3 Phase Emergency Stop control

Hi! - Unattended 3 Phase Off-grid Hybrid Multis & BYD system

What's the best solution for installing an emergency OFF switch on a 3 phase system?).

Am I right in thinking the Safety Switch assistant can be used only on L1 with L2 & L3 also switching OFF as they will become unsynchronised and go into an error state?

And what's the best way to restart the system remotely after resetting the Emergency switch on site?

Thanks in advance, Marc

@Stad

Using the safety switch on L1 the entire system will switch off. And all the lights flash on all units.

Errors you will see will be error 3 and error 10

If the emergency switch is released the system will restart. So start up procedures will be needed if there are high/complex loads.
