It looks like the charger (with 1860) has frozen again. I won't know for sure until I visit my property again, but the charger isn't spitting out any serial data anymore.

take a look here

I visited my property this weekend and confirmed the kid wasn't working again. Batteries were still up at 25.4v thanks to a PLC shutting off loads when no charge current was detected for 3 days. Unlike the last time when the kid froze, this time it appears to be completely dead. There was no text on the LCD when I arrived, and disconnecting/reconnecting from the batteries and solar didn't do anything.

I'll be starting a ticket with midnite and will report back how it goes.

December 2018 Update

Midnite gave me an RMA, and I shipped the Kid back for repair. It was still under warranty so there was no charge (other than my shipping cost). Midnite repaired it and sent it back within a few days. I must say, excellent service. The reason for the failure: "It had a blown main processor." I inquired further, but the answer was about as I expected;

"Hard to say what blew out the processor.  Could have been loose solder joints on the circuit board caused by shipping/handling.   Could have been voltage spike on one of the circuits to the processor.  A resistor was replaced too.  This particular resistor blows when the processor blows, so that doesn’t help narrow down the root cause.  Sorry, just no way of knowing in cases like this."

I'm hoping that the failed processor was due to something rare, but only time will tell. I bench tested for about 3 months with no issues, and just recently returned to my property to wire it back up again. No issues so far (fingers crossed).
