There is current in the neutral line of the photovoltaic inverter

To an Engineer: A "neutral" is a current-carrying conductor that carries the unbalanced current in 3 phase systems, and is intentionally connected to the ground. In North America, the neutral is color-coded white or gray for easy identification (see image below). To a Developer or Owner: A neutral means 4 wires instead of 3, AKA increased cost!
