Our take on the Enphase IQ Battery 5P

The Enphase IQ Battery 5P is a 5 kWh home battery built around cobalt-free lithium iron phosphate cells, with 3.84 kVA continuous output and a 7.68 kVA three-second peak. It carries a 15-year limited warranty and about 90% AC round-trip efficiency. The best new price is $3,129 at eBay as of November 6, 2026, and only one store lists it new, so there is no meaningful recent range to compare against.
