Solar Charge Controller has many built in features to prevent short circuit, over-load. With the built in 3-stage PWM charging algorithm the Solar Charge Controller will protect your batteries from over charging and will ensure the charging is optimised for a longer battery life.

Only suitable for Lead Acid Batteries. Not to be used with Gel or Lithium Batteries.
Simple to use and easy to install.

PWM (Pulse Width Modulation) is not as efficient as a MPPT Charge Controller because a PWM controller will only adjust the voltage from the panel to match the battery voltage while keeping the amps from the panel the same. A MPPT controller will convert the total power of the panel (voltage and amps) to charge the battery.

Example : MPPT vs PWM for a 12V system using a 100W solar panel 18Volts x 5.55Amps
PWM: 12V x 5.55Amps = 66.6W - Voltage decreased from solar panel and Amps remain the same
MPPT: 12V x 8.33Amps = 100W - Voltage decreased from solar panel and Amps increased
