Storage Beyond Limits: Hoymiles Unveils All Scenarios Energy Storage Solutions at SNEC 2025

Shanghai, June 13, 2025 — Hoymiles, a global provider of smart solar and storage solutions, successfully concluded its journey to SNEC PV Expo 2025 held in Shanghai, where the company displayed its comprehensive smart solar energy solutions under the theme “Storage Beyond Limits. Micro to Mega, All In Smart”. From residential ESS to utility-scale applications and large C&I energy storage systems, Hoymiles’ booth was a powerful demonstration of its all-in smart energy vision, highlighting the company’s ambition to expand the energy storage business across the globe.

Grid Resilience Through Scalable Storage Solutions

As the installed capacity of renewable energy continues to grow, traditional power systems are facing increasing pressure due to limited power infrastructure, bringing energy storage into the spotlight. Hoymiles’ storage solutions—known for their high reliability and strong system integration capabilities—have played a vital role in enhancing grid safety, flexibility, and stability for commercial, industrial, and utility-scale applications.

• The fully liquid-cooling HPCS2500 centralized power conversion system for grid-forming applications:

The latest PCS delivers a more comprehensive and high-performance energy storage solution. Built on ANPC topology, it achieves peak efficiency of over 99% and boasts industry-leading power density, occupying less than 1.5 m² of floor space. With intelligent liquid cooling and no derating up to 45 °C, it ensures full-power operation at 1500 V DC. Its IP65 rating and C5 anti-corrosion protection make it ideal for deployment in complex and demanding environments.

• The HoyUltra 2 (HESS-261-2h) fully liquid-cooling C&I 261kWhall-in-one battery system:

Designed for high performance and reliability, HoyUltra 2 features full liquid cooling for both battery and PCS, allowing full-capacity operation even at 50°C and 3,000 m altitude. With 90.3% round-trip efficiency and advanced safety mechanisms, HoyUltra 2 ensures 24/7 secure, intelligent performance. Its Edge EMS, cloud analytics, and local app streamline monitoring and O&M. The ultra-quiet design (60 dB) makes it ideal for noise- and safety-sensitive environments like supermarkets and residential communities.

• The high-efficiency string inverter HINV320HX-G2 320kW for ground-mountedutility PV stations:

Equipped with six MPPTs and each supporting a DC input current of up to 75A, the inverter delivers a dynamic tracking efficiency of over 99.9%. It features an SCR ≥ 0.99 and supports an SCCR of up to 0.7. With its outstanding power conversion efficiency, intelligent O&M capabilities, robust reliability design, and flexible system integration, the HINV-320HX-G2 is an ideal solution for large-scale ground-mounted solar power plants.

Residential energy storage solution to energize home energy independence

In addition to Utility and C&I PV solutions, Hoymiles’ booth also featured DIY solar & storage and residential PV and energy storage solutions, forming a comprehensive energy strategy for all scenarios.

• Micro storage MS-A2 for home DIY: It is an AC-coupled battery storage solution that works with any type of inverter to equip the home with energy storage function. With the max. output power of 1000 W and a built-in 2.24 kWh, MS guaranteesover 6000 cycles and supports time-of-use mode to deliver the best cost-effectiveness. It can be flexibly plugged into any socket with no inverter placement limits, thus providing users with great autonomy.

• Three-phase low-voltage hybrid inverter HIT-(5-20)L-G3:Covering 5–20 kW and offering 4 MPPTs, the HIT hybrid inverter boosts energy resilience with a seamless <10 ms switch between on-grid and off-grid modes. It supports 50% continuous off-grid load for single-phase systems and 200% overload for 10 seconds, powering high-surge loads like air conditioners during outages. More importantly, it features a fully upgraded installation process, simplifying inverter wiring, meter setup, and cloud platform debugging—cutting installation time by 50%.
