The unit does not ship with solar panels, but it does have an integrated 15 Amp PWM Charge controller for external solar panels. So you do not need to buy a charge controller but you will have to buy solar panels separately if you intend to charge the unit with solar.

2 thoughts on “Power Source PSI 300 Portable Solar Generator”

  1. Dear Mr Bennet, I looked at the review of the PSI-300 Solar Generator and noticed a mistake. I am the sole distributor for these in the USA and I like your article more than our own. The statement near the end

    You will need to buy external solar panels to power the battery/batteries. The PSI 300 Power Source solar generator can be powered by solar panels with maximum output of 180W. IN ADDITION A CHARGE CONTROLLER is NECESSARY to make sure the battery in the unit does not get overcharged or completely discharged.

    This unit has a built in 15 Amp Charge Controller so no controller is needed. Also the weight does not include the battery. The battery is an additional 22 lbs.

    I am greatfull for your review.
    Sincerely,
