I know very little about 3 phase, if it gets to 3 phase my hamster doesn’t even try to stay on its wheel.
Common sense tells me that the 3x 15 kVA Quatro’s in single phase will actually be more redundant than the 3 phase Multi config?
Should you lose a Quatro you are down to 30 kVA and you can simply manage loads for that week or 2 how ever long it takes to get fixed or swopped out.
However should you lose a single Multi in the 3 phase setup you basically have to drop the entire phase since it will be out of balance with the rest. Or I guess you can also switch off Multi’s on the other 2 phases just to balance things out again?
Planning to move to a farm with a 3 phase supply in future, this is something I really have to start getting my head around. As die ouens begin 3 fase dan voel ek sommer dom.
