ZERO DROP SOLAR CHARGE CONTROLLER
PROJECT DESCRIPTION:
This circuit degisn is called ‘zero drop solar charger’ because it doesn't 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%
In this the two n channel mosfets are connected in such a way that
their sources become common and the drains will be connected to the
negatives of battery and solar panel respectively and the gate will be
triggered by the microcontroller (pic16f876a).
The positives of solar panel and battery will be joined directly and the circuit was powered from that joint.
When the solar power was present the circuit gets activated and micro-controller will pumps the signals that to trigger the gate of mosfet, when the gate was triggered the negative voltage will flow
through the mosfet and then the battery will be charged through solar
panel.
Specification:
Voltage 12v - 96v
Current 10A - 60A
Efficiency > 99.6%
Protection against : Panel reverse
Battery reverse
Battery Overcharge ( full charge cut - off level is settable )
Charger monitor - 16 x 2 lcd display
Other feature - Opto - Coupler output for Charging signal to external circuits (like inverters)

Solar energy begins with the sun. Solar panels (also known as "PV panels") are used to convert light from the sun, which is composed of particles of energy called "photons", into electricity that can be used to power electrical loads.
