ProStar PS15 PS30 PS15M

Morningstar's ProStar Solar Charge Controllers Logo

By using highly advanced technology, this second generation ProStar sets new standards for reliability and self-diagnostics. It also provides several unique features and protections. And Morningstar's patented PWM battery charging has been further optimized for longer battery life and improved system performance.

The ProStar is available in 15 or 30 amps, 12/24 or 48 volt, and negative or positive ground. The controller may be paralleled for a solar input rating of up to 300 amps.

  • Self-diagnostic test provides assurance the controller is working correctly, or indicates a fault
  • Simple and positive selection of battery type
  • Pushbutton disconnect for load and solar panels
  • Five protection functions are displayed in the digital meter
  • Meter indicates "OFF" if solar or load is disconnected
  • PWM is indicated in the green battery status LED (blinking)
  • built-in temperature sensor to read ambient conditions more accurately
  • solar short circuit and overload protection / auto recovery
  • load overload protection / auto recovery
  • load short circuit protection / auto recovery
  • protection of the load from voltage spikes
  • low battery voltage and brownout protection / auto recovery
  • Extensive digital filtering for improved accuracy
