One of my combiner boxes keeps throwing the breaker. It's happened multiple times now.

Brand new install - I have 3S4P config on Canadian Solar 420 watt panels. I see the current touching 80amps from time to time. The breaker says
In-80A, I'm assuming that's the trip value. Solar Assistant shows 80A peaks, but not at the time it tripped. Im sure there's a delay in the reporting of values. It's too bad there not a table of max/min values for each stat.

Options:
I could move one of the parallel strings to my second combiner box to reduce the input current. The other box has the same number of panels but only shows 2/3 the current as the overloaded box for some reason - that's a topic for another thread.
Any other ideas?
