Solar Power Transformer Station


Highly integrated

■ LV panel/transformer/MV switchgear have been prefabricated and installed in a 20-feet container
■ Compact container and highly integrated design for efficient transportation and installation

Safe and reliable

■ Solid structure design and safe electrical design
■ High IP protection level for LV/MV rooms adapt to high temperature, salt, and extremely cold etc. environment

Advanced intelligence

■ Anti-PID function to ensure power generation
■ Detects the operating status of the ring main unit, transformer, and low-voltage cabinet in real time.
■ Smart communication box which integrates Anti-PID, PLC, data logger for fast networking of the PV plant.

Fast deployment and lower cost

■ Standardized 20-feet container for fast deployment and easy installation
■ Cables between internal equipment have been connected, only LV cables, MV cables and communication cables to external equipment need to routed out onsite
