Going through some testing on a recent install. 3 Quattros (15k) in 3-phase config. If there is a small load, i.e. 3kW, and the device is set to 'Off' from 'Inverting' on the Cerbo GX menu, supplied voltage seems to go crazy for a fraction of a second (contactors bounce, lights flicker, etc) before the inverters switch off. All loads on AC-1 out.
No such behaviour happens if I open the contactor under load between AC1-out and dist board, and switching on under the same load exhibits no bad behaviour
is this expected?
