[RE-wrenches] Combining Multiple Inverters

[Glenn Burt]

Code requires OCPD on the output of each inverter, so not sure where the savings would be..

I am curious about best practices for combining the output of multiple
inverters:

   - We are considering using an insulated tap "Polaris/Burndy" connector
   in lieu of a solar accumulation panel. We would then run the output of this
   tap connector through a fused disconnect and on to the interconnection.
   Does anyone else do this?
   - In the above scenario, how should we size the wire between each
   inverter's output and the tap connector? Since there is no OCPD on this
   wire, would we have to use the same wire gauge as the combined output? or
   can we get away with sizing each wire according to its associated inverter
   output rating?
