Enphase IQ Battery 5P Flexphase

Enphase IQ Battery 5P with FlexPhase – Powerful and Safe Home Battery

The Enphase IQ Battery 5P with FlexPhase is an advanced, all-in-one AC-coupled home battery with 5.0 kWh of usable energy capacity. Thanks to its unique FlexPhase technology, this battery can be used flexibly in both single-phase and three-phase installations – ideal for the Dutch market, where three-phase connections are the norm. The system comprises six integrated IQ8T-BAT microinverters and delivers up to 3.84 kVA of continuous power in a single-phase configuration, or 1.28 kVA per phase in a three-phase configuration.

Key features

• Versatile: Suitable for both single-phase and three-phase installations. Switching between modes is simple by removing the jumper block.
• Safe and durable: Lithium iron phosphate (LFP) battery chemistry for maximum safety and long service life, evaluated in accordance with UL 9540A.
• High efficiency: 96% DC round-trip efficiency and 90% AC round-trip efficiency.
• Reliable performance: No moving parts or fans thanks to passive cooling.
• Back-up during power cuts: When used with the IQ System Controller 3 INT, the battery automatically supplies power in the event of a grid outage.
• Smart monitoring: Control and insights via the Enphase App. Supports remote software and firmware updates.
• AI optimisation: Automatically adapts to dynamic energy tariffs for maximum savings.
• Scalable system: Up to 14 batteries can be combined for a maximum storage capacity of 70 kWh.
• Suitable for both outdoor and indoor installation: IP55-rated housing, suitable for all weather conditions.
• Extended warranty: 15 years or 6,000 cycles whilst retaining over 60% of capacity.
