<meta http-equiv="x-dns-prefetch-control" content="off">In response to this: "Luckily the latest inverters from most manufacturers take care of this need with their included/integrated but seperated fused DC disconnects....." <br><br>I actually wish the integrated disconnects for the new inverters were an option when purchasing, i.e. when I order the inverter it comes with it automatically, and is therefore reflected in the price. Where I live the AHJ and utlities are requiring the handled-lockable-'regular' AC and DC disconnects regardless of whether or not there is a UL-listed integrated disconnect with the inverter. Alas, for me it is redundancy and extra cost for materials and electrical work either way. I can either have the electrician wire it up and pay their cost, or I can leave the integrated inverter out (when it is listed as optional in the installation manual) but now I have a non-returnable part sitting around, which is wasteful too. Alas,
the best solution is more solar so everyone becomes more familiar with it!<br>
