Hi, I've got an off-grid solar/generator system as shown in the photo below (not set up by me!).
Currently the Inverter and BMV-700 are both connected to a relay from the generator, and they can both start/stop it using their own independent conditions. I have a Venus GX installed but currently its not connected to the generator, and just monitors what the Inverter/BMV are doing.
Ideally I'd like to connect the Venus GX to the generator relay as well so that it can be controlled fully, and remotely more easily. I think I've figured out where to take the relay wires from in order to do this (see second photo).
My question is this: what is the correct way to wire to the Venus GX. I understand that 'Relay 1' is for the generator, but I don't know which wires go to which terminal (NO / COMM / NC).
Secondly - how do I do this safely without risking shock or injury? (i.e. how do safely disarm the wires before I re-connect everything up).
Thanks,
Michael.
