Insights

Product & Market Strategist

Enphase launches a modular LFP battery with FlexPhase in India, enabling single‑ and three‑phase backup and immediate shipments.

Enphase introduces the IQ Battery 5P with FlexPhase for India, a 5 kWh LFP module that supports single‑phase (3.84 kW) and three‑phase (1.28 kW per phase) continuous output and short bursts at twice continuous power for three seconds when paired with the IQ System Controller 3 INT. The product is modular to expand to 40 kWh, ships now in India, and carries a 15‑year limited warranty.

Adoption depends on installers, three‑phase prevalence, and system pairing with IQ8 microinverters and the controller; warranty and LFP chemistry address safety and longevity concerns. Risks include actual field performance under high loads, installer training, and competition for three‑phase solutions. Monitor initial deployment metrics, installer feedback, warranty claims, and shipment volumes over the next 6–18 months to assess commercial traction and reliability.

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.

“India’s transition to clean, reliable energy requires storage solutions that are flexible and resilient,” said Ken Fong, senior vice president of sales at Enphase Energy. “With the IQ Battery 5P and FlexPhase technology, we are delivering a product that meets the needs of homes and small businesses in India, whether wired for single-phase or three-phase power. This launch expands on our success in other markets, and positions Enphase as a trusted partner in India’s energy transformation.”

The IQ Battery 5P with FlexPhase comes with a 15-year limited warranty in India. It can be paired with the IQ System Controller 3 INT, which together enable microgrid operation, remote monitoring, and efficient integration with IQ8™ Microinverters. With Sunlight Jump Start™, IQ8 Microinverters can restart the batteries using only sunlight after a prolonged grid outage that drains the battery. Enphase’s backup solution also supports load control and works with third-party inverters and generators for best-in-class resilience.

The IQ Battery 5P with FlexPhase is now shipping to customers in India. To learn more about the Enphase IQ Battery 5P with FlexPhase, visit the Enphase website for India.
