Yes I understand the voltage difference b/w L1 and neutral and L2 and neutral as well as L1 & L2.
I meant when it comes time to connect an inverter to the mains panel. The inverter has clearly marked L1 and L2. But the mains panel doesn't. So I wondered if there was a precise way of pairing InverterL1 to XMainsPanel and InverterL2 to YMainsPanel.
Theoretically there is a difference because when one phase is "up" the other is "down", correct?
But does it make a difference when connecting them?
