Enphase IQ Battery 5P 5.0kWh AC Coupled Battery

About This Product

The Enphase IQ Battery 5P 5.0kWh AC Coupled Battery is a modular residential energy storage battery designed for the Enphase Energy System in North America. This domestic-content version uses the manufacturer model IQBATTERY-5P-1P-NA-DOM and provides 5.0 kWh of usable energy storage. It is an AC-coupled design with six integrated grid-forming IQ Microinverters, allowing the battery to connect on the AC side of the electrical system rather than requiring a separate battery inverter. This kit includes one IQ Battery 5P, cover kit, wall-mount bracket, and top shield.

Who This Product Suits

The Enphase IQ Battery 5P is suited to residential Enphase installations requiring modular energy storage for solar self-consumption, energy management, or backup applications. Its AC-coupled architecture makes it suitable for new Enphase systems as well as compatible retrofit applications where an installer wants to add storage on the AC side. Multiple IQ Battery 5P units can be combined where greater storage capacity or output power is required. Backup operation requires the appropriate compatible Enphase system equipment, including an IQ System Controller, with the complete installation designed and commissioned in accordance with Enphase requirements and applicable NEC requirements.
