Installation
‘System overview’
12.1 Installation requirements’
12.2 Wall mounting’
Note:
- When drilling holes in the wall, avoid water and electricity pipes, otherwise it may cause danger.
2.3 Communication module installation’
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 | 6mm2-10mm2 |
| 2 | AC output wire | Two or three polychromatic multi-core copper wires | 6mm2-10mm2 |
| 3 | PV input wire | PV wire | 4mm2-6mm2 |
| 4 | Battery input wire | Battery wire | 4mm2 – 6mm2 |
| 5 | Communication wire | RS485 | / |
Note:
- Please make sure all switches are in the “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.

Post-installation check
| No. | Acceptance criteria | No. | Acceptance criteria |
| 1 | The inverter is installed correctly, firmly and reliably. | 6 | The RS485 communication cable is installed correctly and firmly. |
| 2 | The ground wire connected well and the connection is firm and reliable. | 7 | The cable tie port is trimmed well without leaving sharp corners,meets the requirements of the user. |
| 3 | All switches are in the OFF state. | 8 | All exposed terminals are well protected and there are no vacant ports. |
| 4 | All wiring is correct and securely connected. | 9 | Pay attention to clean up all construction residues. |
| 5 | The wiring of the cable is reasonable, meets the requirements, and there is no phenomenon of broken skin. |
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 switchboard. To shut down your system, follow this guide in reverse order.
Status of PV grid Inverter
Customer can read more information by push the button.
| Mark | Describe | Explain | |
 | Touch mark | Single touch | Switch the display interface or the current number plus 1 |
| Double touch | Enter the setting state or confirm | ||
| Triple touch | Return to the previous display interface | ||
| Long press for 5s | The current data returns to the default value | ||
 | Inverter status indicator | Red | Fault |
| Green | Normal operation | ||
| Red light flashing | 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.). | |||
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.Th 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%.
