Installation Precaution
This Hybrid inverter is designed for outdoor use(lP65), Please make sure the installation site meets the below conditions:
- Not in direct sunlight
- Not in areas where highly flammable materials are stored.
- Not in potentially explosive areas.
- Not in the cool air directly.
- Not near the television Antenna or antenna cable.
- Not higher than the altitude of about 2000 meters above sea level.
- Not in an environment of precipitation or humidity (>95%)
Please AVOID direct sunlight, rain exposure, and snow laying up during installation and operation. Before connecting all wires, please take off the metal cover by removing
the screws as shown below:
Considering the following points before selecting where to install:
- Please select a vertical wall with load-bearing capacity for installation, suitable for installation on concrete or other non-flammable surfaces, installation is shown below.
- Install this inverter at eye level in order to allow the LCD display to be read at all times.
- The ambient temperature is recommended to be between -40~60“C to ensure optimal operation.
- Be sure to keep other objects and surfaces as shown in the diagram to guarantee sufficient heat dissipation and have enough space for removing wires.
For proper air circulation to dissipate heat, allow a clearance of approx. 50cm to the side and approx. 50cm above and below the unit. And 100cm to the front.
Mounting the inverter
Remember that this inverter is heavy! Please be careful when lifting out from the package. Choose the recommended drill head (as shown below pic) to drill 4 holes on the wall, 82-90mm deep.
- Use a proper hammer to fit the expansion bolt into the holes.
- Carry the inverter and hold it, make sure the hanger aims at the expansion bolt, and fix the inverter on the wall.
- Fasten the screw head of the expansion bolt to finish the mounting.
3.3 Battery connection
For safe operation and compliance, a separate DC over-current protector or disconnect device is required between the battery and the inverter. In some applications, switching devices may not be required but over-current protectors are still required. Refer to the typical amperage in the table below for the required fuse or circuit breaker size.
| Model | Wire Size | Cablel (mm2) | Torque value (max) |
|---|---|---|---|
| 5 Kw | 2 AWG | 35 | 24.5 Nm |
| 6/8 Kw | 1 AWG | 50 | 24.5 Nm |
| 10/12 Kw | 1/0 AWG | 50 | 24.5 Nm |
Please follow the below steps to implement battery connection:
- Please choose a suitable battery cable with the correct connector which can well fit into the battery terminals.
- Use a suitable screwdriver to unscrew the bolts and fit the battery connectors in, then fasten the bolt by the screwdriver, making sure the bolts are tightened with a torque of 24.5 N.M in a clockwise direction.
- Make sure the polarity at both the battery and inverter is correctly connected.
- In case of children touch or insects go into the inverter, Please make sure the inverter connector is fastened to a waterproof position by twisting it clockwise.

3.4 Grid connection and backup load connection
- Before connecting to the grid, please install a separate AC breaker between the inverter and the grid. Also, it is recommended that installs an AC breaker between the backup load and inverter. This will ensure the inverter can be securely disconnected during maintenance and fully protected from overcurrent. The recommended of AC breaker for the load port is 20A for 8kw, 32A for 10kw, and 32A for 12KW. The recommended of AC breaker for the grid port is 63A for 8kw, 63A for 10kw, and 63A for 12KW.
- There are three terminal blocks with “Grid” “Load” and “GEN” markings. Please do not misconnect in ut and output connectors.
| Model | Wire Size | Cablel (mm2) | Torque value (max) |
|---|---|---|---|
| 5/6/8/12 Kw | 10 AWG | 4 | 1.2 Nm |
| Model | Wire Size | Cablel (mm2) | Torque value (max) |
|---|---|---|---|
| 5/6/8/12 Kw | 10 AWG | 6 | 1.2 Nm |
Please follow the below steps to implement Grid, load and Gen port connection:
- Before making the Grid, load and Gen port connection, be sure to turn off the AC breaker or disconnector first.
- Remove the insulation sleeve 10 mm in length, unscrew the bolts, insert the wires according to the polarities indicated on the terminal block, and tighten the terminal screws. Make sure the connection is complete.
- Then, insert AC output wires according to the polarities indicated on the terminal block and tighten the terminal. Be sure to connect corresponding N wires and PE wires to related terminals as well.
- Make sure the wires are securely connected.
- Appliances such as air conditioner are required at least 2-3 minutes to restart because it is
- required to have enough time to balance refrigerant gas inside the circuit. If a power shortage occurs and recovers in a short time, it will cause damage to your connected appliances. To prevent this kind of damage, please check with the manufacturer of the air conditioner if it is equipped with a time-delay function before installation. Otherwise, this inverter will trigger an overload fault and cut off output to protect your appliance but sometimes it still causes internal damage to the air conditioner.
3.5 PV Connection
