Hi, new to the site. I have four Renogy 100w panels that I'm going to mount on our travel trailer that has a Zamp box on top with three ports. I understand that the Zamp plugs are reverse polarity to most other connectors. I haven't received the panels yet so I'm not sure whether they have bare wires or MC4 connectors (and Renogy has not replied to an email I sent). Is there a simple way to convert to the Zamp plugs from the panels or should I think about replacing the whole box and hardwire the wires in another junction box? Thanks!
