Voltage-Boost: A True Problem-Solver

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 lower-voltage 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. Because these controllers feature true MPPT, no configuration is necessary; the controller will automatically adapt to your panel. Want to charge a 24V battery with a 60-cell (18V) solar panel? No problem. A 48V battery from a 12V panel? We’ve got you covered. And our 12V boost controller will charge 12V batteries from specialty low-voltage panels.

Boost Panel Voltage to Save Money and Simplify Installation

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.  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.  

Boost System Reliability with the GVB-8

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. In addition, Genasun’s GVB-8 boosts system reliability by allowing the use of lower-voltage solar panels.  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.

Tailored Lithium Charging Profiles Available

Our Lithium charging algorithms draw from a decade of experience building lithium battery packs for harsh environments. We’ve worked with every chemistry and have tailored charge profiles to help you get more capacity and cycle life from your battery pack.

Custom Voltages Available

Genasun stocks the GVB-8 for lead-acid batteries and for a variety of Lithium chemistries and cell configurations. 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. 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. Further options and bulk discounts are available by special order.

Waterproof Versions Available

The GVB series of controllers is great for use on golf carts and other small EVs up to 48V.  With a panel on the roof, your first 10 miles per day could be free.  Because these applications may have the controller more exposed to the elements, we recommend our waterproof version, the GVB-8-WP .
