1. Why isn’t my Eco 22 kW charger charging at full speed?

• To achieve the full 22 kW output, the charger must be connected to a three-phase AC supply, and the vehicle must support 22 kW AC charging.
• If charging is limited to 7.4 kW or 11 kW, it is usually because the EV does not support 22 kW, the site has only single-phase or partial three-phase power, load balancing is active, or the charging cable is rated for lower current, which causes the charger to safely limit power.

2. My charger shows a solid or flashing red LED — what does this indicate?

• A red LED signals a critical fault condition
• This may be caused by grid issues such as over- or under-voltage, frequency problems, DC leakage, or internal conditions like overheating.
• Restart the charger by switching the incoming MCB OFF and ON. If the red LED remains, connect the charger online and contact technical support.

3. Charging starts but stops after a few seconds — why does this happen?

• This usually occurs when charging conditions are not met or a control setting interrupts the session.
• Check that scheduled charging is disabled in both the app and the vehicle, confirm input voltage and earthing are within limits, and restart the charger.
• If the issue continues, contact technical support.

4. The charger will not connect to Wi-Fi or Ethernet — what should I do?

• Confirm the Wi-Fi signal is strong or the Ethernet cable is working.
• If DHCP fails, try using a static IP. Ensure your firewall allows charger communication ports
• Restart the router and charger, then connect the charger in AP Mode and reconfigure Wi-Fi settings.
• Contact technical support if the issue persists.

5. Why is my EV not locking into the charging connector?

• The locking pin may be stuck or misaligned.
• Check the connector for dust or debris and clean if needed.

26. Can I lock the Eco 22 kW charger to prevent public or unauthorised use?

• Yes. Access can be restricted using RFID cards or fobs, mobile app authentication, or scheduled access rules through the backend system.
• Your installer or system administrator can configure these options.

27. The LED is solid green, but my EV is not charging — why?

• A solid green LED means the charger is powered and ready.
• Charging may not start if the EV battery is already full, a delayed charging schedule is active, or the connector is not fully inserted.
• Unplug and reconnect firmly, then check your EV’s charging settings.

28. How can I confirm that all three phases are working correctly?

• A qualified electrician can measure voltage between L1–L2, L2–L3, and L3–L1 using a multimeter; each should read around 400 V.
• Some chargers also display real-time phase current in the app or interface, helping confirm balanced three-phase supply.

29. Why does the charger draw power from only one phase?

• This can happen if the EV supports only single-phase charging, the charging cable is rated for single-phase use, or there is a phase rotation or wiring issue.
• Verify that both the EV and charger support three-phase charging and that wiring is correct.

30. Why does charging not stop immediately when I unplug the connector?

• Charging stops as soon as the connector is unplugged, and the connector unlocks automatically.
• There is no intentional delay.
• If the charger does not behave this way, the unit should be inspected by an authorised service provider.

31. The charger resets every few hours — is this normal?

• No, unless a scheduled reboot was configured.
• Frequent resets may indicate an internal safety watchdog reset, firmware instability, or another internal issue.
• Please contact technical support for diagnosis.

32. Can I manually limit the Eco 22 kW charger to 11 kW?

• Yes. The charging current can be limited by accessing the charger in AP mode and adjusting the current settings.
• In some cases, internal PCBA configuration is required.
• Any internal or hardware adjustments must be performed only by factory-authorised personnel to maintain safety and warranty.

33. Why is the OCPP server rejecting my charger registration?

• This often occurs if the charger ID is already registered, the OCPP version does not match the server (for example, 1.6J vs 2.0.1), or the server does not support the selected authorisation mode.
• Check with your charging network provider to resolve this.

34. Can the Eco 22 kW charger be restarted remotely?
