Solar power substation converter

Substation is manufactured as a solid metal container, equivalent to 20′ ISO High Cube container. Main advantages include high self-protection level, low weight and high logistic features. The substation presupposes an ideal solar convertor (and other electric equipment) placement that provides the best results for solar – to – electric energy conversion process, despite any negative natural conditions. Choosing mid-voltage container solar substation you’ll get everything that might be needed for effective solar energy transformation in one unit, provided in “turnkey” package.

 

Package consists of:

  • 20′ High Cube type Container
  • Solar Convertor
  • Voltage rising Convertor
  • 2L+1P circle power cable Block
  • Auxiliary Units
  • Auxiliary Converter
  • Power supplies for Converters
  • Ventilation System
  • Safety Elements
  • Warming System
