Home Battery Prices & Comparison (2026)

The Enphase IQ Battery 5P is the most modular home battery available. Each unit stores 5 kWh and contains six embedded microinverters, so you can size a system precisely and expand it later. Its 15-year warranty is the longest in the residential market, and the all-in-one microinverter design keeps single points of failure low.

The LG RESU Prime comes in 10 kWh and 16 kWh models with strong power output (up to 7 kW continuous, 11 kW peak) for its size. It is a compact, high-density option that pairs with many third-party hybrid inverters, giving installers flexibility.

The SolarEdge Home Battery is DC-coupled to SolarEdge inverters, giving it one of the highest round-trip efficiencies (94.5%) on the market — less energy is lost moving power in and out of storage. It is the natural choice for homes already running a SolarEdge solar system.

The Tesla Powerwall 2 is the proven predecessor to the Powerwall 3. It stores 13.5 kWh and delivers 5 kW of continuous power (7 kW peak). It uses an AC-coupled design, so it retrofits easily onto homes that already have solar. Many installers still offer the Powerwall 2 where Powerwall 3 supply is limited.

The Generac PWRcell is a modular battery that scales from 9 to 18 kWh per cabinet and delivers up to 9 kW of continuous power. Backed by Generac's generator dealer network, it is often chosen by homeowners who want high power output and the option to integrate a Generac standby generator.

The Panasonic EverVolt 2.0 is a flexible modular battery offered in AC- or DC-coupled configurations, with 9 to 18 kWh of capacity and a 12-year warranty. Panasonic's long history in lithium cells and a strong warranty make it a dependable mid-premium choice.

The Tesla Powerwall 3 is the most popular home battery in the United States. It builds an 11.5 kW solar inverter directly into the battery, so a single unit can run a whole home and connect solar without a separate inverter. With 13.5 kWh of usable LFP storage and the highest continuous power output in its class, the Powerwall 3 backs up large appliances and starts well pumps and air conditioners that smaller batteries cannot.

The FranklinWH aPower pairs a 13.6 kWh LFP battery with the aGate smart controller, which manages solar, grid, battery, and even a generator in one system. It supports very large installs (up to 15 units) and is a popular Powerwall alternative for whole-home backup with generator integration.

The sonnenCore+ is a premium all-in-one LFP battery rated for 10,000 cycles — among the highest cycle life in the residential market. With up to 20 kWh per cabinet and a built-in inverter, it targets homeowners who prioritize longevity and daily cycling over lowest upfront cost.
