4.4 Electrical Installation

4.4.1 AC Terminal Connection
1. Measure the voltage and frequency of the grid-tie connection point to confirm that it meets the
grid-tie specifications of the inverter.
2. It is recommended to add a circuit breaker or fuse on the AC side, whose specification shall be
more than 1.25 times the rated current of the AC output.
3. The PE wire (ground wire) of the inverter must be reliably grounded.
4. Disconnect the circuit breaker or fuse of the inverter and the grid-tie connection point.
5. It is recommended to use copper wire. If you need to use aluminium wire, consult the inverter
manufacturer.
6. Follow the steps below to connect the utility service and the inverter.
Note: Do not connect copper blocks with aluminum wires. Otherwise electrochemical
corrosion will occur and the equipment will be damaged.
• Use copper terminals for copper wires and copper-aluminium terminals for aluminium wires.
Aluminium terminals cannot be used directly.
• Please protect the stripped part with a heat shrink tube after stripping the cable.
Step 1: Select a suitable AC cable and strip the wire.
For specific specifications, refer to the table below.
