I have a three-phase off-grid system with 6 Quattro 15kva, 172 kwh pylontech battery and 60 kva generator that gives me the following problem. when the gen is running the power on the ACIN1 input varies continuously very quickly with constant AC load. In addition sometimes the generator has not been able to connect to the Quattro: it connects in parallel for a few seconds and then switches off immediately. We connected the generator directly to the load, without going through the victrons and it works perfectly. Can anyone help me? Thanks in advance
