Maximize Solar Efficiency with the Genasun GV-10 Lead-Acid MPPT Solar Charge Controller

Optimized for 140W Panels and More

The Genasun GV-10 is engineered to extract the maximum usable energy from your 140W solar panel and can take up to approximately 200W solar panels if within the current and voltage limits. Featuring Continuous Maximum Power Point Tracking and minimal night consumption of only 0.9mA, this controller not only boosts panel output but also reduces overall system costs in terms of $/W compared to PWM controllers with larger panels.

Unmatched Reliability for Critical Missions

Trusted in the most remote and demanding environments on earth – from harsh Antarctic winters to high-altitude solar-powered aircraft – the USA-made Genasun GV-10 undergoes comprehensive electrical testing to ensure unmatched reliability. If your power needs are mission-critical, this is the controller you need.

High-Speed MPPT for Consistent Energy Capture

Unlike traditional controllers that sweep the voltage range every 30-60 seconds, the Genasun GV-10 adapts to changing light conditions 20 times per second. This high-speed MPPT ensures optimal performance even during fluctuating cloud coverage, capturing every bit of available sunlight.

Advanced Lithium Charging for Extended Battery Life

Benefit from Genasun's nine years of experience in Lithium battery technology. Our advanced charging algorithms are designed for various Lithium chemistries, enhancing battery capacity and cycle life. The GV-10 is available in multiple charge profiles for common Lithium configurations.

Key Features:

  • 98.3% Peak Efficiency and High-Speed MPPT
  • Advanced electronic protections
  • Ultra-low night consumption (0.9mA)
  • Marine-Grade build quality
  • Comprehensive 5-Year Warranty
  • Made in the USA

Innovative Design for Durability and Silence

The GV-10's innovative design features no fans or relays, eliminating common failure points found in other controllers. This advanced electrical design ensures lasting performance with fewer moving parts. Additionally, Genasun controllers are designed to eliminate RF emissions, preventing interference with nearby electronics. 

During third-party testing for FCC compliance for one of our controllers, the test engineer asked us, “Is it on?”. Mission accomplished.

Built-In Fault Tolerance for Peace of Mind

Safety features include reverse polarity protection on both battery and panel, and an internal user-replaceable fuse, ensuring your system is safeguarded against common electrical faults.

Embrace the Genasun GV-10 for a solar charge controller that combines efficiency, reliability, and advanced technology, perfect for keeping your Lithium batteries charged and ready.

1: Panel Isc. Max input power and max input voltage requirements must also be respected.
2: Max current that the controller could draw from an unlimited source. This specification is not intended for determining PV input.
3: Max ambient temperature for full operating power.
4: If the battery voltage drops below this point, the controller will attempt to run an absorption cycle. Otherwise, it will charge to the float voltage.
