Efficiency basis: AC round trip (DC round trip is 96 percent). Round-trip numbers are only comparable across brands when measured the same way, so read the basis before comparing.
Capacity note: the 10.0 kWh figure is the 10C's own, from the IQBATTERY-10C-1P-NA datasheet. Do not confuse it with Enphase's earlier IQ Battery 10 (ENCHARGE-10-1P-NA, formerly Encharge 10), a separate second-generation product built from three IQ Battery 3 base units at 10.08 kWh usable, which enphase.com still lists but shows as out of stock.

Specs do not tell you if it pays off.
Payback depends on your rate plan, usable capacity, and local incentives, not the brand on the box.
