Victron MultiPlus Compact 12/2000/80 charging issue

When arriving at my boat this afternoon, I noticed that my Victron Inverter/ Charger had shut itself off. After reseting it, I noticed that the volt meter located at my Nav Station on my Lipari, was only reading 11.9V, indicating two things. 1. The batteries were dreadfully low on charge, and 2. the charger was not doing its job as I would expect to see closer to 14V when in bulk charge mode. After checking all of my breakers, I decided to run a test. I started the engines and the volt meter immediately jumped to 14V. The remote control panel for the Victron continues to show that it is in the bulk charge mode.

One thing in the manual caught my eye. It said if the batteries are not charging, but the unit is up and running without showing a fault, to check the 30 A thermal circuit breaker and reset it. Since it has been consistently over 100F this summer, my thinking is that this may be the culprit. Only problem, I can't find it! Can anyone tell me where this 30A breaker is located? I pulled the front panel off and I see nothing that even remotely looks like a breaker.

Measure the voltage at its output. And check your battery fuse (should be a 300a class t) and inverter switch. If you blew the inverter fuse. You would have 14v at charger output and 12v at. At battery.

If it had a 30a fuse that would be in the ac side. If it's showing bulk charge the ac input is getting through.
