Solar Low drop Charge controller

SOLAR CHARGER CONTROLLER

Our low cost low drop solar chargers are available in various ranges 12V to 120V and 5A to 80A  can be used with other inverters available in the Market .These chargers are called 'Low drop solar chargers' As they Have Very Less Components  the chance system failure is almost nill .

This is a MOSFET based design which has very negligible voltage drop which means the loss is very Low, 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. In all the above cases, the circuit will not damage and there will not be any current flow from the panel or battery. The design has opto-coupler based signal sensing which makes it completely isolated and there will be no grounding issues. Two stage higher voltage regulator is incorporated in this design to withstand open circuit voltage of the panel.

The Technology cost will be Rs 10,000/-
