3.4 Electrical Connection
3.4.1 Connection to Grid (AC Side Connection)
(1) Check the grid voltage and frequency, select a suitable safety standard from inverter that comply with this requirements.
(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:
