Another purchase of professional gear that will complement my existing solar system, is from Offroad Living. Delivered the next morning after OL rang to make sure I would be home, just before Christmas BTW. This fixed 200w solar panel for my Offroad Camper is to replace a competitor brand just out of warranty which never performed well, although a premium price at purchase. The molded, filled diode connection box failed. The competitor when approached said sorry 3 years warranty is up so can't help you. Nil customer service. Customer service has always been perfect at Offroad Living. I was amazed at a phone call the next morning to ensure I had my panel delivery secured.
