Neutral Conductor Value Engineering in 3-Phase String-Inverter Systems
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, many allow the

Transformer Neutral required for Inverter Interconnection?
The neutral on the PV side is derived in the windings on that side and has nothing to do with the neutral on the utility side. Some people come across more high leg delta than others.

Utility Input Neutral connected to Inverter Output Neutral....or
A lot of grid-interactive inverters (most, in my experience) have all their neutrals going to a common internal neutral bus bar, and only require 1 neutral connection back to the panel''s bus that
