140W 10A Solar Charge Controller with MPPT for Lithium Batteries (#1669)

You need these parts to work our PCB
Your Price: $135.00
Lead Time: 2 weeks

Product Options



  • 10.5A MPPT Controller.
  • 98.3% Peak Efficiency
  • High-Speed MPPT
  • Advanced electronic protections
  • Tiny night consumption (0.9mA)
  • Marine-Grade
  • 5-Year Warranty

Note: For GV-10-LI-12.5V and GV-10-LI-16.7V, if you are purchasing this controller to charge batteryspace's lithium battery pack that has a PCB added, you must also added Product ID # 9632 to the controller. Otherwise, if the PCB detect low voltage and shut down, the GV-10 will not starting charging again. For more detail please take a look at Product ID # 9632. For GV-10-LI-14.2V, you do not need #9632.

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.

Mission-Critical Reliability
GV-10 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. GV-10 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
GV-10 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.

Made in the USA



Surviving the Storm with Low Power Burn
Every controller uses power, but while a typical MPPT controller burns 27mA, the 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. GV-10 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. GV-10 controllers use advanced electrical design that obsoletes these parts. With fewer moving parts to wear out, Genasun controllers outlast the competition.

Fault Tolerance.
Reverse polarity protection on battery and panel
Internal user-replaceable fuse

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.)
