Genasun GV-Boost 105-350W Boost Charge Controller with MPPT

You have a limited amount of space for example a golf cart the advanced electronics in the GVB controller extract more usable power from your panel than any other controller.

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. These solar charge controllers will take almost any solar panel and boost the voltage to charge a 36V or 48V battery pack.

Because these controllers feature true MPPT, no configuration is necessary; the controller will automatically adapt to your panel.

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, not to mention simpler wiring and installation.

Unmatched Reliability

Genasun controllers are deployed to the most remote locations on earth. They continue delivering power after years at sea, through harsh Antarctic winters, in the upper atmosphere on solar powered airplanes, and in a few off-the-map locations.

Each controller we ship has passed a thorough electrical test 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.  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.

Computer Controlled, Temperature-Compensated 3-Stage Battery Charging

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

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.
