    I have an Alden 80w panel going through an Alden SPS 130 into two 110 batteries. I want to add an 80w folding panel and connect this directly to leisure batteries as and when I need it.
    The suppliers are talking about PWM panels and MPPT compatibility ?
    Basically the 80w panels have a PWM fitted and I need to know if this will work with my existing system.

    Thank you
