The Enphase IQ Battery 5P is an all-in-one, AC-coupled storage system with six microinverters built into the battery itself. It offers 5 kWh of usable energy and is modular: the installer can size the system to the buyer's needs. The limited warranty lasts 15 years and covers up to 6,000 cycles. Commissioning requires an installer with Enphase University certification, and backup during a blackout is obtained by installing it with the IQ System Controller.
