I don’t have one of those but I have used Mars lights and if your issue is that nothing happens or if one or more panels are out when powered and switched on take a look at the cable assemblies. It looks like the wiring package used utilizes the same type of splice points they use in their other lights, I have found that they tend to under strip, over insert and under tighten the wiring in those splice points. If you open up the splices and just redo the connection points it will probably sort you out.
