![]() Whereas other controllers may charge with efficiencies as low as 80% or worse in low light, the GVB-8 maintains greater than 95% efficiency while operating at only 10% of its rated input (94% for 12V models). We tuned our power conversion circuitry to maintain high efficiency over the full range of power levels. At Genasun, we understand that a watt-hour collected during bad weather is worth even more than a watt-hour collected on a sunny day. Many controllers are designed simply to not burn up at high power levels, sacrificing efficiency in low light. Simply put, other controllers can’t keep up. They are always on target, capturing every bit of available sunshine. Genasun controllers adapt to changing light conditions 15 times every second. That’s okay for a clear day, but traditional controllers are constantly off target when used on vehicles or in changing cloud conditions – exactly when power is scarce and is needed the most. Most use a “sweep and sleep” method that scans every 30-60 seconds. Not all Maximum Power Point Tracking controllers were created equal. Because these applications may have the controller more exposed to the elements, we recommend our waterproof version, the GVB-8-WP. With a panel on the roof, your first 10 miles per day could be free. The GVB series of controllers is great for use on golf carts and other small EVs up to 48V. Further options and bulk discounts are available by special order. To order a Custom Voltage controller, hit the “Choose Options” button next to the GVB-8-Pb-CV or GVB-8-Li-CV SKU below, and select the custom voltages from the drop-down menu. If these standard configurations don’t work for your application, a custom charge profile can be programmed at the factory to match the specs of your lead-acid or Li battery. Genasun stocks the GVB-8 for lead-acid batteries and for a variety of Lithium chemistries and cell configurations. We’ve worked with every chemistry and have tailored charge profiles to help you get more capacity and cycle life from your battery pack. Our Lithium charging algorithms draw from a decade of experience building lithium battery packs for harsh environments. Tailored Lithium Charging Profiles Available Compared to a higher-voltage panel, these have fewer cells, fewer interconnections to go bad, and larger cell area to defend against partial shading, all resulting in a more robust system. ![]() ![]() In addition, Genasun’s GVB-8 boosts system reliability by allowing the use of lower-voltage solar panels. Made in the USA, each controller is put through complete electrical testing to ensure reliability. 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. Genasun controllers are deployed to the most remote locations on earth. So stop stringing small 12V panels in series to charge at 24V or 48V, and reap the rewards of the GVB-8’s boost technology. Larger panels are cheaper per Watt than smaller panels, so using one large panel and a GVB-8 results in a lower system cost than using smaller panels in series and also allows simpler wiring and installation. Boost Panel Voltage to Save Money and Simplify Installation And our 12V boost controller will charge 12V batteries from specialty low-voltage panels. ![]() A 48V battery from a 12V panel? We’ve got you covered. Want to charge a 24V battery with a 60-cell (18V) solar panel? No problem. Because these controllers feature true MPPT, no configuration is necessary the controller will automatically adapt to your panel. In fact, the GVB’s will work with almost any panel that’s below your battery voltage. These controllers will take a lower-voltage panel and boost the voltage to charge a 24V, 36V or 48V battery pack. The GVB-series controllers, in contrast, pump electricity up hill. Most solar charge controllers move power from a higher-voltage panel to a lower-voltage battery bank. ![]()
