Genasun MPPT Boost Solar controller 8A for 48V Lithium Iron Phosphate battery (LiFePO4)

High reliability

The MPPT Boost 8A solar controller for Genasun 48V Lithium battery is deployed in the world’s most remote locations. It can endure marine climates, the harsh Antarctic winters, the quasi-vacuum conditions in the upper atmosphere on board solar airplanes, etc. Manufactured in the United States, each controller is subjected to extensive electrical testing to ensure reliability.

Ultra-fast MPPT Boost: Always on target

Not all MPPT Boost 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 GV-Boost 105-350W 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.

Designed for Lithium-Ion batteries

The Genasun controllers are designed to charge the Lithium Iron Phosphate (LiFePO4) batteries very efficiently.
The Genasun GV-Boost has been tested and approved with Lithium Ion PowerBrick® batteries. Unlike other controllers originally designed for lead-acid 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 Boost controller for your PowerBrick® 48V battery, PowerModule, etc… The MPPT Boost 8A Solar Controller for 48V Lithium GV-Boost battery is the right product for you.

10 years warranty

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

LED Display
The built-in LED will quickly tell you that you’ve installed the controller correctly. Simple to read, it will also let you know when the battery is charging from solar power, and when the battery has reached full charge.

Marine Grade: Reliable Power After Years at Sea
Genasun Boost controllers provide reliable power in the harshest environments on earth. GVB’s have been powering boats on round-the-world sailing races for years.

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.
