How Do I Prevent My Classic 150 from Ever Going over 15V?

Zulu,

what happened? is the problem solved? you had people interested..

Yep, looked like folks were zeroing in on the problem.

Remote troubleshooting can be frustrating for everyone.

well it's been over a week... perhaps we dished up a right answer along the way..?

..but,  it would be nice to know what happened
If nothing else but to possibly assist someone who could have similar  issues.

See 2nd last paragraph of my last post -- the "month or so" part.

My RV is in storage, but comes out next weekend, but there are several things I need done before I check on solar. Maybe mid-April.

Don't worry -- I'll keep you posted.

I have had 2-3 complaints of failed inverters in the last week and they where all caused by a bad battery. Some inverters and charge controllers can not regulate and the battery voltage will rise to deadly levels for the inverters. The last one was a bank of L16's that where being charged by a Morning star. One of the L16's failed open and the battery voltage spiked smoking a pair of XW inverters.

The moral to my story is the Classic does regulate "Very" fast and would not cause this destruction but it is apparent that a lot of gear will not regulate very fast if at all. I am going to be excited to hear what Zulu finds when he gets the RV out of storage.

Question is this problem "Always" when connected to shore power? I wonder if the inverters do not regulate well when charging against a fairly open circuit (IE bad battery)

One month later, a new set of 4 Lifelines (courtesy of Lifeline) and it all seems to be working.

I added another panel so I now have 3 Kyocera 245s connected in parallel.

I set a voltage limit of 14.9V and it appears to be working. The Classic is not having issues with my Magnum MS2000 charger -- no faults thrown so far.
