(Array to Inverter ratio 1:1), 3 phase AC Nominal Output voltade 415 V (with ±10% range), Frequency 50 Hz (±1% range), PF at rated output capacity :1 (with range from 0.8 lag to 0.9 lead), Total THD: <3%, Operating temperature range : -20º C to +60º C .Inverters should consist of associated control,protection and data logging devices and remote monitoring hardware and compatible with software used for string level monitoring all as specified and directed .Other important features/protection required in the inverter are as under :- (i) Automatic morning wake-up and nightly shutdown. (ii) Mains (Grid) over-under voltage and frequency protection. (iii)Galvanic isolation and fool proof protection against ISLANDING. (iv) Included authentic tracking of the solar arrays maximum power operation voltage (MPPT). (v) Array ground fault dectection. (vi) LCD and Piezoelectric keypad operator interface Menu deiven. (vii) Automatic fault conditions reset for all parameter like voltage, frequency and /or black out. (viii) MOV type surge arrester on AC and DC terminals for over voltage protection from lightning-induced surges. (ix) Provision for input and output isolation. (x) Inverter shall be installed on GI stand made by the angle size 50mm x 50mm x 6mm. (xi) Structure install on ground/floor and shall be 450mm above ground level. Inverter shall adjust the voltage & frequency levels to suit the Grid. Note:- Any other items not mentioned on above description but if it is technically required for optimum performance of Solar Power Plant (SPP) shall br incorporated by the contractor without any extra cost to the department.
