  • Portable Solar Panel Upgrade Kit - up to 260 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 EP Solar 20A 12/24V (260/520W) Solar Charge Controller 2210A - fitted with a yellow, blue 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.
