[RE-wrenches] Combiner breakers tripping

[All Solar]

Wrenches,
I've got a c client with an Outback PV combiner with DIN mount CBs. He's
let me know a few times that 9 of 10 , or at least 50%
of the breakers are tripping for no apparent reason. He resets, and all is
fine for a few months.

I suspect something is wrong with the array vs. the breakers needing
replaced.

What should I be looking for and checking?

The client has made sure the breaker screws are tight.

   - Off grid
   - Pole mounted array
   - Solarex 110 w Modules




Regards,
