Is it possible to switch Multiplus 800/35 inverting off when SOC reaches 50% via Cerbo GX?

I have just added a Cerbo GX to my current installation consisting of two 12V 190Ah AGM batteries, two Blue Solar MPPT 100/50 controllers, one Multiplus 800/35 inverter/ charger and a BMV-712.

Prior to adding the Cerbo, the original system protected the batteries by switching off the inverter when an alarm for 50% SOC was triggered via the BMV relay that was connected to the remote connection of the Multiplus.

I had to remove the remote connection (DS1 to "off") in order to allow the Cerbo to properly connect to the Multiplus via VE.Bus.

I now want to reproduce the same protection rule using the Cerbo. Is it possible?


Thanks in advance.

Hello @fede_h , I think that when you load the 2-wire BMS assistant you can use a Sense V or T for remotely switch OFF inverting.

Hope this helps.

Best regards, Rob

Hi @Rob Fijn , thanks for your answer. My installation is now 1600 km away and I had to disconnect my multiplus from the network but I will try that when at the site. Thanks again.
