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></div><div style="margin: 0px; font-size: 17px; line-height: normal; color: rgb(69, 69, 69); min-height: 20.3px;" class=""><span class="s1"></span><br class=""></div><div style="margin: 0px; font-size: 17px; line-height: normal; color: rgb(69, 69, 69);" class=""><span class="s1">I\u2019ve done some preliminary searching and have come up empty handed.
