Supply, Installation and Commissioning of 50KWp Rooftop Solar Photovoltaic Power Plant without battery backup on turn-key basis at Integrated Check Post (ICP), Akhaura Road, A
CU ( Power Conditioning Units)/ INVERTER: As SPV array and also battery bank produce direct current electricity, it is necessary to convert this direct current into alternating current and adjust the voltage levels to match the grid voltage. Conversion shall be achieved using an electronic inverter and associated control and protection devices. All these components of the system are termed the “Power Conditioning Unit (PCU)”. In addition, the PCU shall also house MPPT (Maximum Power Point Tracker), an interface between Solar PV array & the Inverter to maximize energy drawn from the array. The power conditioning unit / inverter should also be interactive with battery bank with appropriate control mechanism for charging the battery bank from the SPV array and optionally from grid (for the SPV power plant with battery back up). Inverter output should be compatible with grid frequency. The power conditioning unit should be grid ready i.e., it should have the facilities to be grid interactive as and when required for export/import of power to/from grid.
