Dual-Laderegler PWM 20A für 2 Batterien - Ladekontroller

DUAL-20A PWM solar charge controller - for two batteries from 12V to 24 volts

Up to 320 watts at 12V, up to 480 watts of module power at 24 volt battery voltage.

The charge controller is connected between the solar module and the battery and thus controls the charging process so that the batteries are 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 own current requirement (maximum 0.02A) 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.

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.
