For the sizing of a 3 phase Y system using a transformer, I need to compute the three phase AC power.
In the Parallel, split- and three phase VE.Bus systems manual, the power of the inverter/charger are just added up. For example, Using our 15kVA Quattros, the maximum system size is a 180kVA three phase system. Which then consists of four units on each of the three phases: 12 units in total.
I can understand that this is written in a way to make clear what the maximum system configuration looks like.
But the "true" three phase system power would be 15kVA * 4 * SQRT(3) = 104kVA, taking a power factor of one for simplification.
Am I correct or do I misunderstand something completely wrong?
