That\u2019s fine and well, but when asked directly, Sonnen didn\u2019t have a part # for the contactor and suggested that anything over 150V DC would be difficult to find. Anyone know of a 600V rated contactor that would suit the bill? Essentially the contactor would need to sense grid interruption (via a 15A-AC breaker) and open a 600 V rated DC string. </span></span><span style='font-size:13.0pt;color:#454545'><o:p></o:p></span></p><p class=p2 style='margin:0in;margin-bottom:.0001pt;font-stretch:normal;min-height:20.3px'><span style='font-size:13.0pt;color:#454545'><o:p> </o:p></span></p><p class=p1 style='margin:0in;margin-bottom:.0001pt;font-stretch:normal'><span class=s1><span style='font-size:13.0pt;color:#454545'>I\u2019ve done some preliminary searching and have come up empty handed.
