The SolarEdge Home Battery is a 9.7 kWh DC-coupled battery that pairs with SolarEdge’s Home Hub inverter, according to SolarEdge’s North America datasheet. SolarEdge lists 5 kW of continuous output, 7.5 kW of peak output for 10 seconds and a 94.5% peak round-trip efficiency, and it allows up to three batteries on one inverter. This review uses SolarEdge’s published datasheet, product page and limited warranty for every spec. We haven’t tested one ourselves.

What the Specs Mean
- 9.7 kWh usable at 100% depth of discharge. SolarEdge rates the full 9.7 kWh as usable, so you don’t subtract a hidden reserve. You can still set your own backup reserve in the app.
- 5 kW continuous, 7.5 kW peak. Five kilowatts covers a fridge, lights, internet, a furnace fan and a few kitchen loads at once. The 10-second peak helps with motor starts. SolarEdge’s product page says the battery can run HVAC systems and pool pumps, but check your equipment’s starting current against the inverter and battery limits with your installer.
- DC coupling. Solar charges the battery on the DC side of the Home Hub inverter, so energy isn’t converted to AC and back before it’s stored. SolarEdge says this avoids the “triple conversion penalty,” and its datasheet lists 94.5% peak round-trip efficiency.
- Weather Guard. SolarEdge’s mySolarEdge app can charge the battery automatically when severe weather is forecast.
Compatibility and Expansion
The SolarEdge Home Battery 400V works with the SolarEdge Home Hub inverter for North America. It isn’t a stand-alone AC battery you can bolt onto any solar system. SolarEdge allows up to three batteries per inverter, for 29.1 kWh, and each battery after the first needs a pair of branch connectors (sold separately). Floor stands or wall-mount handles are also accessories. SolarEdge’s page notes DC oversizing of up to 200% on the inverter side and says stacking batteries on one inverter can help avoid a main panel upgrade.
If you already have SolarEdge optimizers and an older SolarEdge inverter, ask your installer whether adding storage means swapping to a Home Hub inverter.
Warranty in Detail
SolarEdge’s limited warranty for the Home Battery 400V (effective January 1, 2026) covers workmanship, materials and energy capacity for 10 years from the earlier of the installation date recorded in SolarEdge’s monitoring portal or 12 months after shipment. It guarantees 70% energy retention at the end of the period with unlimited cycles for normal uses such as solar self-consumption, time of use and backup. If a third party manages the battery (for example, some utility programs), coverage is capped at 26 MWh of throughput.
The warranty is transferable to a new owner as long as the battery stays at its original site. For how this compares with other brands, see our home battery warranties compared guide.
How It Compares to Powerwall 3, Enphase 5P and FranklinWH
| Spec | SolarEdge Home Battery | Tesla Powerwall 3 | Enphase IQ Battery 5P | FranklinWH aPower 2 |
|---|---|---|---|---|
| Usable energy | 9.7 kWh | 13.5 kWh | 5.0 kWh | 15 kWh |
| Continuous power | 5 kW | Up to 11.5 kW | 3.84 kVA | 10 kW |
| Coupling | DC (Home Hub inverter) | DC solar input built in | AC-coupled | AC-coupled |
| Chemistry | NMC | LFP | LFP | LFP |
| Warranty | 10 yr, 70% | 10 yr, 70% (US) | 15 yr or 6,000 cycles | 15 yr or 60 MWh |

- Versus Powerwall 3: Powerwall 3 stores more per unit and supplies much more continuous power from one box. SolarEdge is the natural fit if you’re building around SolarEdge optimizers and the Home Hub inverter. Read our Tesla Powerwall 3 review.
- Versus Enphase IQ Battery 5P: Enphase is AC-coupled and pairs most simply with Enphase microinverter systems. SolarEdge is DC-coupled to its own inverter. Each makes the most sense inside its own ecosystem.
- Versus FranklinWH aPower 2: FranklinWH is AC-coupled, so it can retrofit onto many existing solar systems, and it carries a longer warranty term. SolarEdge offers higher round-trip efficiency on new DC-coupled builds.
Who It Suits
- Homes installing new SolarEdge solar with optimizers and a Home Hub inverter, where storing DC solar directly is the most efficient path.
- Homeowners who want to start with one battery and add up to two more on the same inverter.
- Net billing customers who want to shift midday solar into the evening.
Who Should Look Elsewhere
- Homes with an existing microinverter system, where an AC-coupled battery is usually the simpler retrofit.
- Homes needing more than about 5 kW continuous from one battery for big motor loads, unless the design adds batteries or load management.
Sizing Example
Illustrative inputs: a home that uses 10 kWh overnight (6 p.m. to 7 a.m.) and wants a 20% backup reserve.
- Energy needed: 10 kWh ÷ (1 − 0.20) = 12.5 kWh of battery.
- Batteries: 12.5 ÷ 9.7 = 1.3, so two SolarEdge Home Batteries (19.4 kWh).
- Power check: list what runs at the same time. If the evening peak is 4 kW (cooking plus HVAC fan plus fridge), 5 kW continuous from one battery covers it, with the inverter’s own rating as the other limit.
- Outage runtime: if an outage starts with both batteries full, 19.4 kWh at a 1 kW average backup load lasts about 19 hours before solar recharge.

Questions to Ask a SolarEdge Installer
- Will my system use the Home Hub inverter, and is my existing SolarEdge inverter compatible or does it need replacing?
- How many batteries do you recommend, and what’s the continuous power of the full system, not just one battery?
- Which circuits will be backed up, and is a backup interface or critical loads panel part of the quote?
- Will the battery be indoors or outdoors, and does the location stay within SolarEdge’s temperature limits?
- Is the battery registered in SolarEdge monitoring at commissioning so the warranty start date is recorded?
- Will any utility or virtual power plant program manage the battery, and does that trigger the 26 MWh warranty cap?

Price and Incentives
SolarEdge sells through installers, and prices depend on the inverter, number of batteries, electrical work and permits. We aren’t publishing a figure we can’t verify. Get quotes from certified SolarEdge installers. There’s no 30% federal credit for homeowner-owned systems installed after December 31, 2025 (IRS), so check state and utility programs instead.
Electrical work can be dangerous: follow the manual, fuse and size every cable correctly, and use a licensed electrician for anything connected to household wiring.
FAQ
How much does one SolarEdge Home Battery store?
9.7 kWh of usable energy at 100% depth of discharge, per SolarEdge’s datasheet.
How many SolarEdge batteries can I connect?
Up to three per SolarEdge Home Hub inverter, for 29.1 kWh. Additional batteries need branch connectors.
Does the SolarEdge Home Battery work with any solar inverter?
No. The 400V battery is designed for the SolarEdge Home Hub inverter for North America. Check SolarEdge’s compatibility list with your installer.
What is the SolarEdge Home Battery warranty?
