Will a Tesla powerwall work for me?

If I designed my system correctly, I should rarely or never see the generator powering the home. PGE power is 47% from Natural Gas.

Are you sure you are going to get enough winter solar production? If you do not you are going to be getting a large fuel bill.

What happens if one of your inverters fails? What happens if your generator fails? What happens if a battery fails or your gateway fails?

You will probably want to ensure that you have paid up front for some first rate service when the inevitable piece of equipment fails that takes out your mini grid.

I have gone through long power outages, 22 days being the longest and the fuel bill for running a generator is very expensive, even while going with no power all night while sleeping...

Best of luck!

So, that suggests there is different PW setting for "true" off-grid mode where the generator is connected to the normal grid connection but with additional generator control connections and operation. It sounds similar to the Enphase generator solution where they turn on/off generator based on battery SOC thresholds and the main purpose for generator is battery charging rather than powering loads.

I was able to get a copy of the off-grid guide and the generator support works as suspected:
