William,
I see now from the separate post from Michael Kelly of Solectria that indeed you cannot combine your two strings with this inverter. I think that leaves you stuck with four separate disconnect switches unless someone on this list knows of a four pole DC rated disconnect switch. Or, you’ll have to switch inverters. I have never installed these Solectria inverters so I don’t know much about them.

I believe the Solectria you are using has two MPPTs? Ideally, you would keep each string separate to benefit from the dual trackers – this would mean four DC disconnects if you went with a standard product like a Square D HU361RB. If you combine each of the two strings out at the array(s) then you could get away with two disconnects, one for each inverter. Neither option is ideal. Best, August Luminalt
