M.P.P.E. and Zero Drop Charge Controller Circuit :
We know that solar pv is a constant current source whose output depends on direct sun light. The solar pv output is given to M.P.P.E. (maximum power point extraction) circuit or Zero drop charge controller (fixed P.W.M.) circuit. These circuits are designed to deliver maximum rated charging current to the battery / D.C. load. The voltage across the solar panel goes on reducing when maximum power is extracted from it. M.P.P.E. or Zero drop charge controller circuit adjusts the perfect balance between solar panel voltage and current flowing through it in such a way that maximum power can be delivered to the load. Easy select switch can be used to select ups or inverter mode.
The D.S.P. based M.P.P.E circuit continuously varies P.W.M. duty cycle to deliver maximum power to the load by perfectly matching impedance between solar panel and the load that ensure 25% to 35% more power can be delivered to the battery / D.C. load. A special type thick plate deep discharge battery (C 10) type is used for solar applications.
Lead acid battery may produce hydrogen gas which is highly explosive .So, for precaution, always keep U.P.S./ Inverter and it’s battery at least 1 meter away from each-other and away from fire and short circuit prone situations at ventilated place only and at 25oC or below.
Inductive loads such as motors, house hold mixer grinder, heaters, irons etc may take three times more power while switching on than the required power for normal operation so while selecting Inverter for such application one should consider this and must keep in mind that inductive load consumes more power than other type of loads and also battery drains at a faster rate.
