Connection Error Codes and Their Solutions

If an error occurs when activating the dynamic power control on the Trydan or Trydan Pro charger, a code corresponding to the error will appear on the charger’s display.

The solutions to the errors listed below apply to version 1.6.18 or higher. If you are using a version below this, please update Trydan and check the following list again.

IMPORTANT NOTE: These errors arise from a communication failure between Trydan and the inverter or meter, limiting the charging of your vehicle to the minimum. Some may occur when integration is direct with the inverter, either through Modbus or RS485 communication.

It is essential to refer to the solution for the error displayed. If the error persists, please report it to our Technical Support department and disable dynamic load control to enable charging at the established fixed current.

ERROR 00 000
A
B

The first two digits indicate the meter or inverter being used. It is crucial to select the appropriate one when configuring dynamic power control and to verify that it is correct in the event of an error.

Errors – B

001 For Goodwe equipment with UDP protocol
Check:
– Both the inverter and charger are connected to the internet.
– The IP of the inverter is incorrectly assigned in the e-Charger.

002 For V2C Meter 1.0 and 2.0: frames are arriving corrupted.
Check:
– Correct crimping of the RJ-45 connector at both ends.
– Correct configuration of dynamic control with the selected meter corresponding to the installation.

003 Possible noise in the V2C ControlBox signal.
Check:
– CCorrect crimping of the RJ-45 connector at both ends.
– Correct configuration of dynamic control with the selected meter corresponding to the installation.

004 Trydan is disconnected from WiFi and attempting to reconnect, and the WiFi meter uses that WiFi technology to connect.
Check:
– Correct connection of both devices to the same customer WiFi (not to the charger).
– Ensure that the signal strength is optimal or improve it using a repeater for the WiFi connection to which both are connected.

005 The V2C ControlBox connected via RJ-45 is unresponsive.
Check:
– Correct crimping of the RJ-45 connector at both ends.

006 An HTTP request has failed to connect (Shelly, Solax, Kostal Piko, Enphase, P1 Meter, SAJ [Solar Data], Wibeee). Fails when attempting to connect to the Modbus TCP server (Huawei, Kostal Plenticore, Fronius, Ingeteam, SMA Sunny, SolarEdge, Victron).
Check:
– Correct connection of both devices to the same customer WiFi (not to the charger).
– Ensure that the signal strength is optimal or improve it using a repeater for the WiFi connection to which both are connected.
– Correct configuration of the inverter concerning the communication parameters with Trydan.

007 The automatic search for Shelly found no devices.
Check:
– Change to a fixed IP for the Shelly in the Trydan charger.
– Correct connection of both devices to the same customer WiFi (not to the charger).

008 A meter with WiFi technology has been selected, and Trydan has never connected to the configured WiFi network.
Check:
– Correct connection of both devices to the same customer WiFi with sufficient signal (not to the charger).

009 A Timeout is received from the meter request.
Check:
– Correct crimping of the RJ-45 connector at both ends.
– Correct configuration of the inverter concerning the communication parameters with Trydan.
– In the case of a WiFi inverter or meter, the correct connection of both devices to the same customer WiFi with sufficient signal (not to the charger).
– The IP of the inverter must be correctly configured in the dynamic power control of Trydan.
– Solax inverter: Correct version of the Pocket WiFi V2.033.20 (download link included in the manual).

010 A message is received indicating a clamp not connected on a channel that is necessary (Mono + FV clamp 1 or 4, Three-phase clamps 1, 2 or 3).
Check:
– Correct placement of the clamps on the phases indicated in the correct installation diagram for each case.

IMPORTANT NOTE: If the error code is greater than 011, these are errors classified in the MODBUS RTU or TCP protocol. For specialist personnel only. You can generate a request in the Technical Support Centre, and we will contact you as soon as possible.
