Hi all this is a way I will track my progress with my powerwall
My goal is to have 100% off grid power for the whole house

Cool! As you probably know I have dual AIMS 12,000w powering my home. And I can in fact power my home in spring / summer - but winter kills me. Maybe you have sun pretty much all year round (except for occasional storms/hurricanes)?

pretty much it rains of and on but when we get storms it can be muggy for a few days so hopefully my battery will stretch the gaps
does the pair of aims inverters you have handle all the high watt appliances fine ?

Yes it does. The whole house heat pump, dryer, and cook top (with all burners on at the same time) are the largest things I power and each individually can go up to 4,500w and all run OK. My first AIMS is now 2yrs old and has produced 25,885kwh over 12,126hrs with no problems so far.
