    Default Using different solar panels in parallel

    My new carvan has an HCDP power pack. the solar input is 270w max, but i'm told that the max open circuit voltage is 26V.
    The van is to have a 160W panel fitted to the roof which is removable if required, Voc is 21.9V.
    I currently have a pair of 50W panels that fold-up and have used these with my trailer the Voc is 21.0V on the 2x 50w.
    My question is, if needed could I connect all 3 to give me 260W or is this a bad idea.

    Should work, the volts is close enough.

    Simply connect all 3 in parallel (or 2 of the 3) - no problem with that.
