High-Speed MPPT: Always on Target
Not all Maximum Power Point Tracking controllers were created equal. Most use a “sweep and sleep” method that scans every 30-60 seconds. That’s okay for a clear day, but traditional controllers are constantly off target when used on vehicles or in changing cloud conditions – exactly when power is scarce and is needed the most. 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.
Wide Power Band
Efficiency matters. Many controllers are designed simply to not burn up at high power levels, sacrificing efficiency in low light. At Genasun, we understand that a watt-hour collected during bad weather is worth even more than a watt-hour collected on a sunny day. We tuned our power conversion circuitry to maintain high efficiency over the full range of power levels. Whereas other controllers may charge with efficiencies as low as 80% or worse in low light, the GVB-8 maintains greater than 95% efficiency while operating at only 10% of its rated input (94% for 12V models). When other controllers have given up and are draining your battery, the GVB-8 will still be charging.
LED Indicator
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.
Partial Shade Punch
Genasun controllers shine in partial shade. The 50% power increase from Genasun’s advanced MPPT is often enough to prevent system downtime from partial shade. From antennas and sailboat rigging, to street signs and tree branches, to coffee cups and stickers placed on panels by pedestrians, Genasun MPPT keeps partially shaded solar panels generating more power than any other controller.
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 no moving parts to wear out, Genasun controllers outlast the competition.
