I had a similar situation in Minnesota, my local inspector was puzzeled but the
regional inspector said ABSOLUTLY the solar equipment has to be shut off with
no more than 6 motions of the hand. I combined the AC into a panel of 12
breakers, with one main (i had 12 inverters). For the DC side I did something
DT but I could have used 2 each 6 pole Square D 600 volt 30 amp Disconnects
or 3 each 4 pole, or 4 each 3 pole to complete the disconnect requirement

Subject: [RE-wrenches] 690.14 (4) Max Number of Disconnects
Hi Wrencher’s
I am working on a system with 10 inverters. The output of all 10 single phase
inverters will be combined in a main lug only panel located on the 8th floor
(each inverter will have a 2 pole breaker). The MLO Panel will be protected by
a fused switch located in the basement. Does the panel on the 8th floor used
to
combine all 10 inverters need to have a main breaker in order to comply with
690.14 (4)?
Any and all feedback is appreciated.
