Share the installer, panel and inverter models, installation date, error messages, and when the fault occurs. Ask whether the provider supports your system brand and whether they need to inspect it before quoting. Do not assume a warranty transfers to a different repairer; check the manufacturer’s and installer’s terms first.
Ask for a diagnosis, parts estimate, and explanation of any effect on existing warranties. Browse service businesses on KobStore and confirm system experience and warranty implications before authorising repairs.
