Get the Ceramic Edge: Electrolytic-Free with 10-Year Warranty
Genasun’s GV-5 ceramic controllers set a new benchmark for reliability. Other controllers use electrolytic capacitors filled with fluid that boils off over time, causing degradation in performance and eventual failure. The GV-5 is entirely solid-state, built with only ceramic capacitors. Genasun ceramic controllers have no fluid. They don’t wear out in the heat, and performance doesn’t degrade in the cold. Backed by an industry-leading 10-year warranty, these controllers take reliability to a new level.
Widest Power Band
Efficiency matters. Many controllers are designed simply to not burn up at high power levels, with no attention to 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 GV-5 maintains greater than 95% efficiency down to a few watts. At even lower levels, the GV-5 engages a special mode that boosts electrical efficiency to an astounding peak of 99.8%, consuming less than 0.2 milliamps and charging down to mere milliwatts of solar input. When other controllers have given up and are draining your battery, the GV-5 will still be charging.
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.
Tailored Lithium Charging Profiles Available
Our Lithium charging algorithms draw from a decade of experience building lithium battery packs for harsh environments. We’ve worked with every chemistry and have tailored charge profiles to help you get more capacity and cycle life from your battery pack.
Custom Voltages Available
Genasun stocks the GV-5 for lead-acid batteries and for a variety of lithium chemistries and cell configurations. If these standard configurations don’t work for your application, a custom charge profile can be programmed at the factory to match the specs of your lead-acid or Li battery. To order a Custom Voltage controller, hit the “Choose Options” button next to the GV-5-Pb-CV or GV-5-Li-CV SKU below, and select the custom voltages from the drop-down menu. Further options and bulk discounts are available by special order.
