Howdy! “New” Cutwater 24 owner here and sitting in Fossil bay on Sucia island- went to fire up the bbq for a very quick char on some already cooked chicken sausages and as I was using the grill a loud beeping noise came from the inverted switch. I am assuming this meant “turn me off” so I did. Is the inverter designed to be able to use the grill long enough for. A quick meal? Or is is shire power only? If this is the case, would have been way better to just mount a propane grill- just my 2c!! Any help appreciated....Thanks!!
