Product Details

Universal Go Power™ Digital Solar Controller (GP-PWM-30) by Carmanah®. To stop the battery from being overcharged by the solar module, a solar controller (sometimes referred to as a solar regulator) is connected between the two. Go Power!'s GP-PWM-30 controller will disconnect power from the solar module when the battery is fully charged. Once the battery voltage drops by approximately one volt, the controller will resume charging.



  • Faster to install, more accurate and user friendly
  • Automatically adjusts for 12 or 24 volt solar systems
  • Three battery charging profiles for Gel, AGM, and Flooded batteries with longer boost function.
  • Protects batteries from over temperature and over voltage
  • Reverse polarity protected - eliminates user failures
  • Improved 4-stage charging: Bulk, Float, Absorption and Equalize
  • Pulse Width Modulated charging – Produces more charging power out of solar modules
  • Max wire size up to #6 AWG
  • Push-button operation
  • Five-year warranty

A Charge controller is an essential component of your photovoltaic (PV) system. The controller maintains the life of the battery by protecting it from overcharging. When your battery has reached a 100% state of charge, the controller prevents overcharging by limiting the current flowing into the batteries from your solar array.

The NEW GP-PWM-30 is a 12 volt flush mounted PV charge controller rated for a continuous solar current input of 30 amps. The GP-PWM-30 uses pulse width modulation (PWM) technology and a unique four stage charging system with optional equalize setting, to charge and protect your battery bank. The GP-PWM-30 features a LCD digital display that shows solar array charge current, system battery voltage and battery capacity.

Maximum Power Boost Technology. Our New Go Power! 30 Amp Digital Solar Controller now includes Maximum Power Boost Technology™ (MPBT). This new feature allows you to override the normal charging algorithm of the solar controller to 'boost' the solar charge, which is ideal at the end of the daylight to ensure batteries are topped up for the evening. Performance of the solar controller will not be affected if MPBT function is not utilized.
