Reliable Restart Prevents Deadlock
When a lithium battery is over-discharged, its BMS typically will disconnect the output until a charge source is present. Many unsophisticated solar charge controllers will wait for a battery to be present to begin charging, resulting in a system that never recovers. Not so with the GVB! Our GVB controller will attempt to begin charging even if no battery is present, and is able to restart most lithium batteries, so your system will automatically recover without manual intervention or a service call.
Running circles around the Competition
You have a limited amount of space on the roof of your golf cart. Advanced electronics in the GVB controller extract more usable power from your panel than any other controller. These solar charge controllers are fully waterproof, which makes them ideal for golf carts and other applications where the controller will be exposed to moisture.
Boosting Panel Voltage Saves Money
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 golf cart solar charge controllers will take almost any solar panel and boost the voltage to charge a 48V LiFePO4 battery pack. Because these controllers feature true MPPT, no configuration is necessary; the controller will automatically adapt to your panel. 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, not to mention simpler wiring and installation.
Genasun controllers are deployed to the most remote locations on earth. They continue delivering power after years at sea, through harsh Antarctic winters, in the upper atmosphere on solar powered airplanes, and in a few off-the-map locations. Each controller we ship has passed a thorough electrical test 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 requires 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.
Computer controlled, CC/CV battery charging
Precise computer controlled charging ensures the optimal charge cycle for your battery. GVB controllers for lithium employ industry-standard Constant-Current Constant-Voltage (CC/CV) charging for widest lithium battery compatibility. The GVB's float or CV voltage is equivalent to 3.55V per cell, which is suitable for most LiFePO4 battery packs (check with your battery manufacturer to be sure).
