4.3 Electrical Connection

4.3.1 Connection to grid (AC side Connection)
1. Check the grid voltage and frequency to see if it can comply with the required voltage and
frequency of the inverter connection.
2. Add a 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 neutral
wire and earth wire is less than 10ohm.
4. Disconnect the breaker or fuse between the inverter and the utility.
5. Connect the inverter to the gird as follows.
