Genasun GV-Boost 105-350W MPPT Solar Boost Charge Controller for Lithium Batteries
Want to see a 27V grid-tie panel charge a 48V battery pack?
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. This controller will take a lower voltage panel and boost the voltage to charge a 24V battery pack.
In fact, the GVB's will work with almost any panel that's below your battery voltage.
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.
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. 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 require 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.
Advanced Lithium Charging Algorithms
Drawing on more than 10 years of advanced lithium battery and controller development, Genasun offers a complete line of lithium solar charge controllers. These units employ industry-standard Constant-Current Constant-Voltage (CC/CV) charging for widest battery compatibility. Custom Voltages Available
Genasun GV-Boost come in 12V, 24V and 48V nominal charge profile for LiFePO4 batteries. The standard float voltages correspond to 3.55V per cell for compatibility with most batteries (check with your battery manufacturer to be sure).
Custom voltages can be programmed at the factory to match the float Voltage (CV voltage) of your battery chemistry.

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.
Marine Grade: Reliable Power After Years at Sea
Genasun Boost controllers provide reliable power in the harshest environments on earth. GVB's have been powering boats on round-the-world sailing races for years.
No Fans. No Relays.
Fans get clogged with dust and dirt. Relays eventually stop switching. Genasun controllers use advanced electrical design that obsoletes these parts. With fewer moving parts to wear out, Genasun controllers outlast the competition.
