Genasun GVB-8 MPPT Voltage Boosting Solar Controller for LiFEPO4 Batteries

The Genasun GV-8 LiFePO4 solar controller is an excellent choice for anyone who is looking for a high-quality, efficient, and reliable solar charge controller for their LiFePO4 battery system. Here are some reasons why:

  • Designed for LiFePO4 Batteries: The GV-8 LiFePO4 controller is specifically designed to work with LiFePO4 batteries, which have different charging requirements than traditional lead-acid batteries. It uses advanced algorithms to optimize the charging process and ensure that your batteries are charged safely and efficiently.

  • High Efficiency: The GV-8 LiFePO4 controller boasts an impressive 99% efficiency rating, which means that it converts nearly all of the power generated by your solar panels into usable energy for your batteries.

  • Lightweight and Compact: At just 4.2 ounces, the GV-8 LiFePO4 controller is one of the smallest and lightest solar charge controllers on the market, making it an ideal choice for installations where space is limited.

  • Advanced MPPT Technology: The GV-8 LiFePO4 controller uses advanced Maximum Power Point Tracking (MPPT) technology to maximize the amount of energy your solar panels produce, ensuring that your batteries are charged as efficiently as possible.

  • Intelligent Battery Management: The GV-8 LiFePO4 controller includes a number of built-in safety features to protect your batteries from overcharging and over-discharging, ensuring that they have a long and reliable lifespan.

  • Easy to Install and Use: The GV-8 LiFePO4 controller is designed for easy installation and setup, with a simple and intuitive user interface that makes it easy to monitor and control your solar power system.

  • Overall, the Genasun GV-8 LiFePO4 solar controller is a top-quality choice for anyone who wants to get the most out of their LiFePO4 battery-powered solar power system. Its specialized design for LiFePO4 batteries, high efficiency, lightweight and compact design, advanced MPPT technology, intelligent battery management, and user-friendly interface make it an excellent investment for anyone who wants to power their life with solar energy.


High-Speed MPPT: Always on Target

Not all Maximum Power Point Tracking controllers were created equal. Most use a “sweep and sleep” method that scans every 30-60 seconds. That’s okay for a clear day, but traditional controllers are constantly off target when used on vehicles or in changing cloud conditions – exactly when power is scarce and is needed the most. Genasun controllers adapt 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.

Wide Power Band

Efficiency matters.  Many controllers are designed simply to not burn up at high power levels, sacrificing efficiency in low light.  At Genasun, we understand that a watt-hour collected during bad weather is worth even more than a watt-hour collected on a sunny day.  We tuned our power conversion circuitry to maintain high efficiency over the full range of power levels.  Whereas other controllers may charge with efficiencies as low as 80% or worse in low light, the GVB-8 maintains greater than 95% efficiency while operating at only 10% of its rated input (94% for 12V models).  When other controllers have given up and are draining your battery, the GVB-8 will still be charging.

LED Indicator

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.

Partial Shade Punch

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 antennas and sailboat rigging, to 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.

Marine Grade: Reliable Power After Years at Sea

With all stainless steel and plated brass hardware, 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 no moving parts to wear out, Genasun controllers outlast the competition.
