Voltage Boost Solar Charge Controllers

We stock the industry's most efficient boost controllers.  Genasun controllers boost lower-voltage solar panels up to charge higher-voltage lead-acid batteries up to 48V nominal.

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.

Made in the USA, these controllers have:

  • High speed MPPT - adapting to changing light conditions 15 times every second;
  • Computer-controlled, temperature-compensated 3-stage battery charging;
  • Mission-Critical Reliability - each controller is put through complete electrical testing to ensure reliability
