Solar Laderegler PWM 20A mit USB

20A solar charge controller PWM charge controller for system voltages from 12V to 24 volts

The charge controller is connected between the solar module and the battery and controls the charging process so that the battery is always optimally charged.

PWM charge controller

The current operating status is determined by a resistor and the charging process is then optimized using the principle of pulse width modulation. ua , among other things, a very low voltage drop (maximum 0.24V) and internal current requirement (maximum 6 mA) is achieved.
Therefore, PWM charge controllers are significantly more effective than simple linear charge controllers.
The built-in microprocessor charges the battery gently, thereby guaranteeing a long service life for your solar batteries.

The charge status and charging via the solar module can be seen on the LEDs. The built-in undervoltage protection prevents the battery from being discharged too much.

Overcharging of the batteries is prevented because the charge controller ends the charging process when full capacity is reached.

Suitable for acid, AGM and gel batteries . The integrated microprocessor controls the switching thresholds of the charging process precisely and temperature-stable.

Up to 280 watt module power suitable for 12V systems, up to 560 watt module power for 24 volt systems.
