Let’s get your monitoring connection back. An offline app alone does not tell you whether the system has stopped generating.
Before you begin
Use your phone, app and home router for these checks. Do not open covers, unplug modules, operate breakers or electrical isolators, restart the system or factory-reset equipment.
For a fault message, dead display or tripped breaker, use PSW Life Support. For smoke, burning smells, sparking, unusual heat or visible damage, keep clear and follow the safety advice.
Match the guide to your equipment
This route uses the owner section of the elekeeper V3 manual. Identify the communication module first. Older apps and different modules need matching instructions; do not uninstall an app or migrate accounts to force a match.
Have these ready
- Working home internet. Connect your phone to home Wi-Fi and open a webpage. If it will not load, resolve the home connection first.
- Your Wi-Fi details. Have the current network name and password ready. Enter passwords only in the manufacturer app or confirmed device interface, never in a PSW form or support message.
- Your usual account. Check you can sign in and see your system. Use account recovery if you cannot.
- A safe place nearby. Check the phone has a useful Wi-Fi signal near the equipment. Keep router security and system operating settings unchanged.
Reconnect one step at a time
- In elekeeper, open My → Remote Configuration with your owner account. Use a Bluetooth or Wi-Fi owner path only when it matches your module. Cloud access does not establish that the same Wi-Fi recovery path is available.
- For a compatible Bluetooth module, enable phone Bluetooth, select the matching device and open communication module → WiFi configuration. Leave inverter and battery settings alone.
- Use the matching module screen to select home Wi-Fi and enter its password. Compare section 7.7.5 (printed pages 39–41) before proceeding.
- If the module is not listed, the app offers only cloud configuration, or the screen differs, ask PSW for the exact module guide. The manual’s cloud-compatible series list does not establish that every SAJ inverter or EK70 / EK90 uses this same Wi-Fi procedure.
Check the app
Return your phone to its usual internet connection and reopen the app. Look for a connected status and check the time of the latest reading. Give the app time to apply the change before trying again.
A device connection and fresh cloud data are different checks. Neither, on its own, confirms generation or battery performance.
Still offline?
If the screen differs or setup fails, pause rather than repeat another model’s steps.
Send PSW Life Support the model, app, last-update time and the step you reached. A screenshot can help; hide private details and leave out passwords. Only photograph safely visible labels.
Different brand? Choose your equipment in the Wi-Fi assistant.
