Hoymiles, a global leader in smart solar and storage solutions, made a standout appearance at Intersolar Europe 2025, showcasing its diverse portfolio of energy storage systems for various applications, from DIY micro-storage to utility-scale solutions. The company’s exhibition was centered around the theme “Storage Beyond Limit. Micro to Mega, All In Smart,” reflecting its drive to push the boundaries of energy storage technology.
HoyUltra2 Series: Next-Generation Commercial and Industrial Storage
At the core of Hoymiles’ exhibition was the HoyUltra2 series (HESS-261-2h), a next-generation energy storage solution for commercial and industrial (C&I) applications. Featuring an advanced liquid cooling system for both the battery and power conversion system (PCS), HoyUltra2 ensures full-capacity operation even in extreme conditions, such as 50°C ambient temperatures and altitudes of up to 3,000 meters.
With a maximum round-trip efficiency of 90.3%, HoyUltra2 incorporates a robust six-level safety protection mechanism, ensuring secure and intelligent 24/7 operation. The system’s Edge EMS offers local optimization, while the cloud-based analytics provide deep system insights. Designed for quiet operation (60dB) and built to withstand harsh conditions with an IP55 rating, HoyUltra2 is ideal for applications such as supermarkets, hotels, and residential communities.
HoyPrime Series: High-Efficiency, Safe Large-Scale Storage Solutions
Hoymiles also introduced its HoyPrime containerized storage solutions for large-scale C&I and utility applications. Available in 1 MW/2 MWh configurations for commercial projects and 3.44 MWh for utility-scale solutions, HoyPrime offers high energy density, cost-effectiveness, and intelligent liquid cooling to minimize power consumption and extend the system’s lifespan.
With a compact, non-walk-in design, HoyPrime maximizes capacity while reducing the physical footprint. The system features standardized interfaces and automated maintenance for easy deployment and operation. Certified to IEC and UL standards, HoyPrime is already operational in projects across the globe, strengthening Hoymiles’ position as a global leader in energy storage.
