SolarEdge Home Battery (400V) vs Enphase IQ Battery 5P
A straight, side by side read on specs and warranties, with the honest caveats. Every figure is from the manufacturer datasheet; sources are at the bottom.
| Spec | SolarEdge Home Battery (400V) | Enphase IQ Battery 5P |
|---|---|---|
| Chemistry | Not published | LFP |
| Usable capacity | 9.7 kWh | 5 kWh |
| Continuous power | 5 kW | 3.84 kW |
| Peak power | 7.5 kW | 7.68 kW |
| Round-trip efficiency | 94.5% | 90% |
| Warranty | 10 year limited product warranty | over 60 percent capacity at up to 15 years or 6,000 cycles |
| Backup scope | Partial / essential loads | Whole-home capable |
| Inverter | Separate | Integrated |
What actually differs
- More usable capacity: the SolarEdge Home Battery (400V) offers 9.7 kWh vs 5 kWh, so at that size it carries more of your home for longer per charge.
- More continuous power: the SolarEdge Home Battery (400V) sustains 5 kW vs 3.84 kW, which matters for running big loads like an AC at once.
- Longer warranty term: the Enphase IQ Battery 5P is warranted 15 years vs 10, though always read the throughput or cycle cap too.
- Integration: the Enphase IQ Battery 5P has a built-in inverter, while the SolarEdge Home Battery (400V) needs a separate one, which affects install cost and complexity.
- Efficiency is not apples to apples here: the SolarEdge Home Battery (400V) quotes 94.5% (peak round trip efficiency) and the Enphase IQ Battery 5P quotes 90% (AC round trip (DC round trip is 96 percent)), so do not read the raw numbers as a direct ranking.
Which one pays off is a numbers question.
Neither spec sheet tells you the payback in your home. That comes from your rate plan and incentives.
