4 Wiring Diagram

Wiring diagrams are provided for different regions, including Australia, New Zealand, and South Africa, and for other countries. It is essential to follow local wiring regulations.

Model Specifications

The following table details the recommended DC breaker, AC breaker, and RCD ratings for each inverter model.

Notes:

• If the battery has an integrated DC breaker, no additional ① DC breaker is required.
• The use of ⑥⑦ 30mA RCD is recommended but not mandatory; please comply with local regulations for system installation.

5 Electrical Connection

Step 1 Grounding Protection Wire

Connect the grounding wire (S≥6mm²) to the inverter's ground terminal using an M4 screw (1.2 N·m). Ensure proper wire stripping (7-8mm and 20-25mm).

Step 2 Grid Connection (Same wirings for GEN connector, leave it alone if not used)

Connect the Grid or Generator connector using MC4 connectors. Ensure proper wire stripping (13mm-18mm) and torque (M6, 2 N·m).

Step 3 EPS Connection

Connect the EPS connector using appropriate terminals and torque.

Step 4 PV Connection

Connect PV+ and PV- MC4 connectors to the inverter. Use wires with a diameter of 4-5mm and a cross-sectional area between 2.5mm² and 4mm².

Step 5 Battery Connection

Connect Battery+ and Battery- connectors to the inverter. Use wires with a cross-sectional area of 20-25mm².

6 Signal Communication

RJ45 Terminal Connection (METER, BMS)

Connect METER and BMS devices to the inverter using RJ45 cables, following the port assignments shown in the diagrams.

Step 7 Data Transfer Stick (DTS)

Wi-Fi Connection:

Mount the DTS, connect the antenna, and establish a Wi-Fi connection.

Ethernet Connection:

Connect an Ethernet cable to the DTS for network communication.

Signal Communication Pinout

A table details the function of various terminals including Meter (RS485), BMS (CAN, RS485, NTC), DRM, DI (Dry-contact input), Parallel operation terminals, 120 Ohm termination resistor, and DO1/DO2 (Dry-contact output) for control functions like Earth Fault Alarm, Load Control, etc.
