Hoymiles Expands Into the European Solar Market with Hi Series

On September 22, 2025, Hoymiles, a global provider of smart solar energy production and storage solutions, launched its innovative Hi series in Germany. This series includes not only compact and highly efficient microinverters but also the HiBattery AC, a safe and affordable energy storage system. With an emphasis on empowering households to achieve true energy independence, Hoymiles aims to make sustainable energy accessible and straightforward for everyone.

Shift Towards Self-Consumption in the European Solar Sector

The European solar energy market is evolving, moving away from subsidies and focusing on self-consumption and energy autonomy. Hoymiles understands this shift and has adapted its product offerings accordingly. The Hi series represents a significant leap in solar technology, combining easy-to-use components with exceptional pricing. This aims to enable households worldwide to harness solar energy effectively.

Introducing the HiFlow Microinverters

The HiFlow series, comprising HiFlow and HiFlow Pro models, is built on over a decade of research and development, resulting in numerous patents. The HiFlow 800 model is specifically designed for compact photovoltaic systems, making it ideal for small rooftops, balconies, and garden installations. It achieves a maximum efficiency of 97% and can be set up in under a minute using Hoymiles' S-Miles Home app for real-time monitoring and control.

The HiFlow Pro is tailored for more complex scenarios. It features advanced energy conversion algorithms and can achieve efficiency levels of up to 99.8%, ensuring optimal power output even in shaded conditions or complex panel arrangements. The Pro series accommodates nominal power ratings from 300W to 2000W, addressing a wide variety of installation needs.

HiBattery AC: The Flexible Energy Storage Solution

In addition to microinverters, the HiBattery AC is Hoymiles' solution for micro-storage coupled with alternating current. Designed with safety and simplicity in mind, this system integrates automotive-grade LFP (lithium iron phosphate) cells, offering a lifespan of over 6,000 cycles alongside a battery management system featuring 48 layers of protection, advanced internal extinguishing capabilities, and a pressure relief valve. Its unmatched bidirectional efficiency of 96.5% and round-trip efficiency of 86% makes it an outstanding choice for households seeking reliable energy storage.

Unlike complex hybrid systems that require costly inverter replacements, the HiBattery AC is ready to plug into any standard outlet, eliminating the need for rewiring and allowing for versatile placement within the home. Its bidirectional technology also facilitates time-of-use pricing when supported by smart meters, enabling users to charge during low-cost periods and discharge when rates are higher, maximizing savings and returns.

The HiBattery AC is compatible with all market inverters, but it truly shines when paired with Hoymiles' HiFlow and HiFlow Pro microinverters, offering comprehensive power control and zero-export functionality. This system can operate off-grid, providing reliable backup power during outages, or function as a portable energy source for camping and recreational vehicles.

Commitment to Accessible, Clean Energy

Yang Bo, the CEO of Hoymiles, emphasizes that energy transition should not be reserved for specialists or privileged users. The Hi series is designed to bring professional-grade solar technology within reach for all households, whether they are setting up a simple balcony system or a complex rooftop array. Hoymiles is committed to 'open energy for all,' striving to make clean, reliable energy accessible to every household.

As the world's leading supplier of microinverters (excluding the U.S. market) in 2024, Hoymiles is already powering over a million European balconies. The Hi series is more than just a product launch; it marks Hoymiles' dedication to enhancing clean energy adoption across Europe, beginning in Germany and expanding throughout the continent. This initiative is central to the vision of a sustainable energy future for all.
