Chinese manufacturer Sungrow has introduced a new utility string inverter, a three-phase hybrid inverter for commercial and industrial (C&I) applications and a liquid-cooled energy storage system.
Sungrow has developed several new products for large-scale and C&I solar projects, including a utility string inverter, a three-phase hybrid inverter and a liquid-cooled C&I energy storage system.
The new products include the SG465HX string inverter, the PowerStack ST255CS liquid-cooled C&I energy storage system and the SH125CX three-phase hybrid inverter for C&I applications.
“The latest technologies reflect Sungrow’s continued focus on system-level innovation, improved grid compatibility and practical solutions that meet evolving project and operational requirements in global energy markets,” the company said in a statement. “Our latest utility-scale and C&I technologies address real-world challenges associated with network stability, system deployment and long-term operation.”
The SG465HX string inverter has a maximum PV input voltage of 1,500 V and an AC output voltage of 1,000 V. It delivers 465 kW AC output power with a maximum efficiency of 99%. The inverter supports up to six MPPTs (Maximum Power Point Tracking Units), with six input connectors per MPPT. It is 1.19 m wide, 79.7 cm high and 40.6 cm deep, weighs 130 kg and has an IP66 protection rating.
“Designed for large-scale solar power plants, the SG465HX utility string inverter delivers high capacity and highly efficient performance while meeting increasingly stringent grid requirements,” the company said. “The solution is designed to support modern utility-scale projects with improved system reliability, strong grid adaptability and optimized levelized cost of energy (LCOE).”
The PowerStack ST255CS energy storage system has a power conversion system (PCS) with a power of 125 kW and a battery capacity of 257 kWh. It uses lithium iron phosphate (LFP) battery cells and operates over a voltage range of 691.2 V to 934.4 V. The system is 1.15 m wide, 2.45 m high and 1.61 m deep, weighs approximately 2,900 kg and has an IP55 protection rating.
“It is a fully integrated liquid-cooled energy storage system,” the company said. “The AC-coupled solution combines high reliability, advanced safety design and rapid deployment capabilities for C&I microgrid applications.”
The SH125CX three-phase hybrid inverter has a maximum PV input power of 250 kW and an AC power of 125 kW. It contains 10 independent MPPTs with two strings per MPPT and offers a maximum efficiency of 98.6%. The inverter is 1.095 m wide, 79.5 cm high and 36 cm deep, weighs approximately 128 kg and has an IP66 protection rating.
“The SH125CX enables higher solar energy utilization and more efficient energy management for commercial and industrial users,” the company said. “The SH125CX is compatible with SUNGROW’s ST255CS-S battery energy storage system (BESS), eliminating the need for a PCS in the BESS cabinet.”
