Victron Battery Protect no longer recommended

I was just curious how many people here have the Victron Battery Protect in their system along with an inverter.

Based on what I've been reading, I'm pulling mine out quickly so as not to burn the rig down.

Victron has now changed their installation manuals to indicate that the BP should not be hooked into a system with an inverter. They apparently knew this all along, but their business used to be primarily through people who know this stuff better than the average solar-power buyer, and who already knew that you shouldn't do this - and so they're starting to make their instructions amateur-proof.

Just wish they had noted this before I bought one.

Most inverters have a low voltage shut down built in.

Use it for standard house loads, besides the inverter, in case you leave something on.

First, Victron amended their manual for the BP - they added the following:

"The short circuit protection of the SBP will be activated if you try to directly connect loads with capacitors on their input (eg inverters). For that use case, please use the SBP to control the remote on/off switch on the inverter, instead of disconnecting the higher power DC line."

(See here: https://www.victronenergy.com/upload...T-ES-IT-TR.pdf at item 4.)

Victron techies are telling people not to use the BP in any circuit containing an inverter. I'm no EE, but I think they're saying the huge current surge of loading the capacitors fries the mosfets in the BP. It might merely make the BP inert - i.e., providing no protection without telling you - or it might melt and burn.

I had originally wired my BP directly after the shunt, and in line with both my DC loads and my inverter leads. Apparently, you must instead pull the inverter off of the BP line. To me, this limits the effectiveness of the BP, as it will no longer shut down everything in the face of low voltage. You can rely on the inverter's low-v protection, but the BP is out of the equation.

Will Prowse has also gone through his old vids and comments and now recommends NOT using the BP.

There are ways to keep the BP. You can use the remote-switch function of the BP to trigger the inverter off (if your inverter has that switch-off function built in.) I'm looking into that (as I'd rather not simply throw away the BP) but I'm not that far yet.

But it does seem like Victron and Prowse are both saying, fire hazard with a BP and an inverter. So I thought that maybe the better solar-educated minds here might want to explore.

(ETA) I should add that this is in addition to the bi-directional problem dealt with here: https://community.victronenergy.com/...fire-if-y.html - that indicates that your solar charge controller must not be wired such that it passes charging current back through the BP.
