CE FCC certification pwm Solar Charger Controller 20A 12V/24V ONE controller

Model :?PWM-20124

?

The controller is for off-gird solar system and control the charging and discharging of the battery.

Main function is protecting battery. The intelligent charging process has been optimized for long battery life and improve system performance.

?

?

The load control mode can be selected, the timer function can be reset for street light at night.

Reliable over voltage protection, short circuit, over load protection, overcharge protection, over-discharge protection.

Accurate temperature compensation, correcting the charging and discharging voltage automatically, improving the battery lifetime.

Roundly reverse connected protection.

Solar panels, battery, solar charge controller positive poles are all connected together, adopting negative MOSFET in series control circuit.
