Our specialty is custom charger units.

Hybrid battery charger circuit.

The charging discharging current will be no more than 1 5a i want to use an arduino uno to modulate mosfet s using the controller via pwm to charge the main hybrid battery. Opamps lm358 or any similar. T1 t2 tip142 t3 bc547. 2 shows circuit for the hybrid solar charger which is built around a 12v 10w solar panel connected at sp1 operational ampli fier ca3130 ic1 transistor bc547 t1 12v single changeover relay rl1 step down transformer x1 and a few other compo nents.

60hz 50hz 200vac you name it. R1 r2 r3 r5 r6 10k. Contact us for details. Circuit and working fig.

We have now shipped more than 75 units. The diode d1 provides reverse polarity protection and capacitor c1 buffers voltage from the solar panel. Op amp ic1 is used as a simple voltage comparator. Z1 z2 3v or 4 7v 1 2 watt zener diode.

Connect the circuit to the solar panel and measure the input voltage. Parts list for the solar wind dual hybrid battery charger circuit. Make sure that it is above 18 volts. Hybrid solar charger circuit working in sunny sunlight the 12v 10w solar panel delivers up to 17 volts dc with the 0 6 ampere current.

D1 10 amp rectifier diode or schottky diode. The nominal voltage is circa 235vdc which can peak at 250vdc. Double dc input hybrid charger circuit.
