The trusted Enphase IQ Battery 5P is about to get even better for Australian solar installers. Enphase has introduced a new variant of its popular 5P battery, now featuring FlexPhase technology—a major step forward for those working with three-phase solar systems.
At its core, this battery is still the reliable IQ 5P solar installers know well: 5.0 kWh of usable capacity, built-in IQ8T microinverters, passive cooling, AC-coupled simplicity, and all the smarts Enphase is known for. The big upgrade? FlexPhase, a new Enphase innovation that allows the same battery hardware to be configured for either single-phase or three-phase backup.
What is Enphase FlexPhase?
FlexPhase is a unique control architecture that enables an Enphase battery to intelligently balance and deliver power across multiple phases. With this feature, installers can use the same battery model for both single-phase and three-phase configurations. It simplifies inventory, reduces system complexity, and broadens the range of projects where the IQ Battery 5P can be deployed—especially in commercial or larger residential installs where three-phase power is standard.
This means one product, one installation method, and greater design flexibility without sacrificing power delivery or performance.
