Genasun Waterproof Boost MPPT – GVB-8 Lithium 28.4V
Genasun BOOST solves the serial connection problem
You might already be aware that if you connect your solar panels in series you increase the probability of a reduced lifespan on the solar panels. Besides that for a serial connection a by-pass diode is required which will decrease the output. Furthermore during partial shadowing which is common among our customers a serial connection will underperform in comparison with the parallel setup. The MoonRay controller solves this and more for a 12V system but for 24V, 48V and 52V battery systems you should choose the Genasun Boost controller for the best performance and health of your solar panels.
Tested and approved for all environments
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, but traditional controllers are constantly off target during changing cloud conditions – exactly when power is scarce and is needed the most. Genasun controllers adapt to changing light conditions 20 times every second. They are always on target, capturing every bit of available sunshine. Simply put, other controllers can’t keep up.
Computer-controlled, temperature-compensated 3-stage battery charging
Precise computer controlled charging ensures the optimal charge cycle for your battery. This increases the battery life, and maximizes battery capacity.
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.
