Quick Answer
SolarEdge Home Battery 10K: 9.7 kWh LFP battery with 5 kW continuous / 7.5 kW peak output. NuWatt does not install this battery. Good LFP battery but locked to SolarEdge inverter ecosystem and parent company (NASDAQ: SEDG) has faced significant 2023-24 financial pressure with writedowns and layoffs. NuWatt installs Enphase IQ Battery 10C at similar capacity with a 15-year warranty from a financially stronger parent.

Runtime calculated from 9.7 kWh usable × 94.5% round-trip efficiency = 9.2 kWh effective storage, divided by average load. Duty cycles assume intermittent operation (fridges cycle ~40% of the time, AC ~50%).
Brand stability
SolarEdge Technologies (NASDAQ: SEDG) has faced significant financial pressure since 2023 with major inventory writedowns and layoffs. Home Battery product remains available but strategic commitment to residential storage is less clear than pure-battery players. 10-year warranty, but warranty enforcement over the full 10 years carries ordinary going-concern risk.

No. NuWatt does not currently install the SolarEdge Home Battery 10K. For the same use case, we install the Enphase IQ Battery 10C — see the "NuWatt's recommendation" section above for a detailed comparison.
The SolarEdge Home Battery 10K has 9.7 kWh of nameplate capacity and 9.7 kWh of usable capacity — full nameplate capacity is accessible. Use the interactive outage simulator on this page to see exactly how long that capacity will run your specific appliances.
The SolarEdge Home Battery 10K uses LFP chemistry. LFP (Lithium Iron Phosphate) is the safest residential battery chemistry available, with no thermal-runaway risk and typical cycle life of 5,000–10,000 cycles. LFP is the dominant chemistry for new residential battery products in 2026.
10-year product warranty with a 4,000-cycle guarantee (whichever comes first). Note: SolarEdge's parent company is on our watchlist — see the Brand Stability section on this page for details on warranty enforcement risk.
Yes. Residential home batteries remain eligible for the 30% federal Investment Tax Credit in 2026 when paired with solar (Section 48E) or installed standalone under the IRA provisions. This is different from the residential solar panel credit (Section 25D) which expired December 31, 2025. For commercial ITC projects, see the FEOC section on this page for domestic-content-adder eligibility.
