INSTALLATION

Unpacking and Inspection

Before installation, please inspect the unit. Be sure that nothing inside the package is damaged. You should have received the following items inside the package:

1. The unit x 1
2. User manual x 1
3. Communication cable x 1
4. Software CD x 1

Preparation

Before connecting all wirings, please take off the cover of the bottom by removing the two screws as shown below.

Mounting the Unit

Consider the following points before selecting where to install:

• Do not mount the inverter on any flammable construction materials.
• Mount this inverter on a solid surface
• Install this inverter at eye level in order to read the LCD display at all times.
• The ambient temperature should be between 0°C and 55°C to ensure optimal operation.
• The inverter should be adhered to the wall vertically.  Be sure to keep other objects away and leave the space in a minimum as shown in the right diagram to guarantee sufficient heat dissipation and enough space for replacing wires.

NOTES: SUITABLE FOR MOUNTING ON CONCRETE OR OTHER NON-COMBUSTIBLE SURFACE ONLY.

Install the unit by screwing two screws as shown in the diagram. It’s recommended to use M4 or M5 screws.

Battery Connection

CAUTION: For safety operation and regulation compliance, it’s requested to install a separate DC over-current protector or disconnect the device between battery and inverter. It may not be necessary to disconnect the device for some applications, however, it’s requested to have over-current protection installed. Please refer to the typical amperage in the table below as required fuse or size of the breaker.

WARNING! All wiring must be performed by a qualified personnel.

WARNING! It's very important for system safety and efficient operation to use appropriate cable for battery connection. To reduce risk of injury, please use proper cables and suitable size of terminal recommended below.

Recommended battery cables and size of terminal:

Please follow the steps below to implement the battery connection:

1. Remove insulation sleeve 18 mm for positive and negative conductors.
2. Suggest to put bootlace ferrules on the end of positive and negative wires with a proper crimping tool.
3. Fix strain relief plate to the inverter by supplied screws as shown in below chart.

Connect all battery packs as below chart.

Insert the battery wires flatly into battery connectors of inverter and make sure the bolts are tightened with torque of 2 Nm in clockwise direction. Make sure polarity at both the battery and the inverter/charge is correctly connected and conductors are tightly screwed into the battery terminals. Recommended tool: #2 Pozi Screwdriver

To firmly secure wire connection, you may fix the wires to strain relief with cable tie.

AC Input/Output Connection

CAUTION!! Before connecting to AC input power source, please install a separate AC breaker between inverter and AC input power source. This will ensure the inverter can be securely disconnected during maintenance and fully protected from over current of AC input. The recommended spec of AC breaker is 40A for 3KVA.

CAUTION!! There are two terminal blocks with “IN” and “OUT” markings. Please do NOT mis-connect input and output connectors.

WARNING! All wiring must be performed by the qualified personnel.

WARNING! It's very important for system safety and efficient operation to use appropriate cable for AC input connection. To reduce risk of injury, please use the recommended cable size as below.

Suggested cable requirement for AC wires

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

1. Before making AC input/output connection, be sure to open DC protector or disconnector first.
2. Remove insulation sleeve 10mm from the six conductors. And short-circuit phase L and neutral conductor N 3 mm.
3. Insert AC input wires according to polarities indicated on terminal block and tighten the terminal screws. Be sure to connect PE protective conductor first.
   

Then, insert AC output wires according to polarities indicated on terminal block and fasten the terminal screws. Be sure to connect PE protective conductor first.

Make sure the wires are securely connected.

PV Connection

CAUTION: Before connecting to PV modules, please install separately a DC circuit breaker betwand PV modules.

WARNING! All wiring must be performed by a qualified personnel.WARNING! It's very important for system safety and efficient operation to use appropriate module connection. To reduce risk of injury, please use the recommended cable size as below.

PV Module Selection:

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

1. Open circuit Voltage (Voc) of PV modules can’t exceed the maximum voltage of the PV array open circuit of the inverter.
2. Open circuit Voltage (Voc) of PV modules should be higher than the minimum voltage of the battery.

Please follow the steps below to implement PV module connection:

1. Remove insulation sleeve 10 mm from positive and negative conductors.
2. Check the correct polarity of connected cable from PV modules and PV input connectors. Then, connect positive pole (+) of connection cable to positive pole (+) of PV input connector. Connect negative pole (-) of connection cable to negative pole (-) of PV input connector.
   
3. Make sure the wires are securely connected.

Final Assembly

After connecting all wirings, please put the bottom cover back by fixing two screws as shown below.
