Koyoe error codes

Koyoe battery error code Grid Voltage Fault

Koyoe uses code Grid Voltage Fault in more than one product range, and it doesn't always mean the same thing. Check which range your battery belongs to below.

WattMate is not affiliated with Koyoe. This page summarises Koyoe's own published documentation; your installer and Koyoe are the authority on your system. WattMate doesn't repair systems or make site visits.

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.

We don't have a warranty line on file for Koyoe yet. See the manufacturer contacts we do hold, or ask your installer.

  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.
