MPPT Charge Controller
4A, 12V
GV-4-Pb-12V

4A 12V MPPT controller. Small, critically efficient, and cost-effective, the GV-4 gets more from every panel.

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.

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.

Surviving the Storm with Low Power Burn
Every controller uses power. While a typical PWM controller burns 9mA, the Genasun GV-4 burns a scant 0.125mA. 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.

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.

Fault Tolerance
Electronic reverse-battery protection. Electronic reverse-panel protection.
