Power Conditioning Units (inverters) are deployed to convert the electricity from DC to AG. The inverter output is further stepped by outdoor transformers, Power generated is exported to transmission grid. The various electrical panels such as inverters, circuit breakers (VCB), ACIDC distribution boards, UPS panels etc. are housed in 11 nos. rooms. Among these, 10 nos. are inverter raoms of PEB type for which foundation up to plinth level is of ROCstructure and above plinth, PEB steel structures! sheets shall be used for construction. Generation from each PEB inverter room is SMWp. Thus, all 10 nos. inverter rooms collectively generate 45MWp. In addition to the Inverter rooms, the security room (~4 sam) is also of PEB type, The 10 nos, PEB inverter rooms are located at distributed locations within the power plant. ACoutputs from all these rooms are combined at CMCSraom, Security room islocated near the entrance gate.Doc.
