4.3 Electrical Connection

4.3.1 Connection To Grid (AC Side Connection)
1. Check the grid voltage and frequency for whether it complies with the required voltage and
frequency of inverter connection.
2. Add breaker or fuse to AC side, the specification should be more than 1.25 times of rated AC
output current.
3. The PE line of inverter should be connected to the earth, make sure the impedance of the
neutral wire and earth wire is less than 10 ohm.
4. Disconnect the breaker or fuse between the inverter and the utility.
5. Connect the inverter to the grid as follows:
There are 2 AC connector brands for inverter, VACONN and WIELAND.
6. The AC line construction shall be such that if the cord should slip from its anchorage, placing a
strain on conductors, the protective earthing conductor will be the last to take the strain. As
such, the PE line is longer than L and N.
