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, ProStar sets the standards in performance and reliability for the rest of the solar industry.

The Generation 3 ProStar shares the outstanding build quality and familiar form factor of its predecessors and adds data and lighting control capabilities, a graphical interface, and advanced protection features that meet the needs of today’s most demanding off-grid solar applications. ProStar provides both “the legend and the latest” in a single new product.


  • 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 Operation: 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

  • 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

  • Custom Programming: Dip switches, meter interface, or connection with a computer can be used to adjust charging, load communications, and lighting control

  • 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
