    Morningstar ProStar Gen3 PWM Charge Controllers

    The ProStar solar charge controller has been the leading mid-range pulse width modulation (PWM) controller since 1995. With over 350,000 units installed in the harshest environments in over 100 countries, the ProStar has developed a strong reputation for reliable performance. This third generation ProStar maintains the same quality and form factor as previous models, while offering new data, lighting control, graphical interface, and protection features to better meet the needs of off-grid solar applications.


  • High reliability – latest electronic and environmental protections, quality control, and design considerations comply with IEC 62109 and promote longevity in the harshest environments

  • High Temperature Design – full nameplate current rating, both solar and load up to 60°C continuous.

  • Auto-battery-select – 12V and 24V systems.

  • Data Logging – up to 256 days of solar charge and load consumption data.

  • Low Noise Design – meets US Federal Communications Commission Class B specifications

  • Automatic Solar Based Lighting Control – field adjustable, multi-event load control enables powerful options for solar lighting systems

  • MODBUS Communications – open standard MODBUS communications protocol allows for control and remote data access.

  • Durable Design – high strength polycarbonate case with protective terminal cover and extruded aluminum heatsink.

  • Self Diagnostics – continuous monitoring and reporting of any errors or system faults through its status LED’s, optional display and communication port.

  • Meter – high resolution LCD, multi-lingual backlit graphical display of system voltage, current, temperature, lighting settings, etc.
