We want to add a battery backup to our solar system in 2024. I was pretty set on getting the Franklin LFP batteries, because I prefer to have LFP chemistry in the house, plus we had a good experience with that installer already. But after checking the costs of Tesla Powerwalls, it's making me second guess that decision. The Powerwall, in the surface, looks way cheaper. Can anyone explain if I'm missing anything here? Are there hidden costs with the Powerwall I'm not considering?
Powerwall 2 (x2)
Total capacity: 27 kWh
Estimated cost with installation: approximately $24,000 (based on browsing Reddit posts)
Franklin Home Power LFP (x2)
Total capacity: 27.2 kWh
Estimated cost with installation: $31,000 (quote from company that installed our solar)
If it matters, we've got a 11.5 kW solar system, with net metering from our power company, plus I drive a Tesla.
