Solar Power Transformer Station
Product Features
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
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.
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
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
