Go Power

<p>Since 1996, Go Power has established itself as a leader in mobile solar power and the top choice for off-grid power in RV, marine, and fleet applications. Founded in Victoria, British Columbia, Canada, as a small distributor of solar energy products, the company is now part of the Dometic Group, bringing decades of expertise in portable renewable energy solutions to outdoor enthusiasts and commercial operators across North America.</p><h3>Pioneering Off-Grid Power Solutions</h3><p>From humble beginnings as a Canadian distributor, Go Power has grown to become one of North America's leading suppliers of recreational and business solar solutions. The brand's comprehensive product lineup addresses every aspect of mobile power generation and management, from capturing solar energy to storing it efficiently and converting it for practical use. Whether you're an RV owner seeking extended boondocking capability, a boater planning long cruises away from shore power, or a fleet manager looking to reduce fuel costs, Go Power provides integrated systems designed for reliable performance in demanding off-grid environments.</p><h3>Complete Mobile Power Systems</h3><p>Go Power provides a full range of high-quality solar chargers, inverters, controllers, and power accessories—dependable and cost-effective mobile power solutions when grid power is unavailable or unsustainable. The brand's <a href="/11123-go-power-inverters-200588">inverters</a> serve as the critical link between DC battery power and AC household appliances, converting stored solar energy into usable electricity for microwaves, televisions, computers, and other essential devices. While older inverters use modified sine wave technology, Go Power's pure sine inverters provide superior performance and assurance that all current and future devices will run optimally.</p><p>Go Power's solar panels, inverters, controllers, and batteries provide a durable, dependable, and cost-effective solution wherever mobile power is needed. Their <a href="/11123-go-powercarmanah-vehicle-battery-2476">vehicle batteries</a>, available in both AGM and lithium technologies, form the backbone of any mobile power system, storing solar-generated energy for use during nighttime hours or cloudy conditions. The company's product design philosophy emphasizes easy installation, durability in harsh conditions, and seamless integration between components.</p><h3>Industry Recognition and Quality Standards</h3><p>Go Power is the choice of RVers everywhere and is available pre-installed on many types of RVs, including Jayco, Forest River, and Tiffin. The company backs its rigid solar panels with an industry-leading 25-year power-output warranty, demonstrating confidence in long-term performance and reliability. This commitment to quality has earned the brand multiple industry accolades and a loyal following among off-grid adventurers who depend on consistent power in remote locations.</p><h3>Environmental and Economic Benefits</h3><p>Go Power's solar solutions are environmentally friendly—no more running generators or idling work trucks to keep batteries charged, and unlike generators, solar solutions don't require fuel or give off pollutants. The silent operation of solar power systems preserves the tranquility of natural settings while eliminating recurring fuel expenses. Mobile solar installations also extend battery lifespan through optimal charging management, prevent dead battery situations in remote locations, and require minimal maintenance beyond keeping panels clean and checking connections.</p>

Product Details

The Go Power 83839 is a 40 amp MPPT (Maximum Power Point Tracking) solar charge controller designed for 12-volt battery systems with dual-bank charging capability. This advanced controller is an essential component of any RV or marine solar charging system, protecting battery life by preventing overcharging while maximizing solar panel efficiency.

Key Features:

  • 40 amp maximum charge current with MPPT technology for superior charging efficiency
  • Dual-bank capability allows independent charging of two separate battery banks
  • 12-volt system voltage with automatic battery type recognition
  • Compatible with multiple battery types including AGM, Gel, Flooded Lead Acid, and Lithium (LiFePO4)
  • MPPT charging technology extracts maximum power from solar panels, charging batteries faster than traditional PWM controllers
  • Multi-stage charging algorithm extends battery life and maintains optimal battery health
  • Stackable design allows connection of multiple controllers for expanded solar capacity
  • Prevents harmful overcharging with automatic voltage regulation

MPPT technology optimizes solar panel output across all sun conditions and panel orientations, making this controller ideal for serious solar installations on RVs, boats, and off-grid applications. The dual-bank feature is particularly valuable for systems requiring separate house and starter battery charging.
