I have not, but I had the same thought after a few days of thinking about the situation. From memory, I recall the inverter's overload light came on. These are three Amperetime 24V 100 AH batteries, paralleled onto a bus bar, so it's not like I can look at a screen or BMS info. This is the first and only thing I've tried with this inverter that won't run, so it doesn't warrant too much additional exploration in light of the mountain of other things I need to get done. But if/as I get more info, I'll try to make sure I report back. Thanks for the idea.
