Description
The GVB-8-Pb-WP is a Waterproof Solar Boost MPPT Charge Controller for solar modules in the 105-350W range. Available in several models to support nominal battery voltages of 12V, 24V, 36V, or 48V. This is the Waterproof edition.
The Genasun GVB-8-Pb-WP Runs circles around the Competition
You have a limited amount of space. Advanced electronics in the GVB controller extract more usable power from your panel than any other controller. These solar charge controllers are fully waterproof, which makes them ideal for small vehicles and other applications where the controller will be exposed to moisture.
GVB-8-WP Features…
- LED Display
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. - Built-in Fuse
The GVB controller comes with a fuse built into the power line. This will keep your cart operating safely, reduce the chance of an incorrect installation, and allow end-users to make a quick fuse replacement if needed. - Waterproof: Go ahead, hose it off.
The advanced electronics inside your controller are encased in a proprietary potting compound. After extensive testing with a variety of formulations, we developed a perfect potting compound for our GVB controllers. This extra level of protection ensures trouble-free operation in real-world golf-cart and other vehicular applications.
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 golf cart 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. 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, 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.

*Panel ratings have increased since we designed the GVB. Although we don’t believe in changing specifications without a corresponding engineering change, based on both our customers’ experiences over the years as well as the headroom we designed into the GVB, we feel comfortable recommending the GVB for panels with Imp up to 9A.
**Panel Isc. Maximum input power and maximum input voltage requirements must also be respected.
***Maximum current that the controller could draw from an unlimited source. This specification is not intended for determining PV input.
