54kWh doesn't go far for air conditioning in September in Southwest Florida. Trust me. Most homes have $200+ electric bills at $0.10/kWh this time of year, sometimes substantially more.
Generator backup, even with 4 Powerwalls, is necessary for mission-critical grid-tied backup situations. Sadly, you can't charge Powerwalls with a generator. You just bypass battery storage and run loads straight off the generator, which means the generator needs to be sized for the whole home. It would be nice to have a generator input for supplemental charging at least with a small portable unit. There is no perfect solution for this application. At least no cost-effective solution.
