We have done one Solark installation & I was shocked as to the lack of ground wire landing terminals & space. We added a 12126 metal box below to ease the # of entrances to two 11/4”. I jumpered a # 8 to a second ground bar to allow for additional landing locations. I called Solark to question this & the response to the question was “yeah we have heard this from other installers “. End of call. Dana Orzel C: 208.721.7003 E- d...@solarwork.com
