Genasun GV-Boost for Lithium Batteries. The industry's most efficient MPPT boost controller. Want to see a small solar panel charge a 24V, 36V, or even a 48V Lithium battery pack? Get a GV-Boost for Lithium Batteries! 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 uphill, taking the output from a lower voltage panel and boosting it to recharge as high as a 48V battery bank! The GVB is so efficient at doing this that you can connect almost any panel that is below your battery voltage and it works without a fuss. The world of options just opened up for you to tailor your system to meet any need. Want to use a small panel because of space limitations? No problem! Want to use a single panel to minimize costs? Done! Want to run your DC system at 24V, 36V, or 48V but are worried about supporting panel configurations? Problem solved! The GVB is designed to support panels, from the small guys all the way up to 350 watts providing a very large array of options. Knowing that you also expect the best in efficiency, reliability and toughness found in their other charge controllers, Genasun engineered the GVB to the same standard of excellence. The GV-Boost operates at an amazing 99% peak efficiency while also employing Continuous Maximum Power Point Tracking that monitors the solar panel at 15 times per second (1,200 times faster than the standard MPPT controller), ensuring that every available bit of power is captured and transferred into your batteries. In fact, it is so effective at increasing panel output that it will maximize battery charging opportunities, even in stormy or low light conditions, when the competitors fall short. A very important feature when bad weather hits but you still need electricity. Like all Genasun products, it is meticulously designed to work in the most extreme environments, able to endure years at sea, harsh Antarctic winters, extended operations in the upper atmosphere, and those off-the-map locations nobody has ever heard about. This ruggedness gives you the peace of mind that whatever you can throw at the GVB, it will provide you worry free operations, with no maintenance, for the long haul. Mission-critical reliability. Genasun has spent countless hours working on the little things that make their product the best, even though the average user may not think to look for them. The GVB dramatically reduces, or even eliminates, RF emissions, which are created during the DC/DC conversion process. RF emissions waste energy and interfere with nearby or attached electronics, but with Genasun, that concern is removed. And while fans can get clogged with dust and dirt, and relays can eventually stop switching, Genasun controllers use advanced electrical design so that these parts are obsolete. Genasun also knows that we all make mistakes, plugging in panels backwards, wires touching during installation, or rodents chewing on cables and causing a short. Life just happens. Genasun has you covered with their advanced built-in electronic protection measures that will instantly cut power to a short circuit. The GVB will automatically test for when the short is removed, and once cleared, will switch back to normal operations. Nothing to reset, and no fuses to replace. It just works. The Genasun GV-Boost for Lithium charging algorithms draw from nine years of experience building Lithium battery packs for the harshest environments. The engineers worked with every battery chemistry and have tailored charge profiles to help you get more capacity and cycle life from your battery pack, ensuring maximum life and maximum performance. The GV-Boost for Lithium is stocked in 12V, 24V and 48V nominal charge profiles for LiFePO4 batteries. The standard float voltages correspond to 3.55V per cell for compatibility with most batteries (check with the battery manufacturer to be sure). Custom voltages can be programmed at the factory to match the float Voltage (CV voltage) of your battery chemistry, contact Hybrid Power Supply for ordering information. Efficiency, reliability, toughness, and now flexibility. Let Genasun remove distractions from your holiday, your adventure, and your system. Let your focus be all about taking the journey. Genasun - unmatched performance, efficiency, and reliability. Not just good, but uber-awesome.
