Enphase IQ Battery 5P with FlexPhase 5 kWh AC-Coupled Battery

The IQ Battery 5P with FlexPhase is an all-in-one AC-coupled lithium iron phosphate (LFP) battery system with 5.0 kWh of usable energy capacity. It features six integrated IQ8T-BAT Microinverters and delivers 3.84 kVA continuous power in 1-phase configuration or 1.28 kVA per phase in 3-phase configuration, with natural convection cooling and passive thermal management.

This flexible system supports both 1-phase and 3-phase grid configurations and operates in Self-Consumption and Full Backup modes. It achieves 90% AC round-trip efficiency and 96% DC round-trip efficiency, with a nominal DC voltage of 76.8 V and operating temperature range from −20 °C to 55 °C. The system uses wired control communication for reliable connectivity and integrates seamlessly with the Enphase Energy ecosystem, including the IQ System Controller 3 INT for backup operation.

Designed for wall-mount or pedestal installation, the battery meets UL 9540A safety standards and carries a 15-year limited warranty covering up to 6000 cycles or 60% capacity retention. All components are field-replaceable and the system supports remote firmware updates.
