Alden SPS 130 advice for adding folding panel (1 Viewer)

[K1m]

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
