverter shut downs
ATS cuts off grid and inverter from MSP

I wouldn't want to risk the generator and the inverter bumping heads in the electrical system. Its alot of money to be messing around with.
This is not that complicated. The ATS isolates the grid from the generator..... hook the inverter up to the grid side b4 the ATS so it isolates the grid AND the inverter from the generator.
You can also use some kinda relay that is normally closed but will open if it senses power from the generator feed circuit.Last edited by Markyrocks69; 07-30-2019, 12:27 AM.Leave a comment:

Spoke to the installer, and his concern was when the generator is running it is obviously supplying power to the main panel which has the Invterter Solar breakers. Is this going to cause a problem with the solar producing power and trying to pump it to the grid?Leave a comment:
