3.4 Electrical Connection

3.4.1 Connection to grid (AC side Connection)
(1) Check the grid voltage and frequency if it can comply 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 neutral wire and earth wire
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:
Put the AC cable through the components in this order: screw cap, one-hole sealing ring, insulation body and sheet metal parts.
