SUN-5-12K-SG01HP3-EU-DM2 three-phase hybrid (F-series table)
Deye F06 error code
Control-board EEPROM write failure.
Likely causes
- Write-protected or corrupted EEPROM
- Firmware update interrupted while saving settings
- Control-board supply glitch or EMI
- Failed control board
Checks to run, in order
- 1Record the current settings and firmware version
- 2Power-cycle the inverter from DC and AC
- 3Re-check whether settings are retained after restart
Fixes
- Restart the inverter three times
- Restore factory settings and re-enter the site configuration
- Re-apply the correct firmware
When to escalate
If settings cannot be saved and F06 persists, the control board must be replaced by the distributor.
Fix it with the right tools
Check the system around the fault before replacing parts: load, battery bank, PV string and commissioning settings. If you need a second opinion, send the code and your inverter model to our team.
Before you open the inverter
- Isolate both the AC and DC sides, then confirm the display is dead before touching terminals.
- Use insulated tools and one hand where possible. DC arcs do not self-extinguish like AC.
- If you see burnt terminals, swollen cells, leaking electrolyte or a burning smell, stop and escalate instead of resetting the fault.
Questions installers ask
What does Deye F06 mean?
Control-board EEPROM write failure.
How do I fix Deye F06?
Restart the inverter three times Restore factory settings and re-enter the site configuration Re-apply the correct firmware
When should I escalate Deye F06?
If settings cannot be saved and F06 persists, the control board must be replaced by the distributor.
Can I reset Deye F06 myself?
Only after isolating the AC and DC sides and running the checks above. If Deye F06 returns immediately, stop resetting it and escalate; a repeating fault usually points to a real circuit, battery or hardware problem.
Which models show Deye F06?
Deye F06 is documented for SUN-5-12K-SG01HP3-EU-DM2 three-phase hybrid (F-series table). Confirm the code on your own unit's display or manual before ordering parts.
