Genasun GV-4 10-50W 4A Solar Charge Controller with MPPT

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 needs the most. The Genasun GV-4 MPPT solar charge controller adapts 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.

Mission-Critical Reliability
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.

Computer controlled, 4-Stage battery charging
Precise computer controlled charging ensures the optimal charge cycle for your battery. This increases the battery life, and maximizes battery capacity.

Plug and Play, with Advanced Error Protections
We all make mistakes. People plug panels in backwards. Wires get touched. Rodents chew through cables and cause short circuits. Stuff happens. But don't worry, we've got you covered. Advanced built-in electronic protections will instantly cut power to a short circuit. The controller will automatically test to see when the short is removed. Once it's clear, normal operation will resume. There's nothing to reset. No fuses to replace. The GV-4 just works.

    Can the unit be used on other batteries besides lead acid Answer:
    Hi Pieter, no this is the lead acid version. There are other versions for Li-ion on this site. Regards Solar Shop Support

    Do you have a boost controller? Believing that 'watts-r-watts' & the voltage can be manipulated, we want to use a 50w x 12vdc panel then boost the voltage to charge a 24v lithium battery. The 12v panel is about 1/4th the cost of a 24v panel and has 20w more capacity. But then I know enough to be dangerous & this will be for several products so I want it to work.~ Answer:
    Hi Jerry, we do have the correct boost mppt but it costs way more than a 36V panel so it wouldn't make financial sense to do this if we understand you correctly.
