Hello.The datasheet of inverters specify the peak power. How long does this peak last?
From my experience with different sizes of inverters (5, 10 and 15kVA) on the quattro range from both 120 and 230V ranges, I can confidently say and I have tested this several and enough times to say that the quattro range does not reach the peak power being twice the nominal power at all and any load just above the kVA P30 rating overload the inverter instantaneously. I am really interested to see test and real data from Victron proving that these inverters reach peak power.
Therefore, I do not recommend to design any system taking the peak power into account as you will end up with inverters overloaded, trust me.
The quattro range is a great product but to me, without any doubt, this is their weakest point in comparison with their competitors on industrial application.
I found your comment while searching for definition of "peak power" for our 15KVA Quattro. Do you think your experience with the quattros that it cannot handle more than P30 would also apply for very short power peaks (0.3 sec)?
Background: We are defining a system with 50-70% standard load as average (K=0.95). By adding a new planned x-ray device it would be a few times 130% for duration of 0.3s per hour (every time a x-ray picture is taken). I am concerned that this might kill the Victrons over time.
