Quick Answer
The best battery for an Enphase is the Enphase IQ Battery 5P

What Batteries Work with an Enphase?
The Enphase is a microinverter system with no DC battery port. You need an AC-coupled battery — one with its own built-in battery inverter that connects at the switchboard independently.
Enphase is a fully closed ecosystem, only Enphase IQ batteries work with Enphase microinverters. The IQ Battery 5P is AC-coupled and modular (stack up to 16 units). The trade-off: ecosystem lock-in and higher cost per kWh, but an industry-best 15-year warranty and exceptional monitoring.
