Growatt error 117: Relay fault
Growatt error code 117 usually means the inverter has detected a relay fault or relay circuit failure.
The relay is part of the inverter’s safety and grid connection function. It helps control how the inverter connects to and disconnects from the grid. When this fault appears, the inverter may stop producing power or disconnect from the grid as a safety response.
This is not a normal operating message and should not be ignored if it keeps appearing. A relay fault may be linked to an internal inverter issue, grid connection problem, control board fault or another electrical fault within the system.
Book a solar inverter check with e-Solar
If Growatt error code 117 appears once and clears after a restart, the inverter may have recovered from a temporary relay issue. However, do not keep repeatedly resetting the inverter without knowing why the fault is occurring.
If the code keeps returning, your solar output has dropped, or the inverter is no longer operating normally, it is worth having the system checked.
Our Perth solar experts can inspect the inverter safely, review the fault history and help determine whether the issue is linked to the relay circuit, internal hardware, grid connection, firmware behaviour or another system fault.
Contact e-Solar and let us know:
- The exact error code on the screen or app
- When the code appears
- Whether your solar production has dropped
- Your inverter model, if you know it
Do not open the inverter or attempt electrical testing yourself. If the issue is persistent, a qualified technician may need to assess the relay circuit, internal electronics, grid connection and warranty status before recommending repair, replacement or further action.
Growatt error code 117 is commonly associated with a relay fault. A restart may clear a temporary fault, but if the code returns, the system should be professionally assessed to determine whether there is an internal relay, control board or grid connection issue.
If you’re unsure, don’t risk it. Contact e-Solar for safe, local support.
