Warning

1. Disconnect any electrical connection and verify no live voltage before installation to prevent potential electrical hazards.
2. Verify Inverter AC Switch is in the “OFF” position.
3. Verify equipment has adequate ventilation to ensure system performance.
4. Ensure the area of operation has no strong electromagnetic sources nearby.
5. Please ensure there is no heat source nearby.
6. Before doing any maintenance work, please ensure the power is off.
   Note: All operations must be conducted by professional electrical technicians

 Installation

1. Use the 4 M4 x 10 cross screws to fix unit to the wall.
2. Torque value = 1.2Nm

Cable Connection

1. Strip off the insulation as shown below.
2. Use a slot-type screwdriver to press the position in red and insert the A, B, C to Pin 1,2,3.

3. Connect the terminal to PLC CCO as shown below.
4. Connect RS485 communication cable to COM1(RJ45) or COM2(4 core connector)

5. Connect 12V power line to PWR DC 12V port on the PLC CCO device.

Working Principle

Solis string inverters integrated with PLC communication module “PLC STA”” can conduct PLC through AC power cables and communicate with the PLC CCO. The PLC CCO uses the isolation coupling circuit to isolate low-frequency AC power and protects the internal board. It conducts bi-directional PLC signaling and RS485 signal conversion to communicate with a corresponding data logger.
The diagram of the PLC communication system is as follows:

Characteristic

1. Adopt OFDM technology, subcarrier supports BPSK, QPSK, 8QAM, 16QAM, 64QAM modulation method.
2. Integrated with a high-performance ARM CPU, the main frequency reaches 266MHz, satisfying smart grid requirements.
3. Support FEC and CRC function with strong capability of noise reduction and error recovering.
4. Support ad-hoc network and dynamic-route addressing function.
