TSTY Integrated Renewable Power Stations are a complete range of prefabricated compact substations specifically engineered for solar, wind, and battery energy storage systems. Designed to simplify grid connection for renewable energy projects, these integrated units combine step‑up transformers, medium voltage switchgear, low voltage distribution, and optional power conversion systems (PCS) into a single, factory‑prefabricated enclosure. They accept low voltage AC input from PV inverters, wind turbines, or bidirectional PCS from battery storage, and step up to medium voltage levels (10kV, 20kV, 33kV, 35kV or 66kV, etc.) for reliable grid interconnection.
Our product family is divided into four specialized series to match specific renewable applications:
PV Inverter Step-Up Substation – For utility‑scale and commercial solar farms.
BESS Step‑Up System – For grid‑scale and C&I battery energy storage with bidirectional PCS.
Wind Power Compact Substation – For onshore wind turbines, resistant to vibration and extreme climates.
New Energy Prefabricated Substation – Modular cabin and Huashi type for flexible deployment (EPC, mining, emergency).
All TSTY units feature IP54/IP68 protection, C4/C5 anti‑corrosion coating, intelligent remote monitoring, and are CE, IEC, UL, ISO, SASO‑certified. With over 30 years of manufacturing experience and deliveries to 80+ countries, TSTY provides turnkey, weather‑resistant, and grid‑ready solutions that accelerate renewable energy integration worldwide.
New Energy Compact Substation: Photovoltaic & Energy Storage Step‑Up Unit
Our New Energy Compact Substation, also known as a photovoltaic step‑up substation or PCS turnkey integrated unit, is specifically designed for solar farms, battery energy storage systems (BESS), wind power plants, and other renewable energy applications. Unlike conventional distribution substations, this unit combines a step‑up transformer (oil‑immersed or dry‑type), high‑voltage switchgear, low‑voltage distribution panel, and an optional bidirectional power conversion system (PCS) into a single, fully enclosed enclosure.
The substation accepts low‑voltage AC output from PV inverters or from battery storage systems via a PCS, and steps it up to medium voltage levels such as 10kV, 20kV, 33kV, 35kV, or 66kV for direct grid interconnection. It also supports reverse power flow for battery charging, making it ideal for peak shaving, load shifting, frequency regulation, and renewable smoothing.
Available in skid‑mounted, containerized, or pad‑mounted configurations, the unit requires minimal on‑site civil work, reducing installation time by up to 50% compared to traditional stick‑built substations. The weatherproof steel enclosure provides IP54 to IP65 protection, with anti‑corrosion coating rated up to C5‑M for coastal or desert environments. Key features include mechatronic integration, fully enclosed operation, low noise, and maintenance‑free design.
All TSTY new energy compact substations comply with ICE, IEC, UL, ISO, SASO-certified. Typical applications include utility‑scale solar farms (10MW to 100MW+), containerized BESS projects, industrial solar‑plus‑storage, wind power collector stations, remote microgrids, and EV charging hubs with on‑site solar
