Supply Of The Under-Mentioned Goods/Articles -Solar Battery Testing Unit -Components and Specifications of the Unit a) Battery - 12Volt,7.2 A-Hr sealed maintenance free Lead Acid battery - 3 nos. (Exide make) b) Solar Cell – Polycrystalline Solar Panel 50 Watt, 12 Volt - 01 no.(Exide make) c) Variable dc discharge controller - 3 channel (one for 0 to 2 volt and another two for 0-6 Volt & 0-12 Volt respectively) with metering device for Voltmeter, Ammeter d) Solar charge controller - It comes with LCD display which clearly indicates the battery charging status, conveniently switched modes and (1) parameter configuration with 2 front USB for 5V operation (2) Solar charge controller work with 12v panel, one can set Float voltage, Discharge reconnect, Discharge stop and work mode (While setting hours setting the load ON after sunset automatic). (3) It should have Reverse protection, Overcharge protection & Over circuit protection. (4) It should have selectable Float voltage, Discharge reconnect and Discharge disconnect voltage output settings and load ON/OFF button. It should have built in timer for 24 hrs. This Solar charge controller is specific for lead acid batteries: OPEN, AGM, GEL, not for nickel hydride, lithium, Li-ions, or other batteries. Dimension is approx. L X W X H = 150 X 8 X 4 cm – 01 no e) Multichannel Battery Charger – In absence of solar radiation battery can be charged through this charger (12/24 Volt,10A) from standard ac power supply – 01 no f) PC Based Battery Testing System (with data logging facility) for a single Lead Acid Maintenance free battery –In this system each test is identified by a Test name, supplied by the user. The software running in the PC/Laptop communicates with the micro-controller based front-end hardware to collect the voltage, current and temperature data. It also applies the load to the battery as programmed by the user. Each test data is stored against the test name, so that old test data can be retrieved later to generate graphs and reports. The program should generate one tabulated report of voltage, current and temperature of the batteries in periodic interval selected by the user. The report includes the calculated battery life for different values of cut off voltage points. These cut off voltages should be user defined. The program also generates the discharge curves for the battery under test as well as the average of them. – 01 no g) Solar cell Frame making, equipment installation, wiring from rooftop to laboratory, labour cost.
