SPF 3000TL LVM-ES / SPF 3500–5000 ES Lite off-grid (fault codes 01–81)

Growatt 05 error code

Output is short-circuited (F05 on the ES Lite).

Likely causes

  • Short in the AC output wiring
  • Faulty appliance plugged into the output
  • Water or damage in an output socket
  • Output cable pinched or cut

Checks to run, in order

  1. 1Disconnect the load and restart the unit
  2. 2Check that the wiring is connected correctly
  3. 3Inspect the output circuit for damaged insulation
  4. 4Reconnect loads one at a time to identify the faulty circuit

Fixes

  • Remove the abnormal load
  • Repair the shorted output wiring
  • Restart and confirm the output voltage is normal

When to escalate

If the output is clear with no load and fault 05 persists, return the unit to a Growatt repair centre.

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.
