PWM controller

PWM solar regulators ensure that your batteries are charged correctly by adjusting the operation of the panels to match the voltage of the battery bank. They are suitable for many uses (residential, agricultural, industrial) when a simple, reliable and robust solution is required.

To choose your model, first check the battery voltage ( 12V/24V) and then size the current (in A) according to your panels and your needs. Depending on the installation, you can add a control system (screen/remote control) to facilitate monitoring.

AGM/GEL batteries
Lithium batteries (LiFePO4)

Choose in 30 seconds

  • Battery voltage: check 12V / 24V depending on your battery bank.
  • Current: select the amperage (e.g. 10A, 30A) according to your panels and your needs.
  • Control: if necessary, add a display (e.g. MT50) or a remote control (e.g. CU-ALL5).
  • Use: residential, agricultural or industrial: choose a model suited to the expected robustness.

FAQ - PWM solar charge controller

1. What is a PWM solar charge controller used for? +
A PWM controller is used to charge batteries properly from solar panels by matching the battery bank voltage (e.g., 12V/24V) for durable solar energy use.
2. How do I choose between 12V and 24V? +
Choose based on your battery/battery bank voltage: pick a controller compatible with your system (12V or 24V).
3. How do I size current rating (10A, 20A, 30A)? +
Size in amps based on your panels and needs: higher charging current requires a controller with a suitable current rating (e.g., 10A or 30A).
4. Can I add a display or a remote control? +
Yes, depending on the model: you can add a display (e.g., MT50) or a remote (e.g., CU-ALL5) for easier monitoring/control.
5. Which batteries are these controllers used with? +
It depends on the system and charge settings. For storage options, see AGM / GEL batteries and lithium batteries (LiFePO4).
