Enphase Energy Launches IQ Battery 5P with FlexPhase in India, Enabling Single-Phase and Three-Phase Backup for Homes and Small Businesses

FREMONT, Calif., Oct. 06, 2025 (GLOBE NEWSWIRE) -- Enphase Energy, Inc. (NASDAQ: ENPH), a global energy technology company and the world's leading supplier of microinverter-based solar and battery systems, today announced the launch of the IQ Battery 5P with FlexPhase for customers in India. The system provides reliable backup power and supports both single-phase and three-phase applications, serving India’s growing residential and small commercial solar markets.

Three-phase service is widely available in India, making it well suited for higher-load homes and small businesses. Each 5 kWh battery delivers continuous power of up to 1.28 kW per phase in three-phase configuration and 3.84 kW in single-phase configuration. The battery is designed to discharge up to two times the maximum continuous power for three seconds, enabling the operation of high-power devices during a grid outage when paired with the IQ System Controller 3 INT. It utilizes lithium-iron phosphate (LFP) chemistry, which is known for its thermal stability and safety profile. The battery is modular and expandable, so customers can start with a single battery and scale up to 40 kWh of capacity as their energy needs grow.

“Many of our customers live in larger homes with three-phase wiring,” said Harsha Kuntur , founder and managing director at Ecosoch Solar, an installer of Enphase products in India. “The IQ Battery 5P with FlexPhase is exactly what we need to offer reliable backup and maximize self-consumption for these households.”

“In cities like Bengaluru, homes and small businesses are increasingly asking for battery solutions that can handle three-phase loads,” said Dijo MD, director and CTO at 3rd Eye Security Systems, an installer of Enphase products in India. “Enphase is giving us the flexibility to serve both commercial and residential customers with one system.”

“Reliability is critical when it comes to energy storage in India,” said Shivam D Rai, proprietor at Shivshakti Enterprises, an installer of Enphase products in India. “The IQ Battery 5P with FlexPhase now addresses the three-phase segment with a high-performance product from a company we trust.”

The launch in India builds on Enphase’s rapid global rollout of FlexPhase technology, which is now available in 18 European countries, Australia, and New Zealand. This expansion demonstrates Enphase’s commitment to bringing flexible, high-quality energy storage to markets with diverse grid standards.
