A typical home battery with installation runs into the thousands in every market. The price depends on usable capacity, chemistry, brand, and whether it’s AC- or DC-coupled to your solar.
Rough installed cost by region (planning guide)
| Region | 5 kWh | 10 kWh | 15+ kWh |
|---|---|---|---|
| United States (USD) | $8k–$12k | $12k–$18k | $18k+ |

Chemistry: LFP has become standard
Most modern home batteries use lithium iron phosphate (LFP), which offers good cycle life, strong safety, and no cobalt. Older lithium-ion NMC chemistries are fading from the residential market.
