The plug had melted plastic on one prong so I had to use pliers to get the plug out of the outlet. I scraped the melted plastic off the plug and inserted it into the other outlet. It worked. Circuit breaker should have protected the inverter before the plastic melted. Mine is an older unit than the KAR but it is a Giandel 24v 4000 watt.
Full review / responsesIt has worked flawlessly so far. Giandel technical support was excellent at answering my technical questions prior to purchase. The technical support pre-sale convinced me this brand is a cut above the typical cheap brands on Amazon, etc. I'm very satisfied at the quality and performance for the price point. My only complaint is the display is not bright enough for a shaded outdoor space on a sunny day. Technical support explained that they had too many complaints the display was too bright at night inside RVs, so they reduced the brightness.
