Enphase Energy, Inc., a global energy technology company and the world’s leading supplier of microinverter-based solar and battery systems, has announced the launch of its most powerful and versatile battery yet, the IQ® Battery 5P with FlexPhase, for customers in Luxembourg. The IQ Battery 5P with FlexPhase is an all-in-one AC-coupled system that is designed to deliver reliable backup power and supports three-phase electrical system applications, which is the predominant configuration for homes in Luxembourg.

Enphase recently launched the FlexPhase battery in Germany, Austria, Switzerland. The IQ Battery 5P starts at 5 kWh of capacity and multiple units can be configured to provide up to 70 kWh. Each 5 kWh battery is designed to deliver continuous power of up to 3.84 kW in single-phase configuration and 1.28 kW per phase in three-phase configuration. The new batteries can be configured to meet the needs of each homeowner, offering grid-tied support or backup power. The batteries are designed to discharge up to two times the maximum continuous power for three seconds, enabling the start-up of high-power devices without the grid when paired with the IQ® System Controller 3 INT. The IQ Battery 5P with FlexPhase comes with an industry-leading 15-year warranty in Luxembourg.

Many homeowners in Luxembourg value flexible backup power solutions, and the IQ Battery 5P with FlexPhase meets this demand effectively. According to Cristian Hotescu, CEO of ENR LUX, a leading installer of Enphase products in the region, the battery’s scalable capacity and compatibility with three-phase systems make it an ideal choice for customers with varied home energy requirement.

Reliable and adaptable backup power solutions are increasingly popular among homeowners in Luxembourg, according to Amine M’ghari, CEO of Bauer Energie, an installer of Enphase products in the region. He highlighted that the IQ Battery 5P excels in meeting diverse energy needs—whether for self-consumption, grid support, or full backup power—while being supported by Enphase’s strong reputation for quality and reliability.

Enphase has raised the standard once again with the IQ Battery 5P featuring FlexPhase technology, according to Michelangelo Di Lorenzo, CEO of Ecosphere Home, an Enphase product installer in Luxembourg. He noted that the battery’s ability to scale from 5 kWh to 70 kWh and support three-phase configurations positions it as one of the most versatile energy storage solutions available. This high level of customization is particularly valued by customers, especially as interest in energy resilience continues to grow.

The expansion of the IQ Battery 5P with FlexPhase across Europe represents a significant milestone for Enphase Energy, according to Sabbas Daniel, senior vice president of sales at the company. He emphasized that Luxembourg is a key and growing market for solar and battery solutions, with the majority of homes built on three-phase power.

Enphase’s FlexPhase technology offers a comprehensive solution that seamlessly adapts to both single-phase and three-phase systems, while providing robust backup power and enhanced self-consumption. This development is focused on delivering greater flexibility, resilience, and value to both homeowners and installers—without compromise.
