| 76 | Design, Supply and installation of Solar Grid Connected inverter of capacity 1500 KW or nearest available capacity on higher side, 3 phase, 440 Volt, AC operated, 50 Hz,indoor type including supply and fixing of suitable String combiner box with following features completeall as specified and as directed:- |
| 77 | (a) For initializing the inverters from the sleep mode, it is important that there is sufficient sunlight and that the utility grid is available. Sufficient sunlight in the morning is needed to provide adequate power to the inverter so that it could start up from the over night sleep mode. Availability of the Grid is required to the inverter as it has been programmed to a logic and a pre-set window of Grid voltage and frequency. If the available Grid has all these qualities for which the inverter is designed, it would initialize the main out put contactor and couple with the Grid and start evacuating the power to the Grid it is coupled with. In case the Grid fails due to any reason, the inverter should come to idle mode till the Grid comes back again. Even during the power evacuation, if the sun light falls below the desired limit, due to clouds etc., the inverter also stops working, although the Grid is available, till it starts getting the desired solar power required to power the inverter it self. |
| 78 | (b) If the power evacuation goes on till the evening the inverter should keep on getting the desired solar power which is in excess of the power needed to operate the inverter itself. As soon as it attains the power which is just sufficient to run the inverter, the power evacuation stops and only the inverter keeps running till the power drops further low due to decreasing sunlight in the evening, resulting in the inverter going to sleep mode to initialize again automatically the next morning.(c) A record shall be maintained with input from inverter in the event of failure of the utility grid resulting in inverter going to sleep mode and stop generating power. |
| 79 | (d) The Power Grid should have the following salient features:-(i) The PCU shall be made in India. The PCU / inverters should be tested from the MNRE approved test centres / NABL / BIS / IEC accredited testing-calibration laboratories.(ii) The charge controller (if any) / MPPT units environmental testing should qualify IEC 60068-2 (1, 2, 14, 30) / Equivalent BIS standard.
