Genasun GV-10 20-140W 10.5A 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.

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.

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. Custom voltages can be programmed at the factory to match the Float Voltage (CV voltage) of your battery. Please select the Custom Voltage option from the drop down, and email support@genasun.com to specify the voltage.

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.

Radio Silence.
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.

Fault Tolerance.

The Perfect Match: The GV-10 and a 140W Solar Panel
Genasun’s GV-10 Continuous MPPT controller is so effective at increasing power output that it actually reduces the system’s cost per Watt ($/W) when paired with a panel such as the Kyocera KD140SX or KD140GX, for example. To compare a Genasun MPPT controller to a PWM controller, you can imagine increasing the size of the panel to make up for the power wasted by a PWM controller. With this approach, the dollar value is calculated by multiplying the power gained by Genasun’s MPPT controllers by the cost per Watt of the solar panel.

The MPPT benefit is:
10% additional power in the summer. (Hot panels have a Vmp closer to battery Voltage.)
30% additional power in the winter (Cold panels have a higher Vmp.)
50% in partial shading (Partial shade causes a dramatic increase in Vmp. We have consistently seen 50-60% increase in energy harvest from partially shaded panels.)

MPPT Controller Value, with a 140W panel:

Summer: extra 14 watts
Winter: extra 42 watts
Partial Shade: extra 70 watts

Steady Power Source.
Life is unpredictable. PWM controllers amplify that unpredictability. A small amount of shade can drop PWM power output to 2/3's of what a Genasun MPPT controller can draw from the same panel. By constantly adapting to changing light conditions, Genasun’s advanced MPPT controllers provide a steadier source of power, keeping your system running in uncertain weather.
