Genasun GV-10 140W-10A : MPPT Solar Controller for 12V Lithium batteries LFP

Designed for Lithium Ion batteries

The MPPT 140W-10A 12V Genasun Lithium battery solar controllers are designed to charge the Lithium Iron Phosphate (LiFe) batteries very efficiently.
The Genasun GV-10 has been tested and approved with Lithium Ion PowerBrick® batteries. This made it possible to perfectly validate all voltage thresholds specific to the Lithium Ion load. This has also enabled us to validate the perfect interoperability with on-board BMS. If you are looking for an MPPT controller for your PowerBrick®, PowerModule… The MPPT 140W-10A solar controller 12V Lithium battery MPPT GV-10 is the right product for you.


They endure marine climates, the harsh Antarctic winters. But also the quasi-vacuum conditions in the upper atmosphere on board solar airplanes, etc.. Genasun controllers are deployed in the world’s most remote locations. Manufactured in the United States, each controller is subjected to extensive electrical testing to ensure reliability.

High-speed MPPT 140W-10A 12V Lithium solar controllers: Always on target

Not all MPPT controllers are equal. Most use a tracking method that scans the entire voltage range every 30-60 seconds. This works for a clear day, but traditional controllers are constantly off-target when weather conditions are less favourable. The Genasun 10A MPPT solar charge controller adapts 15 times per second to the sunshine conditions. They are always on the target and capture every available ray of sunshine.

10 year warranty

The GV-10 sets a new standard for reliability. GENASUN controllers only use ceramic capacitors that can withstand high temperatures continuously and for many years to come. Traditional solar controllers use electrochemical capacitors that degrade over time.

Surviving the Storm with Low Power Burn
Every controller uses power. While a typical PWM controller burns 9mA, the Genasun GV-10 burns a scant 0.9mA. That slow burn is perfect for waiting out a snow-covered panel, or a few bad weeks of clouds.

Partial Shade – In-City Applications.
Genasun controllers shine in partial shade. The 50% power increase from Genasun’s advanced MPPT is often enough to prevent system downtime from partial shade. From street signs and tree branches, to coffee cups and stickers placed on panels by pedestrians, Genasun MPPT keeps partially shaded solar panels generating more power than any other controller.

Complete Power Management
The GV-10 does it all. Plug in the solar panel, connect the battery, and connect the load. The GV-10 will automatically maximize the solar power collected. The advanced battery charging algorithm will maximize the lifetime and capacity of your battery system. The load output will provide smooth, filtered power without the AC chatter found in lesser controllers. This little black box does it all, efficiently and consistently.

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.

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. During third-party testing for FCC compliance, the test engineer asked us, “Is it on?”. Mission accomplished.

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.

Plug and Play, with Advanced Error Protections
We all make mistakes. People plug panels in backwards. 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.
