Sungrow Receives UL9540 Compliance Certificate for C&I Energy Storage System ST556kWh-250UD in the North American Market

Sungrow, the global leading inverter solution supplier for renewables,
announced recently that the Company's energy storage system (ESS) had
received the UL9540 certificate issued by TÜV Rheinland for 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, and forecasting more
installations that it will be involved in.

UL9540 Compliance Certificate for C&I Energy Storage System ST556kWh-250UD

As one of the world's
largest energy storage markets, North America holds the most rigid
standards for the energy storage system. The ESS ST556kWh-250UD is
completely in compliance with UL9540, UL9540A, and the updated National
Fire Protection Association (NFPA) criteria NFPA 855, NFPA 70, which are
well recognized & authoritative proof of system with high quality,
safety and reliable performance.

Optimized to the growing demand for C&I energy storage market in the North America, Sungrow rolled out this all-in-one solution in September 2019
with competitive system design for the best in class energy density and
low LCOE, consisting of the stellar PCS (Power Conversion System)
SC60HV, lithium batteries, energy management system, HVAC (Heating
Ventilation Air Conditioning), the fire suppression system and more

More specifically, equipped with 556kWh of Samsung SDI Mega E3
lithium batteries, the system can be of higher power density and
cost-saving. Featuring the optimized three-level technology, the energy
conversion efficiency of the PCS can be higher. Also, 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 and safety.

Furthermore, the outdoor cabinet design is more aesthetic in
appearance and ideally address the demands for C&I applications.
With a high anti-corrosion capacity of C5, the system can be resilient
to harsh conditions, like costal 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."

As one of the pivotal energy storage players with 23-year track
record, Sungrow is active in over 900 major energy storage projects
across the globe with zero security incidents by the end of 2019,
ranging from islands to high altitude plateaus, from ports to
residential applications. Given the cutting-edge technology, the amount
of installations as well as orders of Sungrow ESS surpassed 500 MWh in
the North America by May this year. Landmark projects include the first 1500V DC-coupled PV-plus-storage project in Florida (1.5MW/3.836MWh), and a 15MW/32MWh project in Massachusetts.
