My 16.3 kw Solar + 2 Powerwall installation is pending and almost done with permitting. With Tesla’s more favorable financing now, I’m considering adding a 3rd Powerwall. I know my home’s AC compressor is compatible with 2 Powerwalls. Is there any clear reason for me to add a 3rd Powerwall to the install? Our daily electricity usage varies between 60-90 kwh this summer depending on our AC use and how much my car needs to charge. We have a gas furnace so electricity usage will be lower in the winter, though we also have an electric dryer.
Also, our utility will be starting some fairly high time-of-use rates, especially between 4-8 pm, some time later this year.
Happy to get any input people can give. Thanks!
