IQ Battery 5P with FlexPhase

Enphase IQ Battery 5P with FlexPhase is a current AC-coupled battery which can be configured for single-phase or three-phase operation. Its order code is IQBATTERY-5P-3P-INT, distinguishing it from the earlier single-phase IQBATTERY-5P-1P-INT product.

Capacity and output

The battery has 5.0 kWh usable capacity and six embedded IQ8T-BAT microinverters. Maximum continuous output is 3.84 kVA in single-phase configuration. In three-phase configuration the same maximum total is divided as up to 1.28 kVA per phase.

Lower power settings add the configured output and phase arrangement to the base code:

Complete configured model	Rated continuous apparent power
IQBATTERY-5P-3P-INT-1.65-1P	1.65 kVA single-phase
IQBATTERY-5P-3P-INT-2.50-1P	2.50 kVA single-phase
IQBATTERY-5P-3P-INT-3.00-1P	3.00 kVA single-phase
IQBATTERY-5P-3P-INT-3.68-1P	3.68 kVA single-phase
IQBATTERY-5P-3P-INT-1.84-3P	1.84 kVA total / 0.61 kVA per phase
IQBATTERY-5P-3P-INT-2.50-3P	2.50 kVA total / 0.83 kVA per phase
IQBATTERY-5P-3P-INT-3.00-3P	3.00 kVA total / 1.00 kVA per phase
IQBATTERY-5P-3P-INT-3.68-3P	3.68 kVA total / 1.23 kVA per phase

For example, IQBATTERY-5P-3P-INT-2.50-3P identifies 2.50 kVA total continuous output in a three-phase configuration. The unsuffixed order code retains the default maximum schedule.

System arrangement

The product is AC-coupled and uses LFP cells. Backup requires IQ System Controller 3 INT and a supported protected-load design. The complete battery code, configured phase arrangement and power setting determine which output schedule applies.

Warranty

Covered IQ Battery 5P products activated on or after 15 September 2025 have a 15-year or 6,000-discharged-cycle warranty, whichever comes first, subject to the full terms. The Great Britain territory is Scotland, England and Wales. Northern Ireland needs its applicable document.
