Umar And Son's low cost zero drop solar chargers are available in various ranges 12V to 96V and 5A to 80A which is compatible with Umar And Son's inverter design and can be used with other inverter designs as well.
These chargers are called 'zero drop solar chargers' as they do not have any diode drop of 0.7V. This is a MOSFET based design which has very negligible voltage drop of 0.05V or less which means the loss is very less, ideal for solar applications. Since the drop is less, the losses are negligible so the efficiency achieved is > 99.5%.This is a micro-controller based charger, the micro-controller will sense the battery full charge voltage and will cut-off the battery when it reaches full charge. It will reconnect the battery if the battery drops to a preset level. The charger will also disconnect the panel from the battery, this is to avoid the reverse current flow from the battery to the panel during night. Moreover, if you connect the panel reverse, the micro-controller will not switch on the charger, similarly if you connect the battery reverse, the charger will not function. Battery reverse and panel reverse protections are incorporated in the design. If you connect both panel and battery reverse at the same time, the micro-controller will not switch on the charger. In all the above cases, the circuit will not damage and there will not be any current flow from the panel or battery.
