Good day I have setup 2x 15 KVA Quattro in parallel. As soon as we connect grid and the system starts looking after the load it starts “surging” with power ( pushing power from the one to the other). I have made sure that they are both updated the color control is up to date even tried a new cerbo. I also made sure that the input and output ac cablea are the same length. Any suggestions on this topic. Regards Danie
I assume you configured them? With ve bus config
Yes I have done that. In stand alone mode I have no problem with either inverter. Out of the 30 inverter I have programmed in parallel this in my first that does this. I have even set up 12 victrons with no problem…
I would suggest you run the Node Red script here somewhere to see the balance (or imbalance) between the 2 inverters.
One other thing to try: run the inverters in parallel with no load and both AC out open circuit. Check for any phase to phase voltage.
Also, try turning off power assist in both inverters.
