Spotlight on next-generation C&I storage: HoyUltra2
At the heart of Hoymiles’ exhibition is its next-generation commercial and industrial storage solutions, led by the new HoyUltra2 series. Engineered for maximum performance and reliability, HoyUltra2 (HESS-261-2h) features a fully liquid cooling design for both the battery and PCS components, allowing for full-capacity operation without derating even at the ambient temperature of 50°C and at the altitude of 3,000 m.
With a maximum round-trip efficiency of 90.3% and an industry-leading three-level, six-type safety protection mechanism, HoyUltra 2 ensures 24/7 secure and intelligent operations. Its edge EMS enables local optimization, while cloud-based analytics provide powerful insights for system management. Integrated with a user-friendly local app, HoyUltra2 simplifies O&M tasks, promoting efficiency at every stage. The quiet operation at 60dB and IP55-rated protection make it suitable for supermarkets, hotels, residential communities, and other sensitive environments.
High-efficiency and safe large-scale storage: HoyPrime series
Hoymiles introduces its HoyPrime containerized storage solutions, available in 1 MW/2 MWh for large C&I projects and 3.44 MWh for utility-scale applications. Designed for cost-effectiveness, high energy density, and operational efficiency, the HoyPrime series features intelligent fully liquid cooling to minimize auxiliary power consumption and extend the system’s lifespan. The compact, non-walk-in design significantly reduces footprint while maximizing storage capacity.
Prioritizing safety, HoyPrime offers comprehensive cell monitoring, multi-level protection, and advanced fire suppression for rapid thermal runaway response. Standardized external interfaces simplify installation, while automated maintenance features such as coolant replenishment and SOC calibration reduce downtime and boost lifecycle performance. Supporting various grid protocols, HoyPrime enables 100 MW-level source parallel operation for grid stability. Certified to IEC and UL standards, it has been successfully deployed in multiple countries, reinforcing Hoymiles’ leadership in the global energy storage market.
