GVB Boost Solar Charge Controllers

For applications where a solar panel voltage needs to be boosted to a higher battery voltage, we are proud to introduce the GV-Boost series of boost solar charge controllers with maximum power point tracking.

These new controllers will enable system configurations not otherwise possible. With the GVB24-8, for instance, customers have been able to use a 12V nominal solar panel with a 24V battery system. This new line of solar charge controllers have all of the industry-leading features of Genasun's GV-6 and GV-9 MPPT Solar Charge Controllers.

These controllers connect between your solar panel and batteries like any charge controller, but sophisticated electronics allow the controller to operate the solar panel at its most efficient voltage, resulting in significant gains in power. To learn how Maximum Power Point Tracking works and for a more detailed description of our products, have a look at About Maximum Power Point Tracking.
