3. Electrical connection
Please prepare the cable before connecting as follows.
| No. | Cable name | Type | Recommend model |
|---|---|---|---|
| 1 | Protective grounding wire | Single multi-core yellow-green wire | 6mm² |
| 2 | AC output wire | Two multi-core or three polychromatic copper wires | 6mm² |
| 3 | PV input wire | PV wire (such as PV1-F) | 4mm² – 6mm² |
| 4 | Communication wire | RS485 | / |
Note:
- Please make sure all switches are in “OFF” position before wiring. For personal safety, please do not operate with electricity.
- If the diameter of the cable does not match the terminal, or the cable is aluminum wire, please contact our after-sales personnel.

| Note:
- Before installing the PV terminal, please double-check that the PV input voltage and current do not exceed the MPPT limits.
- When installing the PV terminal, pay attention to the difference between the positive and negative poles and the one-to-one correspondence between the terminals and the machine.
- There is a “click” sound when the terminal is connected,please gently pulling the PV wire to make sure there is no loose or pulling off.

6. Power on and off steps
Note:
Before turning the inverter on, please make sure the PV input voltage and
current are within the MPPT limits.
Follow the steps below to turn the inverter on:
- Switch on the build-in DC isolator at the bottom of the inverter.
- Switch on the PV Array and DC isolator next to your inverter, if you can not find this switch, skip this step.
- Switch on the Solar AC isolator if the inverter is more than 3 meters away from your switchboard.
- Switch on the solar supply main switch in the switch board.
To shut down your system, follow this guide in reverse order.

Warning
It can display the basic information of inverter through LCD display screen (PV/AC voltage, PV power, AC current, total power, generating capacity, etc.).
8. Export limitation setting
If the local grid company requires to limit the output power from your inverter systems, we introduce the concept of Export Limit Rate. The ratio of your system output power divided by the rated power of the inverter is called Export Limited Rate. For example, if the local grid company only accepts 4kW from your 5kW system, then the Export Limit Rate of 5kW inverter should be 80%.
