Monitoring: Each distribution point has an energy meter. Data is logged to a central server so the school can see generation and consumption data. If one section of buildings consumes extra load this is seen and can be prevented. If required, building level monitoring can be provided for specific auditing. 50 Panels mounted on custom built MMS over battery room PCU 120 numbers of 2V, 300Ah batteries on two racks Control panel with data monitoring 3ph Grid Input 1ph AC Output on 4-core UG cable PV input Distribution Boxes Power consumption from each distribution box is measured and logged
