Solar & Backup Power / Cape Town

Service assessment and practical solutions

Check whether production stopped or only the app went offline

A blank graph does not always mean that the panels have stopped producing electricity. Inverters can operate locally while their wireless logger, router or cloud connection fails. We ask what the inverter screen shows, whether lights and appliances still receive expected power, and when the app last reported data. Those observations separate a communications problem from a generating or battery fault. Do not change protection settings or open electrical compartments just because the phone displays an alarm.

Trace the communications path

Many installations rely on a Wi-Fi or Ethernet data logger and a manufacturer cloud service. A changed router password, weak signal, disabled internet service or replaced phone can interrupt the display. Other systems use a cellular logger or a local gateway. We identify the inverter and logger model, supported network type and account ownership before trying to reconnect anything. The goal is to restore visibility without resetting energy settings, deleting historical data or linking the equipment to the wrong owner account.

Protect account access and site credentials

System monitoring apps can expose consumption data and sometimes remote control functions. Homeowners should use the manufacturer’s account recovery and installer-transfer process, not share passwords in public messages. We discuss whether the previous installer controls the portal and whether the owner has the necessary serial numbers. A legitimate handover should leave the correct party with access and provide a record of what settings were changed. A device with defective hardware may need a suitable replacement logger.

Verify actual data after reconnection

Once connectivity is restored, the app should be checked against the inverter’s own display for sensible generation, grid import and battery readings. A communications repair cannot by itself promise improved panel output. If the restored graphs reveal abnormal energy performance, that becomes a separate diagnostic scope. Cape Town PV compliance remains relevant to any changes involving electrical operation, but a straightforward app reconnection should not be presented as a new municipal authorisation.

Recognise the situation

Common enquiries and what changes the job

Router was replaced and app stopped updating

The logger may still be tied to the previous Wi-Fi details.

Homeowner bought a house with solar

Portal ownership and previous installer access should be resolved safely rather than creating duplicate device registrations.

Inverter works but graph is flat

Compare local output readings with the online portal before assuming the PV array failed.

Before booking

Information that helps define the work

Provide the inverter brand, data logger model, app name and a screenshot of the error with private details obscured.

Tell us whether the router or ownership recently changed and whether the inverter still displays normal local generation and battery status.

Where applicable in the City of Cape Town electricity supply area, new solar PV/battery systems and relevant system changes must follow the City authorisation process. Professional sign-off and suitable approved inverters are important requirements; never activate an unauthorised modified system.

Frequently asked questions

Solar Monitoring Wi-Fi & Portal Reconnection: customer questions

Can lost Wi-Fi make the solar panels stop generating?

Often only monitoring is affected, but system-specific controls differ. Local inverter readings help distinguish the two.

Do you need my app password?

Sensitive credentials should not be sent by ordinary text or published in a booking form. Use secure manufacturer procedures.

Will reconnecting the app increase solar output?

Not by itself. It restores visibility; performance problems require separate investigation.
