Wrenches,
We have a few jurisdictions in the Bay Area that still require rooftop DC disconnects. We are installing a lot of SMA TL-22 inverters with dual MPPTs and if the system has more than 1 string it has been hard to source a good disconnect option (need 4 poles for switching two ungrounded strings). Does anyone have a good DC disconnect idea for this application? Best, August Luminalt
