Is $12,500 to add a third FranklinWH aPower 2 battery a fair price?
Project Details
I am looking for community feedback before spending more money. My current system works, but during outages/night time I want reliable AC operation. I I I'm considering adding soft-start kits (MicroAir EasyStart 364) on both AC units to reduce startup surge and keep things stable on batteries, as an alternative to buying a third battery. I was ignorant until now about heat pumps and am thinking about making the AC more efficient.
