Not all MPPT controllers do this. We took great pains to stop this in
the Classic. But even then there could be a wind turbine or something
hooked direct that could cause this so I could see a possible need for it.

I want to understand the issue if you don't mind. Are you saying that an
MPPT charge controller has no voltage limits? I would have presumed a CC
would know that there is no batteries attached.
From your email, you want a device that will measure the CC output voltage,
and shut it down if it

Yes some charge controllers regulate pretty slow. So if the battery goes
away on them they can skyrocket in voltage on there battery side before
they can catch themselves. This may only be for 2-3 seconds or so but
that is all it takes to send an inverter up in smoke.
This is also the
Has anyone tried using a battery management system (BMS) like those used on
electric vehicle battery banks? Here is an example:

This has been happening all too frequently here. We live in a big area
of off grid homes, dozens of systems.

Hi Dan,
You can do it!
You are looking for a circuit called a crowbar. It is a SCR that turns
on when a certain voltage is exceeded. Typically implemented with an SCR
and a zener diode. The SCR, when turned on, shorts out the battery. And
BAM you blow the big fuse in the battery bank or
