GP-PWM-25 Amp Digital Solar Regulator
Most solar charging kits need a solar regulator to prevent over-charging. The NEW Go Power! GP-PWM-25 is
a 25 Amp Pulse Width Modulated digital solar regulator. The GP-PWM-25 regulates the current-ow from the
solar module(s) to the batteries, keeping them balanced and at peak performance. The digital display shows the
battery voltage, charging current and battery state of charge. Expandable capability can handle 4-5 solar panels
with a capacity up to 395 watts or 25 amps. The GP-PWM-25 was designed with RVers and mariners in mind, and
is full of great features:
• Pulse Width Modulated charging – Produces more charging power out of solar modules
• Automatically adjusts for 12 or 24 Volt solar systems
• 3 battery charging proles for Gel, AGM and Flooded batteries
• Protects batteries from over temperature, over voltage protection
• Reverse polarity protected - eliminates user errors
• Improved 4 stage charging - Bulk, Float, Absorption and Equalize
• Max wire size up to #6 AWG
• Faster to install, more accurate and user friendly
• Push button operation
• Five year warranty
GP PWM-25 - Handles up to 395 watts of solar
(at a typical Vp of 17.3 V)
