Deye Inverter WiFi and Solarman Logger Setup Guide

Key Takeaways

• Deye inverters require an optional WiFi Plug or datalogger for remote monitoring via platforms like Solarman.
• The WiFi Plug connects to a dedicated WiFi Interface port, while a datalogger uses the RS232 port.
• Configuration details for the WiFi Plug are typically found in its own accessory manual.
• Always ensure all connections are secure and follow safety guidelines when installing or troubleshooting.

How do I set up WiFi monitoring for my Deye inverter with Solarman?

Deye inverters use an optional WiFi Plug or a datalogger to connect to monitoring platforms like Solarman. The WiFi Plug connects to a dedicated WiFi Interface port, while a datalogger connects via the RS232 port. These accessories enable remote system access and performance tracking.

Diagnosis

If your Deye inverter is not communicating with the Solarman app or showing data, follow these steps to diagnose the connection.

1. Verify WiFi Plug Installation:

• • Check: Locate the dedicated WiFi Interface port on your Deye inverter. For SG03LP1 and SG01LP1 series, this is labeled "19". For SG04LP1 series, it is labeled "18". Confirm that the optional WiFi Plug is securely inserted into this port.
  • Meaning: If the plug is missing or loose, the inverter cannot establish a WiFi connection. The WiFi Plug is an optional accessory and is not a standard configuration.

2. Inspect Datalogger Connection (if applicable):

• • Check: If you are using a separate WiFi datalogger, ensure it is connected to the inverter's RS232 port.
  • Meaning: An improperly connected datalogger will prevent data transmission. The RS232 port is specifically used to connect the WiFi datalogger.

3. Review WiFi Plug Configuration:

• • Check: Refer to the specific illustrations and instructions provided with your WiFi Plug accessory.
  • Meaning: The configuration process for the WiFi Plug is detailed in its own manual, not the inverter manual. Incorrect settings on the plug itself will prevent communication.

4. Confirm RS232 Pinout:

• • Check: If using an RS232 datalogger, verify the pinout for the RS232 port. The pin definitions are: Pin 1: D-GND, Pin 5: TX, Pin 6: RX, Pin 7: 12Vdc.
  • Meaning: Incorrect wiring of the RS232 cable can lead to communication failures.

5. **Identify Logger Interface Type (for SG01LP1, SG04LP1 models):

• • Check: Some Deye inverter models, specifically SG01LP1 and SG04LP1, have two types of logger interfaces: DB9 and USB. Visually confirm which type is present on your inverter.
  • Meaning: Using the wrong type of datalogger or cable for the available interface will prevent connection.

Deye Inverter WiFi and Datalogger Interfaces

Deye hybrid inverters are designed with connectivity in mind, but remote monitoring capabilities like those offered by Solarman require additional hardware. Your inverter will have a dedicated port for this purpose, but the monitoring device itself is an optional accessory.

There are generally two ways to enable remote monitoring:

1. WiFi Plug: This is a compact accessory that plugs directly into a dedicated WiFi Interface port on the inverter. For Deye SG03LP1 and SG01LP1 series inverters, this port is labeled "19". On SG04LP1 series inverters, it is labeled "18". The configuration of this WiFi Plug is typically covered in its own separate manual, which provides specific illustrations and setup steps. The WiFi Plug is listed as an optional accessory in the parts list.
2. WiFi Datalogger via RS232: Alternatively, a WiFi datalogger can be connected to the inverter's RS232 port. This port is specifically used to connect the WiFi datalogger. The RS232 port has a defined pinout: Pin 1: D-GND, Pin 5: TX, Pin 6: RX, Pin 7: 12Vdc. Some models, such as the SG01LP1 and SG04LP1, may have different logger interfaces, including DB9 and USB types. It is important to check your specific inverter model to identify the correct logger interface.

Safety: Working with Inverter Connections

Always prioritize safety when working with your Deye inverter. Disconnect all power sources before making or checking any connections.

• Electrical Shock Risk: To reduce the risk of electric shock, disconnect all wires before attempting any maintenance or cleaning. Turning off the unit will not reduce this risk.
• Wiring by Professionals: All wiring must be performed by a professional person.
• Disconnect Power: Be sure that the AC power source is disconnected before attempting to wire it to the unit.
• Grounding: The inverter should be connected to a permanent grounded wiring system, complying with local requirements. The ground cable shall be connected to the ground plate on the grid side to prevent electric shock.
• No Short Circuits: Never cause AC output and DC input to be short-circuited. Do not connect to the mains when DC input is short-circuited.

When to call a technician instead

If you have followed all the troubleshooting steps and your Deye inverter still does not communicate with the Solarman platform, or if you are unsure about any wiring or configuration steps, it is best to contact a qualified technician. The manufacturer, Ningbo Deye Inverter Technology Co., Ltd., advises contacting your local dealer or service center if fault messages persist after restarting. Provide them with your inverter's serial number, distributor information, on-grid power generation date, a detailed problem description (including any fault codes or indicator statuses), and your contact information. Attempting repairs or modifications without proper training can void your warranty and pose significant safety risks.
