When I was looking at the Outback Flexone setup today during some down time I notice that they send that package out with an 80A PV breaker and an 80A GFDI breaker. If a person had an array up at 2500W and a 24V battery bank, on some occasions, wouldn't this lead to tripping of the 80A breaker on the output side of the charge controller?
