Minimum Requirement and specification for on grid inverter :- (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. (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. (d) The PCU / Inverters should be tested from the MNRE approved test centres/NABL/BIS/IEC accredited testing-calibration laboratories.+C50:C59C50:C61C50:C62C50:C61C50:C60C55C50:C57C50:C59C50:C60C50:C61 (e) Inverter Manufacturer should supplied and installed minimum of 10 MW cumulative capacity of inverter in last 5 years in India (f) Minimum efficiency 98.5%. (g) The DC to AC ratio not grater than 1.25 is to be maintained at all sites. (For eg. – For DC capacity of 100 kWp, the AC capacity of minimum 80 kW is to be maintained). (h) The PCU shall have a higher degree of ingress protection of IP 65 to handle robust environment conditions from dust and water ingress under complete outdoor installations. (i) The data logger should possess the feature of extracting the data externally with open protocols like Modbus TCP/RTU. The manufacturer should provide the Modbus register mapping file to utilise this feature (j) Specifications: (i)Nominal voltage - 680 to 880 V (ii)Voltage Band - Between 80% and 110% of V nominal, pollution degree-IV (ii)Nominal Frequency - 50 Hz safety class (iv) Operating Frequency Range - 47.5 to 50.5 Hz (v)Waveform - pure Sine wave (vi) Harmonics -AC side total harmonic current distortion < 3%
