The Hybrid system taken in power for Solar panel as first priority and charges battery plus supplies DC bus load demand. If Battery is deep discharged and Solar is low, it can take balance current from mains based SMPS charger simultaneously till battery gets fully charged. Thereafter it would be Solar only. In addition to it, if the battery gets discharged beyond a sattable level, set of "DG START" contact is generated which can start and stop DG set. The DG so started can be programmed to run for specified time duration of 1,2,3,4 hrs, when a "DG STOP" command will stop it. The whole equipment can be supplied upto any power and for any type of VRLA, flooded or Ni-cd Battery Bank.
