Sungrow announced its C&I energy storage system (ESS) has received the UL9540 certificate issued by TÜV Rheinland for the North American C&I energy storage market, demonstrating that this competitive ESS solution meets the comprehensive and stringent local requirements in system safety and compliance.
The ESS ST556kWh-250UD is in compliance with UL9540, UL9540A and the updated National Fire Protection Association (NFPA) criteria NFPA 855 and NFPA 70.
Optimized to the growing demand for C&I energy storage market in North America, Sungrow rolled out this all-in-one solution in September 2019 with competitive system design for energy density and low LCOE, consisting of the PCS (Power Conversion System) SC60HV, lithium batteries, energy management system, HVAC (Heating Ventilation Air Conditioning), fire suppression system and more.
Equipped with 556 kWh of Samsung SDI Mega E3 lithium batteries, the system offers cost savings with its high power density. Featuring the optimized three-level technology, the energy conversion efficiency of the PCS can also be higher. Allowing up to six units of the system to operate in parallel on the AC side makes the configuration more flexible.
Safety is the most important parameter in many customers’ minds. The E-stop function enables fast acting and arc protection for better safety management. Housed in an outdoor cabinet, the PCS and batteries are designed compartmentally. The battery compartment integrates HVAC overhead to guarantee that the battery works at a constant ambient temperature, ensuring longer battery life.
The outdoor cabinet design has a high anti-corrosion capacity of C5, the system can be resilient to harsh conditions, like coastal and high-pollution industrial areas.
“The UL9540 certified solution ST556kWh-250UD with compact design, small footprint and optimized thermal performance, guarantees minimized system operation overhead and warranty claim hassles in response to the high demand of peak shaving, frequency regulation and demand charge management,” said Hank Wang, president of Sungrow Americas. “We are delighted to bring forth more innovations to the North American storage market together with the comprehensive technical support, sales and after-sale service.”
