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
