So grateful that Carl can debug and fix things!

One day last week, we were cooking several items -- using the air fryer, microwave, induction cooktop, and InstantPot all at the same time. While the microwave is built in to the rig, the air fryer, induction cooktop, and InstantPot are all add-ons to the original items that the rig builders were planning to be used. We had a couple of odd things happen while we were cooking (the light under the microwave went out, everything flashed, we heard a couple of beeps, the refrigerator cycled) -- just weird behavior. We stopped the microwave until the air fryer was done, and everything eventually seemed to get done okay.

Maybe two days later, Carl noticed that the batteries were down to about 39% charge -- the charge button on the remote controller for the inverter/charger would not turn on. Since, when we're plugged in to shore power, the only thing that runs off the batteries are the 12V items (lights, fans, water pump), we usually don't use the charger on the inverter/charger to charge the batteries but rather depend on our solar panels to keep the batteries topped off. Unfortunately, we'd had some very cloudy, smoky, and rainy days, so our batteries had gotten discharged. With the Lithium batteries, we are supposed to be able to run them down to 5-10% without damaging them (unlike lead acid batteries), but we didn't want to test that out.

Carl looked into various things, thinking that there must be an issue with the inverter/charger. 

We found the manual and found that, indeed, there is a in-circuit circuit breaker on the inverter/charger that may have tripped...

The inverter/charger is mounted under the rig on the "roof" of a bay -- of course, not easily accessible. 

So, we cleared out the items in the bay, and Carl got in there...

Sure enough, he found that the in-circuit breaker pin was tripped out. He pushed it back in, and the inverter/charger was charging again!

I'm so grateful that Carl noticed that the battery charger wasn't working and figured out what we needed to do it to get it working again!
