4.1 Preparation

Before connecting any wiring, take off the bottom cover by removing two screws. Ensure all safety precautions are followed.

4.2 Mounting the Unit

Consider the following points when selecting where to install the inverter:

• Do not mount the inverter on flammable construction materials.
• Mount on a solid surface.
• Install this inverter at eye level to allow the LCD display to be read at all times.
• For proper air circulation to dissipate heat, allow a clearance of approximately 20 cm to the side and approximately 50 cm above and below the unit.
• The ambient temperature should be between 0°C and 55°C to ensure optimal operation.
• The recommended installation position is to be adhered to the wall vertically.
• Be sure to keep other objects and surfaces as shown in the diagram to guarantee sufficient heat dissipation and to have enough space for removing wires.

4.3 Battery Connection

Please follow the steps below to implement 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. Connect all battery packs as shown in the chart below.

4.4 PV Connection

CAUTION: Before connecting to PV modules, please install separately a DC circuit breaker between the inverter and PV modules. This is crucial for safety and system protection.

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

Image: Comprehensive connection diagram illustrating how PV panels, utility grid, generator, battery, and home appliances connect to the hybrid solar inverter. Below the diagram, a table provides recommended cable sizes and torque specifications for different inverter models (1.5KVA, 3.5KVA, 5.5KVA) to ensure safe and efficient operation.

When selecting proper PV modules, please consider the following parameters:

• Open circuit voltage (Voc) of PV modules must not exceed the maximum PV array open circuit voltage of the inverter (500VDC for 5.5KVA).
• Open circuit voltage (Voc) of PV modules should be higher than the minimum battery voltage.

Image: This image shows the product display along with guidelines for PV module selection, including maximum PV array open circuit voltage and MPPT voltage range. A table provides an example of solar panel configuration (e.g., 330Wp modules) for different inverter models, detailing the quantity of panels in series and parallel to achieve the required total input power.

Example: For a 330Wp PV module, recommended module configurations are listed in the table below:

4.5 AC Connection
