Solar Rooftop Tenders

W.R.I D.D. Schedule of Rates 2021,ch. 12, item no. 3/b Power conditioning unit with IP54 enclosure: Supply , transport,Installation and commissioning of IP 54 protected enclosured inverter unit qualifying IEC 61683 Efficiency measurement and IEC 60068-2 environment standard suitable for 3 phase A.C. motor, IGBT based high voltage switching inverter with MPPT technology, to take care of the varition of sun light and will be suitably mounted inside the metal enclosure. Inverter should have protection against dry run, over current, under current, over voltage, under voltage, short circuit etc.system should be able to run at low sunss a day run should be possible during normal sunshine condition inverter should have option to auto start trip off due to low light/cloudy situation except for dry run. Inverter should be provided with a display to show the various parameter by the user such as voltage, current, solar panel DC voltage, Inverter IGBT tempreture, out put AC voltage, output frequency, pump flow ( direct or calculated method), Irradiation ETC. The system should store the data at a set interval, be capable to transfer it to external storage device and support communication of its operational parameter and logs over modbus protocol it should also monitor and save total run time, total water pumped etc. there should be provision for interfacing GPRS based data transmission Amrit/Havels/Suriya or equvalent. B) For 1 HP capacity pump motor set.(As per direction of EIC) ( as per Govt approved)
