    Something els to look at. With 8 panels in parallel, there should be 8 fuse at the combiner box. Have you checked these???

    I would then, also check the short circuit current of each panel. To do this, you will need that current meter BB linked to.

    Trying to push 40 Amps through 160 feet of 8 gauge is a lot like filling a swimming pool with a garden hose.
    Either RE- wire the panels in series strings, AND/Or upgrade the cable.
    If you HAVE to run the panels all in parallel, you will need at least 2 gauge wire.
    ( I use 2 gauge welding lead for my 8 x 220 watt array, 65 foot distance x 2 conductors = 130 feet of 2 gauge.. mine run at 104 volts Open, 80 volts loaded. )
