These are the questions installers and homeowners ask most often when troubleshooting Felicity Solar equipment.
- What does the F07 error code mean on a Felicity inverter?
- F07 indicates that the battery voltage exceeds the maximum allowed value for your inverter. Check that the battery pack specifications and the number of batteries in the bank match the inverter's rated input range. If the configuration is correct, the issue is usually a charge-controller setpoint that needs adjustment.
- How do I clear a critical Felicity error code?
- For most critical codes you should disconnect AC and DC, wait 60 seconds, then power back on. If the error returns immediately, do not bypass it — the inverter has detected a hardware issue or unsafe operating condition. Note the exact code, the device model number, and contact an authorized Felicity service partner. Every code in this directory shows the source manual and page so your technician has the exact context.
- Is the difference between F-codes and C-codes important?
- Yes. F-codes are inverter or ESS faults — typically PV, output, or hardware events. C-codes are battery or BMS protection events — overcharge, over-discharge, cell-balance, or temperature. The fix path is different: F-codes usually involve checking inputs and outputs at the inverter, C-codes involve the battery configuration and may require BMS reset.
- Are these the same codes that appear in the Felicity user manual?
- Yes. Every entry in this directory is sourced directly from official Felicity Solar user manuals. The "Source" line at the bottom of each code lists the exact manual filename and page number. We compile across 46 source manuals so you don't have to search each one separately.
- My device is not in the list — what should I do?
- The directory currently covers 44 Felicity devices across batteries, inverters, ESS units, charge controllers, and EV chargers. If your device isn't listed, check whether your model is covered as a variant of a similar device — the device pages list "also covers" model numbers. If still not found, contact Felicity support with your model number; we update this directory as new manuals are released.
- Can I troubleshoot a Felicity inverter myself?
- Many warning-level codes (W-prefix) and operational issues can be safely cleared by following the recommended fix in this directory. Critical and fault-level codes — especially those involving short-circuits, IGBT failures, or BMS hardware errors — require an authorized Felicity service technician. When in doubt, the recommended-fix block on each code page tells you whether the action is safe for an end user or requires a professional.
