Remote on off for 2 mppt controllers

hi

I have 2 Victron Smart Solar controllers a 100/30 and a 100/50 which both feed a lithium battery bank.

Is there anyway to remotely turnoff the solar when the batteries reach a certain voltage and then turn back on when the voltage drop to a certain voltage, using just one VE Direct non inverting on off cable from my shunt or any other method.

Cheers Dann

The VE Direct non inverting on off cable is the correct way but you need one for each MPPT.

Can you connect 2 VE Direct non inverting on off cables to one shunt, I also need the shunt to activate a latching relay as well, how many connections can you have on one shunt all together.

I have a victron BMV - 712 smart

The relay is rated for 1A, so two of the VE.Direct cables are no problem, they only need a few mA.
So it depends on how big your relay is and how much power that needs.
