    Does anybody else have this same kit with the same charge controller in the photo?

    Has anybody figured out the functions of the controller? The instructions provided are incomplete.

    It hasn't seemed to be charging recently or not fully.

    There are several functions that can be programmed into the controller but it is a mystery as to what is what.

    Has anybody figured it out on how these will keep a maximum charge?

    Can the charger tell if a panel has a short?

    Thanks. The manual I had did not include page 10.

    I have the 3-panel 45-watt version. It managed to deliver about 3 amps on a sunny summer day in Texas. Mine had a fancier controller with USB and lighter outlets, and a voltmeter. The plastic frame that holds the panels together is flimsy, and the hardware is cheap.

    Cut ONLY the red wire.

    Definitely not the red wire! It is the blue wire!

    Harbor Freight solar panels and controllers are garbage! For the same money, quality components are readily available.

    Too late for those who already own this stuff, but a warning to anyone considering a purchase.

    That pretty well describes most of their electrical stuff in my opinion.

    Except their #36411 crimpers, which will work on power pole connectors.
