The container-type compact substation is a dedicated power distribution unit for wind and solar farms. It steps up the low-voltage output from inverters to 40.5 kV for grid connection. Housed in a standard shipping-container enclosure, it offers modular design, small footprint and easy on-site installation — ideal for large-scale renewable energy projects.
