Electric electronic apparatus for Vessel & Industrial plant facility, Solar module manufacturing development
ESS (Energy Storage System) consists of MPPT-based DC-DC converter., bidirectional DC-DC converter, bidirectional inverter and batter.
DC power generated by solar module and AC input power supplied form grid are consumed in the load as well as stored in the battery/
By storing the surplus energy, the ESS can supply the energy when it is needed. Therefore, the ESS can play a role on UPS
