Inverter Settings 1. To set output voltage of inverter - This is normally 230 Vac. Possible values 210V ~ 245V. 2. Used to enable/disable the internal ground relay functionality. Connection between N and PE during inverter operation. - The ground relay is useful when an earth-leakage circuit-breaker is part of the installation.
Connecting the N and PE lines together can provide a stable reference potential for the inverter, ensuring the stable operation of the system. This connection method can also prevent system voltage drift, especially when there are large load changes or inductive loads in the system, which helps maintain stable voltage output.
It’s important to note what this means: In order for an inverter to put out the rated amount of power, it will need to have a power input that exceeds the output. For example, an inverter with a rated output power of 5,000 W and a peak efficiency of 95% requires an input power of 5,263 W to operate at full power.
This article first introduces the basic concepts and functions of N-wire (neutral wire) and PE wire (protective grounding wire) in electrical systems, and then explores in detail the reasons why N-PE must be reliably connected in off grid states of hybrid inverters, including safety, system stability, and regulatory requirements.
Our photovoltaic systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
Example: Neutral-point clamped inverters (also called ”diode clamped” multi-level inverters). Active switches are sometimes used instead of diodes (Active Clamp NPC inverter, …
