Mounting Instructions

Installation Precaution
This Hybrid inverter is designed for outdoor use(IP65), 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%).

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 to allow touch screen display to be read at all times.
• The ambient temperature should be between -25~60°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.

1. Please Make sure that the thickness of the wall for inverter installation is more than 70mm.
2. Please Place the bitmap horizontally on the wall and confirm the level by level.
3. Please mark the holes in the 4 mounting holes of hole pattern.
4. Drill a hole with a depth of 65mm at the mark with a drill of 10mm.
5. Please knock the expansion screw rubber sleeve into the hole on the wall, and then screw on the Expansion screw.
6. Please hang the inverter on the expansion screws, and then tighten the expansion screws.

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.

Attention: All wiring must be performed by a professional person. Connecting the battery with a suitable cable is important for the safe and efficient operation of the system. To reduce the risk of injury, refer to the chart for recommended cables.

Please follow the below steps to implement battery connection:

1. Please choose a suitable battery cable with the correct connector that can well fit into the battery terminals.
2. Use a suitable screwdriver to unscrew the bolts and fit the battery connectors in, then fasten the bolt with the screwdriver, making sure the bolts are tightened in a clockwise direction.
3. Make sure the polarity at both the battery and inverter is correctly connected.

Temperature sensor connection for lead-acid battery

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 an AC breaker be 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 is 80A for 10kw. There are three terminal blocks with “Grid” “Load” and “GEN” markings. Please do not disconnect the input and output connectors.
• ATTENTION: All wiring must be performed by qualified personnel. System safety and efficient operation need to use appropriate cable for AC input connection. To reduce the risk of injury, please use the proper recommended cable as below.

Please follow the below steps to implement an AC input/output connection:

1. Before making the Grid, load and Gen port connection, be sure to turn off the AC breaker first.
2. Remove insulation sleeve 10 mm for positive and negative conductors.
3. Use crimping pliers to press the 6AWG cable onto the attached tubular terminal to form a quadrilateral.
4. Install the AC conduit to the AC grid output opening (Grid, Gen, Load). Use appropriate conduit fittings and bonds where necessary.
5. Terminate the AC conductors to the appropriate terminal.

Attention
Be sure that the AC power source is disconnected before attempting to wire it to the unit. Appliances such as air conditioners require at least 2-3 minutes to restart because it is required to have enough time to balance refrigerant gas inside of the circuit. If a power shortage occurs and recovers in short time, it will cause damage to your connected appliances. To prevent this kind of damage, please check 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.

PV Connection

• Before connecting to PV modules, please install a separate DC circuit breaker between the inverter and PV modules.
• System safety and efficient operation need to use appropriate cable for PV module connection.
• To reduce the risk of injury, please use the proper recommended cable size as below.

Attention

• To avoid any malfunction, do not connect any PV modules with possible current leakage to the inverter.
• For example, grounded PV modules will cause current leakage to the inverter.
• When using PV modules, please be sure NO grounding. It is requested to use a PV junction box with surge protection.
• Otherwise, it will cause damage to the inverter when lightning occurs on PV modules.

PV Module Selection
When selecting proper PV modules, please be sure to consider below parameters:

1. The open circuit Voltage (Voc) of PV modules does not exceed the max PV array open circuit voltage of the inverter.
2. Open circuit Voltage (Voc) of PV modules should be higher than the minimum start voltage.

PV Module Wire Connection
Please follow the below steps to implement the PV module connection:

1. Remove insulation sleeve 10 mm for positive and negative conductors.
2. Use crimping pliers to press the 10AWG cable onto the attached tubular terminal to form a Quadrilateral.
3. Check the correct polarity of the wire connection from PV modules and PV input connectors. Then, connect the positive pole (+) of the connection wire to the positive pole (+) of the PV input connector. Connect the negative pole (-) of the connection wire to the negative pole (-) of the PV input connector. Close the switch and make sure the wires are tightly fixed.
4. Parallel strings per MPPT must be the same Voltage.
   • a. PV1 A/B must be the same voltage if using both strings.
   • b. Panels of the same MPPT can be installed in the same orientation, while panels of different MPPTs can be installed in different orientations.
5. Terminate the PV strings to the appropriate terminal.
   • Attention: Make sure the wire is compacted.

Rapid Shutdown
The inverter includes a rapid shutdown system that complies with 2017 and 2020 NEC 690.12 requirements. In case of emergency, press the rapid shutdown button that cuts off the RSD power supply, thus stopping the inverter AC output, and the PV conductor voltage will be reduced to less than 30V within 30 seconds.

1. Mounting the RSD initiation switch
   • a. Using a Philips head screwdriver, unscrew the 4 plastic screws of the assembled RSD initiation switch to open the enclosure.
   • b. Use the base of the enclosure to mark 4 holes on the wall and drill the holes out. Insert the wall anchors into the holes.
   • c. Align the holes of the RSD initiation switch base with the holes in the wall. Using a Philips screwdriver, screw the self-tapping screws through the enclosure base into the wall anchors.
2. Wiring the RSD initiation switch
   • a. Install RSD switch wire to the COM input, use appropriate conduit fittings and bond where necessary. Run the signal wire.
   • b. Connect the wire to the RSD switch as shown.
   • c. Reinstall the RSD initiation switch cover and tighten the plastic screws to secure.
   • d. Remove the 3-pin connector from terminal CN17 and remove the jumper across the pins.
   • e. Insert the wire in the 3-pin conductor’s positions 1 and 3, as shown.
   • f. Replace the connector in the terminal CN17 and replace the inverter wire box cover.
