  • Genasun GV-Boost 8A MPPT Solar Boost Charge Controller GVB-8-Pb-12V

    Note - this solar boost charge controller is available in 12V, 24V, 36V or 48V models. The photos attached are for example only and show the 48V model. We stock 12V and 24V model and have the same casing. We also stock a golf cart water proof version at 36V or 48V but if you want this model in 36V or 48V model please contact us.

    Overview

    The industry's most efficient boost controllers. These controllers boost lower-voltage solar panels up to charge higher-voltage lead-acid batteries.

    • 8A 12V 105W
    • 99% Peak Efficiency
    • Continuous MPPT
    • Marine-Grade
    • Advanced electronic protections
    • 5-Year Warranty

    Want to boost a low voltage panel to charge your higher voltage battery? Get a GVB
    Most solar charge controllers move power from a higher voltage panel to a lower voltage battery bank.  The GVB-series controllers, in contrast, pump electricity up hill. These controllers will take a standard 12V panel and boost the voltage to charge a 24V, 36V or 48V battery pack.  In fact, the GVB's will work with almost any panel that's below your battery voltage. This makes finding a good panel easy:  just make sure to stay below 8A panel current and 63 Volts (open circuit). Larger panels are cheaper per Watt than smaller panels, so using one large panel and a boost controller results in a significantly lower system cost than smaller panels in series with a conventional charge controller.

    Mission-Critical Reliability
    Genasun controllers are deployed to the most remote locations on earth. They endure years at sea, harsh Antarctic winters, freezing conditions in the upper atmosphere on solar powered airplanes, and in a few off-the-map locations. Made in the USA, each controller is put through complete electrical testing to ensure reliability. If you need mission-critical power, this is your controller.

    High-Speed MPPT: Always on Target
    Not all Maximum Power Point Tracking controllers were created equally. Most use a sweep and sleep method that scans the entire voltage range every 30-60 seconds. That's okay for a clear day, with a stationary panel. But moving vehicles and changing cloud cover require a faster, more advanced controller. Genasun controllers adapt to changing light conditions 15 times every second. They are always on target, capturing every bit of available sunshine. Simply put, other controllers can't keep up.

    Computer-controlled, 4-Stage battery charging
    Precise computer controlled charging ensures the optimal charge cycle for your battery. This increases the battery life, and maximizes battery capacity.

    Features

    LED Indicator
    The built-in LED will quickly tell you that you've installed the controller correctly. Simple to read, it will also let you know when the battery is charging from solar power, and when the battery has reached full charge.

    Marine Grade: Reliable Power After Years at Sea
    Genasun Boost controllers provide reliable power in the harshest environments on earth. GVB's have been powering boats on round-the-world sailing races for years.

    No Fans. No Relays.
    Fans get clogged with dust and dirt. Relays eventually stop switching. Genasun controllers use advanced electrical design that obsoletes these parts. With fewer moving parts to wear out, Genasun controllers outlast the competition.
