Mission-Critical Reliability
GV-5 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.

Get the Ceramic Edge. Electrolytic-Free with 10 Year Warranty
GV-5 Ceramic controller sets a new benchmark for reliability. Traditional controllers have components filled with fluid electrolytes that boil off over time, causing system failure. GV-5 Solid Ceramic controllers have no fluid. They don’t wear out in the heat. Backed by an industry leading 10 year warranty, these controllers take reliability to a new level.

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-5 controller adapts 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.

Made in the USA




Surviving the Storm with Low Power Burn
Every controller uses power. While a typical PWM controller burns 9mA, the GV-5 burns a scant 0.15mA. That slow burn is perfect for waiting out a snow-covered panel, or a few bad weeks of clouds.

Partial Shade – In-City Applications.
GV-5 controller shine in partial shade. The 50% power increase to prevent system downtime from partial shade. From street signs and tree branches, to coffee cups and stickers placed on panels by pedestrians, GV-5 keeps partially shaded solar panels generating more power than any other controller.

Complete Power Management.
The GV-5 does it all. Plug in the solar panel, connect the battery, and connect the load. The GV-5 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 GV-5 MPPT controller can draw from the same panel. By constantly adapting to changing light conditions, this 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. GV-5 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-5 controller uses advanced electrical design that obsoletes these parts. With fewer moving parts to wear out, GV-5 controller outlasts 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.
