What should I do when my hybrid inverter shows an error code in South Africa?

Photograph the code and the LED state, check the local display before blaming the app, then match the code to the OEM manual — many “faults” are grid-loss, isolation, or CT polarity issues that a registered installer must clear.

Updated 27 October 2026 · Illustrative ranges — not a formal quote, credit decision or legal advice.

Answer first: Do not factory-reset until you have photos and the firmware version. Check whether the house is islanding correctly, then open the OEM error list — monitoring · firmware · earth leakage · DC isolation · warranty claim.

First five minutes

Photo the code, timestamp, and LED pattern.
Note Stage status and whether essentials are live.
Check breakers/isolators before pressing reset repeatedly.
Message the installer with photos — not only a WhatsApp “it’s broken.”

Error-code triage before the call-out fee

Screenshot the exact code, LED pattern and portal event time. Check AC/DC isolators, RCD status and whether the grid was in a Stage. Many faults clear after a controlled reboot per OEM — but repeated isolation or ground-fault codes are stop-work. Keep the CoC and serial numbers ready for warranty.

Never reset breaker trips that smell of burning.
Export CSVs before a technician clears logs.
Match firmware version to the code list in the manual — when to call · firmware · warranty claim.

Quick questions

App offline but display OK?

Connectivity issue — production may still be fine.

Grid-loss during Stage?

Often normal island transition — confirm essentials stayed up.

Isolation / earth fault?

Power down safely and call the installer — do not reset forever.

Warranty?
