I’d put my money on the batteries are getting really bad. The easiest “fix” is to put say 10’ of #6 between the CC and the battery connection. It will probably keep the surge down to below the CC breaker trip point. boB at midnite suggests you actually wire it to the battery and not the main battery buss in the XW box. The reason is for more wire, to help dampen the surge that is put onto the CC Hope this helps
