In August I ordered a Midnite Solar Mini-DC Disconnect and last month I finally got time to install it into my PV system. The Mini-DC is a small breaker panel/enclosure specifically targeted PV systems like mine. The enclosure has one 250A breaker and room for five small, DIN-rail breakers as well as mounting holes for the shunt(s). Below is an image of the rewired system and a close up of the Mini-DC.
