Prerequisites

• Sourceful Zap

• CAT6 FTP ethernet cable (one end will be stripped)

Compatible Models

Microinverters

• SUN-G3-EU-230 Series (300W to 2000W)

Hybrid Inverters

• SUN-5/6/8/10/12K-SG04LP3-EU

• SUN-12/14/16K-SG01LP1-EU

• SUN-5/6/8/10/12/15/20/25K-SG01HP3-EU

• SUN-(29.9-50)K-SG01HP3-EU

Wiring

Communication between the Sourceful Zap and Deye inverters uses Modbus RTU (RS485).

Strip one end of the ethernet cable. Use the green pair:

• Pin 1 (green/white) = 485_B

• Pin 2 (green) = 485_A

Zap Side

• Connect 485_A (green) to the Zap A+ terminal

• Connect 485_B (green/white) to the Zap B- terminal

Inverter Side

Plug the RJ45 end into the correct port for your model:

• SG04LP3-EU → port labeled Meter-485

• SG01LP1-EU → port labeled Modbus RS-485

• SG01HP3-EU → port labeled RS485

Do not use the BMS, Parallel, CAN, or DRM ports.

Inverter Setting

On the inverter display, navigate to:

Settings → Advanced Function → Paral. Set3

Set Modbus SN to 01.

Troubleshooting

If RS485 communication is not working:

1. Verify the Modbus SN is set to 01

2. Double-check you are using the correct port for your inverter model

3. Ensure all cable connections are firmly seated
