Morningstar PS-30M PWM Charge Controller

The latest generation of  Prostar Solar Charge Controllers boasts an enviable build quality and the familiar form from its predecessors, but has been updated with new data and lighting control capabilities, more advanced protection features, and a new graphical interface to perform for even the most demanding off-grid solar applications.

The Third Generation Design Features

  • Fanless design for long-term reliability
  • Three battery-level LED indicators that can be combined with an optional meter that includes safety disconnect and displays amps, volts, temperature, and self-test
  • Longer battery life through 4-stage charging and temperature compensation. Voltage-sense terminals allow for more accurate battery monitoring. Also offers constant voltage PWM series regulation.

Morningstar PS-30M PWM Charge Controller Key Features & Benefits

  • High Temperature Operation
