  • Portable Solar Panel Upgrade Kit - up to 140 watts

    So you've bought a solar panel but you're not happy with the performance or quality of the system components. This is usually due to one or more of the following issues:

    • The regulator is mounted to the back of the solar panel conducting high heat,
    • low quality PWM solar regulator is used,
    • light gauge wiring which causes a large voltage drop to the battery,
    • poor quality connections used throughout the system.

    True sometimes the cause of low performance may also be a low grade solar cell was used in the construction of the system. This is common in cheap solar panels but may not be evident in the short term as the solar cells age. This factor can not be fixed once the purchase as been made unless the low performance is proved and a warranty claim is made against the retailer.

    If you have a reasonably build portable solar panel kit which has issues as listed above we can help gain better performance from your system.

    This Kit can also be used to convert a standard solar panel into a portable solar charge kit.

    What's in the kit:

    • 1x Genasun GV-10 (20-140W) 10A MPPT Solar Charge Controller GV-10-Pb-12V - fitted with a yellow and grey anderson plug and lead.
    • 1x MC-4 to Anderson (Yellow) plug lead 5m.
    • 1x Anderson (grey) to Anderson (grey) lead 2.5m.
    • 1x Battery Clamp to Anderson Plug (grey) lead.
    • 2x pairs of MC-4 plug sets.

    All leads are manufactured from quality 4mm2 solar twin core solar cable which is UV resistant, double insulated and tinned to resist corrosion in harsh environments.

    Overview of the included regulator

    Genasun 10.5A MPPT Solar Charge Controller GV-10-Pb-12V

    A perfect match for your 140W panel. The ultra high-speed MPPT in the GV-10 is so effective it reduces your system cost per Watt.

    • 10.5A 12V 140W
    • 98.3% Peak Efficiency
    • High-Speed MPPT
    • Advanced electronic protections
    • Tiny night consumption (0.9mA)
    • Marine-Grade5-Year Warranty

    A Perfect Match for your 140W Panel
    The GV-10 was designed to maximize the usable energy from a 140W panel. With Continuous Maximum Power Point Tracking, and night consumption of only 0.9mA, the GV-10 delivers results. In fact, the GV-10 is so effective at increasing panel output, it lowers your system cost ($/W) compared to a PWM controller and larger panel.

    Mission-Critical Reliability
    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.

    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. Genasun controllers adapt 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.

    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.

    System Features

    Surviving the Storm with Low Power Burn
    Every controller uses power, but while a typical MPPT controller burns 27mA, the Genasun GV-10 burns a scant 0.9mA. This difference in consumption effectively allows the GV-10 to put an extra half an amp-hour into your battery every day, resulting in a critical benefit while waiting out a snow-covered panel or a few bad weeks of clouds.

    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.

    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.

    The Perfect Match: The GV-10 and a 140W Solar Panel
    Genasun’s GV-10 Continuous MPPT controller is so effective at increasing power output that it actually reduces the system’s cost per Watt ($/W) when paired with a panel such as the Kyocera KD140SX or KD140GX, for example. To compare a Genasun MPPT controller to a PWM controller, you can imagine increasing the size of the panel to make up for the power wasted by a PWM controller. With this approach, the dollar value is calculated by multiplying the power gained by Genasun’s MPPT controllers by the cost per Watt of the solar panel.

    The MPPT Benefit
    10% additional power in the summer. (Hot panels have a Vmp closer to battery Voltage).
    30% additional power in the winter (Cold panels have a higher Vmp).
    50% in partial shading (Partial shade causes a dramatic increase in Vmp. We have consistently seen 50-60% increase in energy harvest from partially shaded panels).

    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.

    Warranty & Support

    The GV-10 solar charge controllers carry a 5-year warranty on materials and workmanship. Genasun’s warranty does not cover damage due to abuse or operation beyond the rated specifications.
