Fronius Inverter STATE 567 Error: Meaning, Causes & Safe Fix

STATE 567 is informational: Grid Voltage Dependent Power Reduction (volt-watt mode) is active — the inverter is deliberately reducing output because grid voltage is high.

What should I do first?

Two quick questions — we'll point you to the right starting point.

Is this code still showing on your inverter's display?

What this code means

STATE 567 tells you the inverter's Grid Voltage Dependent Power Reduction (GVDPR, or volt-watt mode) has activated. When grid voltage climbs too high (above about 250V AC), the inverter reduces its power output to help bring local voltage down — this is normal, standards-compliant behaviour. The inverter keeps operating, just at reduced power. Acknowledge the message on the display.

Common causes

Elevated grid voltage during high solar export periods
Local network voltage running near the upper limit
Voltage rise from your own system exporting
Network conditions in your area

Safe steps to try

Work top to bottom, ticking off each step as you complete it. 0 of 5 done.

Acknowledge the code on the display (press Enter)
No action is needed — this is normal protective behaviour
Monitor whether it happens very frequently
Note any pattern, such as time of day or sunny days
If it keeps recurring and generation is noticeably affected, contact your installer

Is your inverter still under warranty?

Before paying for a repair, check — your installer may fix this free.

Brand Year installed

Based on typical standard warranty terms — always confirm with your warranty card or installer paperwork, as terms vary by model, region, and purchase date.

When to call an electrician

Contact your solar installer if STATE 567 keeps recurring and is significantly reducing your generation — they can review volt-watt settings and arrange a network voltage assessment. Never change grid-code settings yourself.

Frequently asked questions

Is STATE 567 a fault?

No — it is the inverter working exactly as designed, reducing output to manage high grid voltage. It clears automatically.

Why is my output lower when 567 shows?

That is the point of volt-watt mode: lower output means less voltage rise on the grid. Output returns to normal as voltage drops.

Can I turn off volt-watt mode?

No — it is required by grid standards and must stay enabled. If it is hurting your generation, your installer and network operator are the right people to talk to.
