Sungrow Launches New Energy Storage Systems for APAC Commercial & Industrial Market

Sungrow, a global inverter solution supplier for renewables, has rolled out its new energy storage system — ST129CP-50HV Series, for APAC commercial & industrial market. This product supports various applications including demand management, peak & valley arbitrage, self-consumption, power backup and micro-grid.

ST129CP-50HV Series: Providing High-quality and Economical Electricity

As renewable energy is emerging to take a large account of energy mix, consumers want to take more control of their own energy usage, and not surprisingly, energy storage has become a popular business, which is able to facilitate the new type electricity system, meet their growing demands of high-quality electricity and economical usage, and enable them to gain more profits from this new mode.

Hui Wu, Sungrow APAC account director, pointed out nowadays customers constantly face challenges from unstable grid, rising electricity price; they are concerned with the network security, difficult installation etc. Hence, observing these urgent needs, Sungrow researched and developed the new ESS solution for APAC customers.

Highly Integrated

First and foremost, ST129CP-50HV Series is a highly integrated product, says Sungrow. This series only contains two core components: the Battery Unit, integrating key devices such as battery module and heating ventilation air conditioning (HVAC); and the PCS Unit, integrating PCS, transformer, and energy management system (LC&EMS). High integration saves the space, lightens the weight, which makes the whole set product easier to be transported and installed.

Besides, the whole set adopts the uniform communication interface, namely the three-tier communications including device exchange, local control, and remote monitoring are interconnected. Furthermore, considering different consumers might have different needs for power capacity, Sungrow used modular design for this series, which supports more flexible configuration and generate larger on-grid power range from 50kW to 1MW. If you want, you can have maximum 20 units in parallel, and harvest the 1MW power.

Safe and Reliable

The outdoor cabinets of battery unit and PCS unit in ST129CP-50HV Series have high protection level and C5 anti-corrosion capability, which can sustain extreme temperature difference from -30℃ to 47℃, high sand and wind corrosion. Professional thermal design prolongs battery and PCS lifetime. Fire protection device is able to automatically and quickly detect, extinguish, quench fire and its lifetime is up to 12 years. This product is also equipped with Virtual Synchronous Generator (VSG) mode to enhance grid stability.

Intelligent and Economic

One of the greatest highlights of this series is the integrated EMS, an intelligent system developed by Sungrow, says the company. EMS can realize different functions such as demand management, peak & valley arbitrage, backup power and support micro grid. This device provides remote monitoring and O&M for customers, and thus making their using experience even more intelligent.

By using ST129CP-50HV Series, the power range is expanded, the transportation and installation is simplified, the overall security is enhanced and intelligent management also improves the system efficiency. As a result, customers enjoy decreased LCOS and increased benefits.
