PWM Solar Controllers

PWM (Pulse Width Modulation) solar charge controllers offer a reliable and cost-effective solution for smaller solar installations. By regulating the voltage and current flowing from your solar panels to your battery bank, a PWM controller prevents overcharging, reduces battery stress, and extends overall battery lifespan.

Ideal for caravans, campervans, boats, and off-grid cabins where system simplicity and affordability are the priority. PWM controllers work best when the solar panel voltage is closely matched to the battery bank voltage — making them a practical choice for straightforward 12V and 24V systems with panels in the 100W–400W range.

For larger or more complex solar installations where maximum energy harvest is required, an MPPT (Maximum Power Point Tracking) controller will typically deliver better performance. However, for everyday recreational and light off-grid use, a quality PWM controller provides dependable protection and charge management at a lower cost. All controllers are stocked in Australia with nationwide delivery available.
