Since about one year I have been operating a self built battery with one multiplus II 5000VA an now I want to expand to a 3 phase system with three multiplus units. Currently I have wired the remote on/of to a kind of emergency stop button in order for other people to be able to shut the system down…

Rather than trying to use the remote on/off for each inverter, the recommended solution is using the safety switch assistant as described in the below post: [image] Quattro's won't stay off when using remote connector Q&A and troubleshooting Hi @LucGH , Have you tried usi…

No you can not wire them in parallel! You need either a safety stop switch with multiple break contacts, build something with a relay or use the safety assistant However in 3 phase setup they all shut down when using the remote on off on master I also use 2 safety switches for my system (1 in mai…

The GX will overrride the remote on off in any case. The safety switch assistant is the way. And it only wired to the master so simplifies things. Depending on if you are classing this as an emergency stop or not, you will also need a way to shut down PV production otherwise there will still be cur…

Thanks a lot for your kind answers! So I’m considering to: use the normally closed switch (that opens on pressing the switch) in my safety stop to activate the remote on/off on the master (L1) inverter. use the normally open switch (that closes on pressing the switch) at the same time to wire to …

In most cases the assistant should only be used in the master of L1, and you can define which input to use and whether it should be open or closed to activate the assistant (see below). [image] [image]

You can program it how you want.

Thanks a lot! I’ll try the safety switch assistant as soon as I have everything wired up!

Just confirming that the safety switch assistant does work for everybody who might consider using it. During setup you can choose what type of connection needs to be broken or made in order for the safety stop to take effect! As a bonus you get a nice blinking LED experience when you activate the sa…

WARNING: for everybody considering to use safety switch assistant: do not use AUX1 as the input because this is interfering with settings for the grid code where AUX1 is used to prevent grid feed in. It took me quite some time to figure out why my multiplus was not discharging the battery anymore a…

Its a bit of a quirk to do with the code for grid. Not even a question i thought to ask about either. Ve config the assistants are no AI lol. It is neat there are options to make it work otherwise with other inputs. Yeah the blinking lights are a bit of fun. Thanks for the update though.
