Genasun GV-10 20-140W 10A Solar Charge Controller with MPPT for Lithium Batteries
A Perfect Match for your 140W Panel
The GV-10 was designed to maximize the usable energy from a 140W panel. With Continuous Maximum Power Point Tracking, and night consumption of only 0.9mA, the GV-10 delivers results. In fact, the GV-10 is so effective at increasing panel output, it lowers your system cost ($/W) compared to a PWM controller and larger panel.
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 needs 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. Advanced Lithium Charging Algorithms Our Lithium charging algorithms draw from nine years 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-10 in a variety of charge profiles for the most common Lithium chemistries and cell configurations.

Surviving the Storm with Low Power Burn
Every controller uses power, but while a typical MPPT controller burns 27mA, the Genasun GV-10 burns a scant 0.9mA. This difference in consumption effectively allows the GV-10 to put an extra half an amp-hour into your battery every day, resulting in a critical benefit while waiting out a snow-covered panel or a few bad weeks of clouds.
Most MPPT solar charge controllers broadcast Radio Frequency noise from the DC/DC conversion circuit. Unfiltered inputs and outputs waste energy and interfere with nearby or attached electronics. Genasun worked to eliminated RF emissions from our line of charge controllers.
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.
Reverse polarity protection on battery and panel
Internal user-replaceable fuse
The GV-10 solar charge controllers carry a 5-year warranty on materials and workmanship. Genasuns warranty does not cover damage due to abuse or operation beyond the rated specifications.
