Containerized Inverter and Transformer Substation
Product Description
The integrated inverter and transformer substation converts green energy, such as solar power, through an all-in-one inverter system and steps it up to the rated voltage for grid-connected output, significantly simplifying the PV plant architecture. The turnkey system consists of a solar inverter, busbar trunking system, low-voltage room (communication + power distribution), oil-immersed transformer, high-voltage room (equipped with a combined apparatus like vacuum load break switches + fuses, or circuit breakers), and the integrated enclosure.
