TECHNICAL SPECIFICATION

The Grid Connect Solar Power Generating System consists of mainly three components viz. the SPV (SPV)

array, module mounting structure and the power conditioning unit (PCU)/ inverter. The SPV array

converts the solar energy into DC electrical energy. The module mounting structure holds the modules in

required position and the DC electrical energy is converted to AC power by the PCU, which is connected

to the power grid. The AC power output of the inverter is fed to the AC distribution board through

metering panel and isolation panel. The 415 V AC output-3Ø of the system can be utilized or as an option

it could be stepped up to the required voltage level and after synchronizing with the grid, can be

exported to the grid.
