Inverters operating in parallel with shore power should not have the output __________ at the inverter.

Inverters operating in parallel with shore power should not have the output neutral grounded at the inverter. This is crucial for safety and operational integrity.

When inverters are connected to an AC power source, such as shore power, they operate in a manner similar to other generators. The grounding of the neutral at the inverter can create multiple grounding points in the system, which can lead to unwanted ground loops and potentially hazardous conditions. It can also interfere with the proper functioning of protective devices, like circuit breakers, and could affect the system's overall electrical performance.

By ensuring that the inverter's output neutral is not grounded, you maintain a consistent grounding scheme throughout the system, which helps to prevent ground faults and ensures that any safety devices will operate as intended. This is particularly important in marine applications where electrical safety is paramount, and adherence to ABYC standards is required to ensure the reliability and safety of the electrical systems onboard.
