Understanding the concept of a "Neutral" conductor is essential to the success of your solar + storage project. To an engineer, a neutral conductor is a current-carrying wire that balances the unbalanced

Perspective: From my experience auditing residential and commercial PV projects, nothing creates more confusion than how to handle grounding, bonding, and isolation at the inverter.

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

The inverter says it has a neutral to ground bond switch that will activate or deactivate depending on if power is coming from the generator or the batteries. This option can be completely deactivated

The inverter powers critical load in the house during the day using solar energy, while non-critical load is powered over utility. Both critical and non-critical loads share the same neutral line.

That depends on the design of the inverter. But it shouldn''t be a problem. As the neutral is considered the "common" side of the two systems. A diagram of your wiring plan, would help show

The code requires neutrals to be grounded but that''s not what makes it a neutral. What makes it a neutral is that the vector sum of the voltages to the phase conductors is zero (ideally, or
