This grounded conductor is called the “Neutral / Cold / Return”. As this conductor is bonded to earth ground, it will be at near zero voltage or potential. There is no risk of electrical shock if this conductor is touched. The other current carrying conductor is called the “Line / Live / Hot�
The inverters have no input neutral, only L1, L2, and G inputs, with L1, L2, G, and N outputs, with the neutral being center tapped on the transformer. The manuals all say the

Likewise, for a 3-phase load network acting like 3 identical impedances connected to a (foating) neutral point, the neutral point voltage becomes the average of the three phase voltages.

Eliminating the Neutral: Some three-phase string inverters do not require a neutral conductor to operate. This is due to the fact that PV inverters typically output balanced three-phase power,

The output phase to neutral voltage pattern is simple to understand. To cite an example, consider the initial time interval (0 to π/3) when g1 and g6 are active, causing Vs to emerge across

Most inverters now these days have the FG or G connection as well as a neutral for internal ground fault protection. I am going to assume that the above circuit is simplified, because the normal isolation control
