How can I protect control boards from over DC voltage
Can I use something like this DORK buck ? I am thinking in the event if my converter fails and voltage goes high of I don't isolate batteries before I equalize them.

If the never exceed voltage on the refer board is 15.4V, I suspect I would not be doing it any good over time to be sending it 15V.
Easiest is to pull fuses on the furnace and refer as mentioned and as I did yesterday. The refer board failed for unknown reasons and I am now fairly certain I equalized while it was on. Failure wasn't at that time but within 2 weeks of equalizing. (I really should keep a log book). We'll never know the cause of failure.
I equalized because I like to occasionally shut off my converter and check my battery capacity. A boondock test if you will. I have 3 each group 24 batteries, new in July. I shut off the converter and let the batteries stabilize at 12.7. I used some lighting (all LED). After two furnace cycles voltage holding 12.4 just before the third furnace cycle. I felt it wouldn't take very many cycles before the voltage was at 12 volts. It certainly wouldn't get me through the night. My battery tools (hydrometer and battery capacitance tester) are home in AZ and I am working out of my toy hauler in NM. I felt it wouldn't hurt to equalize while the sun was high.
