Where do these Deye fault codes come from?

Compiled from publicly available Deye inverter and battery documentation and field references, then rewritten for the trade. Wattbench is independent and not affiliated with Deye.

Which of these can I clear on site?

Some clear on their own once grid or environmental conditions return to normal. Anything involving DC isolation, AC switching, wiring or opening the unit is licensed electrical work. Isolate safely, follow AS/NZS 5033 and AS/NZS 3000 procedure and use appropriate PPE before touching a live system.

The exact code isn't listed. Why not?

Firmware and model variants differ, and manufacturers revise their code tables. We document the most common ones; for a variant that isn't here, check the unit's current manual or the manufacturer's service portal.

About this fault librarySources · scope

The reviewed remedies in this library apply only where the official SUN-(5–12)K-SG04LP3-AU fault table carries the same F-code. Deye F-numbers are not stable across firmware, regional variants or rebadged hardware. F08 and F35 are retained only as deployed-firmware search aids because neither code appears in the reviewed Deye AU table; their remedies therefore remain blank even though secondary and community reports describe them. Sunsynk material is rebadge evidence, not primary Deye evidence. Confirm the exact model, region and firmware before acting. Safety note: owners should stop at recording visible app or display information. Isolation, configuration, testing, opening equipment and PV or battery cabling are licensed-electrician work and, where solar accreditation is required, work for an SAA-accredited person.

Key takeaways

23 Deye SUN-(5–12)K-SG04LP3-AU hybrid inverter and labelled deployed-firmware residues fault and alarm codes, documented for the trade.
Compiled from published documentation and field references; Wattbench is independent and not affiliated with Deye SUN-(5–12)K-SG04LP3-AU hybrid inverter and labelled deployed-firmware residues.
Codes involving DC/AC isolation, wiring or opening the unit are licensed electrical work. Isolate safely and follow AS/NZS procedure.

Resolution text is manufacturer/service context, not permission for an owner to perform electrical work. Stop at visible observations unless the exact product instructions identify an owner control. Isolation, configuration, testing, opening equipment and wiring are for an appropriately licensed worker and, where required, an SAA-accredited person. Where a card says Product fit is unknown, treat it as brand-level guidance and confirm the exact model, role, regional variant, firmware and current manual before acting.

F08
GFDI relay failure
The inverter's ground-fault detection (GFDI) relay has failed a self-test, or the neutral/earth bonding doesn't match the configured grid type. On deployed firmware and rebadged (Sunsynk) units this is one of the most-reported codes and is very often a grid-type setting mismatch (e.g. set to 120/240V split-phase when the system is actually single-phase) rather than a true hardware fault. (Note: the current official Deye AU and EU manuals do NOT list an F08 - they number the equivalent start/ground self-check as F07. Confirm against your unit's firmware.)
F13
Working mode / grid mode changed
An informational event, not a hardware fault. The official manual logs it when the grid type or frequency setting changes, when the battery mode is switched to 'No battery', or (on some older firmware) when the system work mode changes. It normally clears itself.

F35
No AC grid (AC_NoUtility_Fault)
The inverter cannot detect a valid utility grid - i.e. the grid is absent or out of acceptable voltage/frequency range. Often simply a grid outage or a tripped supply breaker; on three-phase units it can also be caused by incorrect phase rotation/sequence. (Note: this F35 numbering is from deployed/Sunsynk firmware; the current official Deye manuals do not list an F35 - confirm against your unit.)
F41
Parallel system stop
In a parallel installation, one inverter has shut down, which causes the other paralleled inverters to report F41 and stop as a group (official manual: 'if there is 1 pcs hybrid inverter shutdown, all hybrid inverters will report F41').

F46
Backup battery fault
A fault with the connected battery (or batteries). The official Deye AU and EU manuals decode F46 as 'backup battery fault' and advise checking each battery's status - voltage, SOC and parameter settings - and making sure all parameters match. (Earlier third-party lists mislabelled F46 as 'AC under-voltage'; the decoded official manuals do not support that - treat F46 as a battery fault.)
