The system is configured with two 10K Quattros 120V/240V Split phase with 4 SmartSolar Charge controllers, a Lithium Battery with a CAN-bus BMS and it also has a Lynx Ion Shunt.
I would like to have a Smoke/Fire Alarm external NO or NC relay contact ask the Venus GX to put all Victron equipment is shutdown mode (Two Quattros and four SmartSolar) and if posible ask the BMS to shutdown the battery internal relay.
Is there a way to do with when ESS is been used.
As for the MPPTs could you place a relay on the PV input side, prior to MPPT connection, as a signaled disconnect from the Venus..?
I know the Multi's can use an input for a safety switch, but don't think MPPT's will react to this...
Good question!
If there is a ESS assistant running on Multi and on CCGX then all MPPTs will goes down when Multi switches off
Are you saying that if the only Assistant is the ESS assistant in our case. And I use the internal Remote switch connector inside the Quattro. Once I open the circuit the Quattro will shutdown and the Venus will tell the SmartSolar Controller to shutdown aswell?
Since have a 120/240 Split Phase setup, would I have to open the remote connector in both L1 and L2 Quattro. Or would the master L1 be sufficient to shut the whole system down?
Thanks

I wonder if the birdhouse from Midnite might perhaps be relevant?

I use a NO with the inverter safety switch assistant.
And the NC for the mppt remote switches.
Hit one button the inverters go off so no discharge from them and the mppts stop charging.
Then the users pull the NH fuse disconnect if there is time and walk out.
