What is the connection between N and PE during inverter operation?
Connection between N and PE during inverter operation. - The ground relay is useful when an earth-leakage circuit-breaker is part of the installation. When the internal transfer switch is open (inverter mode) the Neutral of the inverter is connected to PE.
What are inverter settings?
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.
What is the output voltage of an inverter?
Reviewing the specifications and the schematic diagram on the bottom right of pg 1 of the Inverter spec., the output voltage of the inverter is going to be 220 VAC to 240 VAC (50 Hz or 60 Hz per your selection). The schematic has a 2 wire output and a chassis ground. One of the 2 output terminals is labeled "P" and one labeled "N".
What voltage is a 2 wire inverter?
The schematic has a 2 wire output and a chassis ground. One of the 2 output terminals is labeled "P" and one labeled "N". Service voltage at your home is 220/127V 3 phase, 4 wire, so phase-to-phase voltage is 220v which matches your inverter output.
Can I connect a N terminal to a 2nd phase inverter?
I would not try that without consulting the manufacturer! If the "N" terminal on the inverter is not bonded to the ground but is "floating", you could most likely connect the "N" terminal to one of the 3 service phase legs and the "P" terminal to a 2nd phase leg and the inverter would then supply 2 of 3 phases of your house distribution.
Can I connect a grounded inverter to an ungrounded service voltage?
The Neutral of your service voltage is grounded and the 3 phase legs an not grounded, so you cannot connect a grounded inverter output to an un-grounded (but referenced) service voltage phase or you create a direct short circuit.
