Go Power

<h3>Go Power: Three Decades of Off-Grid Power Innovation</h3><p>Few brands can claim to have shaped an entire category the way Go Power has shaped mobile solar power. <strong>Founded in 1996 in Victoria, British Columbia</strong>, Go Power started as a small Canadian distributor of solar energy products and has since grown into one of North America's leading suppliers of recreational and commercial solar solutions. Now operating as part of the Dometic Group, Go Power brings the resources of a global outdoor lifestyle company to bear on a singular mission: keeping adventurers, mariners, and fleet operators powered wherever the grid cannot reach.</p><h3>Built for RV, Marine, Fleet &amp; Overlanding Life</h3><p>Go Power's product philosophy is rooted in versatility and reliability. Whether you're a full-time RVer dry-camping in a remote canyon, a boater planning an extended offshore cruise, or a fleet manager looking to reduce generator fuel costs, Go Power offers a complete ecosystem of mobile power hardware designed to work together seamlessly. Their systems are pre-installed by major RV manufacturers including Jayco, Forest River, and Tiffin — a testament to the brand's reputation for durability and ease of integration.</p><p>The product lineup spans solar panels (rigid, flexible, and portable), AGM and lithium batteries, solar charge controllers, transfer switches, battery chargers, and — at the heart of many complete systems — <a href="/11123-go-power-power-inverter-14297">power inverters</a>. These components are engineered to work as an integrated whole, with Go Power's proprietary PowerTrak&trade; technology optimizing power flow and efficiency across compatible devices in a single, connected system.</p><h3>Pure Sine Wave Power Where It Counts</h3><p>A critical piece of any off-grid setup is the ability to convert DC battery power into clean, usable AC electricity. Go Power's <a href="/11123-go-power-power-inverter-14297">power inverter</a> lineup — including Smart Sine Wave, Advanced Sine Wave, and Inverter Charger models — delivers pure sine wave output that is safe for sensitive electronics like laptops, medical devices, and modern appliances. Many models feature built-in transfer switches, mobile app connectivity, and multistage charging capability, making them well-suited to both entry-level RVers and seasoned off-grid enthusiasts who demand reliable, intelligent power management.</p><h3>Award-Winning Recognition</h3><p>Go Power's commitment to quality has earned consistent industry recognition. The brand has secured gold-level honors in RV Magazine's Readers' Choice Awards and has been celebrated for providing reliable off-grid power that enhances the mobile lifestyle. With products available at over 700 locations across North America and backed by industry-leading warranties, Go Power remains the benchmark for mobile solar solutions.</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.
