Hi,
I have an installation with 6 x Quattro 48/15000 inverters (3 phase, parallel) and a Cerbo, due to the installation size, I added an Emergency stop button into the system with 6 contacts on it, one for each inverter. Then I removed the remote on/off bridge that comes factory fitted in the inverter and wired a separate NC contact of the E Stop to each inverter ( 2 separate wires to each inverter)
When operating the E Stop, all inverters turn off as they should, but around 10 seconds later, they all came on again for around 10seconds then off again and the cycle repeats while the E Stop is engaged.
Just wondering if anyone can provide any advice on why it is doing this and not just remaining off when each of the remote on/off terminals are open circuited?
