Switch Bluesolar MPPT Charger connected to venus os off if Two signal Lithium BMS is connected to MultiPlus

Hi,

I have a MultiPlus 12/3000 with a Lithium battery with 2 wire BMS connected to the MultiPlus.
The switching of the MultiPlus from the BMS works great.

There is also a Venux GX, a BMV 712 and multiple BlueSolar MTTP 75/15 charger in my system.

It would be great if the MTTP BlueSolar Charger switch the load off, if the BMS disable allow-to-discharge signal on the MultiPlus. Same thing with the allow-to-charge signal.

Best regards,
Rainer

I support this feature but would like the function to be optional - as the 2 wire BMS assistant can also be used as means to control the Multiplus only.

Hi, i already asked in "questions and answers" forum but my question correspond exatly at this idea.

For a quattro victron, i would like to know if this option is already possible if we program K1 in according to the state of AUX1 for charge and program K2 in according to the state of TEMP for load.

below a schematic to explain well :

Meanwhile can this not be be (more simple) achieved by using the relays from the BMS to drive a DPDT relay and simply connect both the Quatro as well as the BP-65 to that?
