Swatten, a subsidiary of Sieyuan Electric Co., Ltd., presented its latest energy storage solutions at the Key Energy 2025 exhibition in Rimini, Italy, from March 5-7, 2025, at booth D5-210. We unveiled two new products—the Single-Phase Hybrid Inverter (8/10kW) and the All-In-One System (5-20kW)—while highlighting its flagship Three-Phase Hybrid Inverter (10-50kW) and its versatile applications.
In 2024, Sieyuan Electric Co., Ltd. achieved a revenue of over US$2.3 billion, with a 22% year-on-year growth, ensuring its position as a top player in the power industry. Sieyuan Electric has served the Italian market for over a decade, partnering with major clients such as ENEL, ENI Plenitude, STE, STACK, SIMIC, and SUNNERG.
Swatten, backed by its strong product capabilities, is committed to providing reliable and green power solutions for households and businesses across Italy.
The Italian energy storage market saw a significant increase in installed capacity by 5.9GWh in 2024, with over 730,000 operating systems, primarily residential systems under 20kW. As demand for commercial and large-scale storage systems above 20kW is expected to grow, Swatten's Three-Phase Hybrid Inverter (10-50kW) is designed to meet this need. It supports up to 30 units in parallel for a maximum output of 1.5MW and is adaptable to 3MWh of battery capacity. This makes it ideal for high-load applications in factories, agricultural facilities, and commercial buildings. The system also supports 1.8MW of photovoltaic integration, enabling efficient "solar + storage" solutions.
Key features of the Three-Phase Hybrid Inverter include a maximum 16A photovoltaic input current and 20A short-circuit current, ensuring compatibility with most solar panels and high efficiency. The 3-string, 6-MPPT design supports 200% oversizing, improving energy efficiency and enabling high-power, multi-orientation installations for optimal performance. With a low starting voltage 150V and a wide MPPT voltage range (150V-950V), the inverter ensures earlier startup and longer operation in challenging weather conditions. It also offers 50/60/65A charging current for fast battery charging and emergency power supply, supports whole-home backup, and integrates EV charging for a complete solar-storage-charging system, suitable for virtual power plant (VPP) scenarios.
Italy is a key solar and energy storage market, so Swatten has successfully showcased its latest innovations at Key Energy 2025. We also successfully hosted our Three-Phase Hybrid Inverter presentation, highlighting its advanced features and benefits.
A huge thank you to everyone who joined us—we appreciate your support and enthusiasm!
