Product Description
GENASUN GVB-8-PB-12V 8A 12V MPPT CHARGE CONTROLLER
FOR 12V LEAD ACID BATTERIES
The industry's most efficient boost controllers, these controllers boost lower-voltage solar panels up to charge higher-voltage lead-acid batteries.
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.
- Marine-grade/waterproof
- LED indicator tells you battery state of charge
- No fans, no relays - longer lasting
- 99% Peak Efficiency
- Continuous MPPT
- Advanced electronic protections
- Made in USA
- 5-Year Warranty
Boosting Panel Voltage Saves Money
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. 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.
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 requires 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.
