Best lithium solar batteries for home storage
Researched by Deal.ai's shopping agent across stores on November 6, 2026. Prices below are today's.
Top pick: Tesla Powerwall 3 — the one to start with for most homes. It's a complete, integrated system (battery plus inverter) with 13.5 kWh usable, a strong discharge rate for whole-home backup, room to stack up to seven units, and a 10-year warranty. It's the least fiddly path to backup power.
Who the others suit:
- Enphase IQ Battery 5P — homes already on Enphase microinverters; modular 5 kWh blocks that scale in small steps.
- SolarEdge Home Battery — SolarEdge inverter owners; high round-trip efficiency and up to three batteries per inverter.
- HomeGrid Stack'd (14.4 or 38.4 kWh) — big capacity in stackable all-weather modules, over 6,000 cycles; good for serious off-grid or whole-home storage.
- ECO-WORTHY PowerMega 314 (16 kWh) — the value route to a lot of capacity if you're building a DIY or off-grid bank.
- Server-rack batteries (ECO-WORTHY Cubix100, Vatrer 48V 100Ah, SunGoldPower wall-mounts, POERUNI) — budget-friendly 48V building blocks for DIY systems; you supply the inverter and wiring.
Check inverter compatibility and local permitting before buying — a battery that doesn't talk to your inverter won't give you the backup you expect.
