When to call your installer or the warranty line

Your installer is your first warranty contact. If they've gone, the manufacturer's warranty line still covers the hardware. Don't open the inverter or battery case yourself: work inside it is for a licensed electrician.

If you see smoke, scorch marks or smell burning, switch the system off at the AC and PV isolators and call your installer. If anyone is in danger, call 000.

  1. Try the free fixes first

    Most faults are an isolator, a WiFi drop or a known error code. Start with the lookup and guides above.

  2. Then call the people who are responsible for it

    Your installer is your first warranty contact. If they've gone, the manufacturer's warranty line still covers the hardware.

  3. If it's near the end of its life, see what replacing it would do

    A free energy audit report sizes a new system for your actual bills and shows what a replacement would do. Your first results need no details; your details only reach installers if you ask for the full report.
