PWM Solar Controllers

Shop PWM solar charge controllers for simple matched-voltage 12V and 24V battery-charging systems. PWM controllers provide a cost-conscious option for smaller solar setups where the panel voltage is appropriate for the battery-system voltage.

PWM Solar Controllers for Basic 12V & 24V Charging

This collection includes 10A and 20A PWM solar charge controllers. These are best considered for smaller systems after confirming the panel current, battery voltage, battery chemistry and controller specifications.

When a PWM Controller May Suit

  • Matched-voltage panels: a practical choice where the solar-panel voltage closely matches the 12V or 24V battery system.
  • Smaller solar arrays: check that the array current remains within the controller’s stated 10A or 20A rating.
  • Budget-conscious systems: PWM controllers can be a straightforward option for basic compatible charging applications.

Important Checks Before Buying

  • Confirm your battery-system voltage and chemistry are supported by the controller.
  • Check the solar panel’s rated current and open-circuit voltage against the controller limits.
  • Use suitable cable, connectors and fuse protection for the planned current.
  • For larger arrays, higher-voltage panels, longer cable runs or more complex lithium systems, compare an MPPT controller instead.
