Observe safely before requesting service
Record the exact model, serial number, timestamp, fault code and symptoms using safe access to the normal display or app. Note weather, grid interruptions and recent work. Do not open enclosures, climb onto a roof, repeatedly reset a fault or operate unfamiliar isolators. Keep away from smoke, heat, damaged cables or battery swelling; contact emergency services on 112 for immediate danger.
Distinguish measured voltage and inverter events
Log the event, time, operating power and relevant voltage measurements using the approved procedure. An electrician should assess the installation's cable route, connections, protection, phase arrangement and voltage rise during export. Distinguish an installation issue from a supply issue and submit evidence to the relevant distributor when appropriate.
Do not bypass grid protection
Grid settings and protective thresholds must follow the approved configuration and applicable connection rules. Do not raise trip limits, bypass protection or repeatedly reset equipment to force generation. Establish the cause and the permitted corrective work with qualified personnel before changing settings.
Size storage for a defined purpose
Separate usable energy in kWh from continuous and starting power in kW. Check reserve, efficiency, permitted discharge, temperature limits and exact inverter/firmware compatibility. A battery shifts energy with losses; it does not create free electricity. Compare a no-storage scenario before assigning any financial benefit to additional capacity.
Backup is a separate design
Ordinary grid-tied generation stops when the grid fails. Backup requires a supported operating mode, isolation from the grid, an approved earthing and protection arrangement, and defined circuits and loads. Check transfer behaviour and starting power against equipment requirements. A hybrid label or battery connection alone does not guarantee uninterrupted whole-home operation.
Diagnose the installation, not a brand stereotype
A qualified professional should distinguish supply faults, PV-string conditions, communications, siting, settings, firmware and hardware using the exact manufacturer's diagnostic procedure. A fault code or an online complaint does not establish a product-wide defect or failure rate. Record tests and the basis for a proposed repair before ordering replacement parts.
Keep a commissioning record
Agree the inspections, measurements, settings and documents applicable to the installation. Retain equipment identification, as-built diagrams, protection details, test results, operating instructions and handover records. Monitoring access is useful, but an app displaying generation is not proof of electrical safety, completed registration or an active export-compensation contract.
