- Anker SOLIX X1 starts at 5 kWh, scales to 180 kWh, and pairs a 20-millisecond switchover with an IP66 enclosure and a 10-year warranty.
- BLUETTI EP800 starts with two B500 batteries at 9.92 kWh, expands to nearly 40 kWh and 7.6 kW, and can charge from off-peak grid power without rooftop solar.
- Enphase IQ Battery 5P combines with IQ8 microinverters, Sunlight JumpStart and a third-party standby generator to power a home off-grid for extended periods.
- FranklinWH aPower S stores 15 kWh of usable energy, delivers up to 10 kW continuously, and can be controlled as part of a larger virtual power plant.
- GM Energy Home System combines 10.6 kWh of storage with GM EVs, can use vehicle power during emergencies, and is listed from $11,897.
- Sigenergy V2X adds V2H support for Tesla Model 3 and Y vehicles, other EVs using DIN70121, and several VW, Audi, Porsche and Mercedes-Benz models using ISO15118-2.
- Villara VillaGrid+ earned EnergySage’s highest Equipment Rating System score, while a related 5.75 kWh VillaGrid costs nearly twice the Powerwall per kWh and Villara’s LTO batteries carry 20-year warranties.
Why it matters: For homeowners weighing home storage, choices range from a modular 5-to-180-kWh setup to a 10.6-kWh GM package listed from $11,897; the trade-off is stark at the premium end, where a related VillaGrid model costs nearly twice Tesla’s per-kWh rate despite a 20-year warranty.
