PWM SOLAR CHARGE CONTROLLER CIRCUIT DIAGRAM
This post explain about the working of pulse width modulation solar charge controller along with inverter control.
INPUT PROTECTION
: Built in
Blocking Diode to prevent SPV array from reverse polarity
and
to prevent reverse flow of current from Battery
(SPV SIDE) - Built-in
MOV protection against
HIGH VOLTAGE LIGHTNING during rainy season
CHARGING : MOSFET Based PWM Charging (microcontroller controlled)
- BOOST CHARGING
till the battery
voltage reached
14.5V
- ABSORPTION MODE to charge the battery
for 100% energy storage
- CHG. ON when PV Volt goes up 10V-11V
CHARGING LED : - LED Flash during boost nad LED constant during absorption
- LED OFF when charging
is OFF or PV Volt below 10V
LOAD CONTROL : - LOAD connector
continous active in NORMAL during Day or Night
- LOAD OFF during lo-batt
cut-off at 9.5V or 10V
- LOAD reconnect
when battery voltage goes up 12.5V or above
CIRCUITRY : - Microcontroller based electronics
- MOSFET based load control
switch and charging
switch
- PWM charging for 100% energy storage compare to ON / OFF type charge controller
