Growatt PairingTime Out error code

The inverter timed out trying to pair with the SP-CT (communication fault).

Likely causes

  • SP-CT too far from the inverter
  • SP-CT not powered
  • SP-CT not put into pairing mode
  • Radio interference between SP-CT and inverter

Checks to run, in order

  1. 1Check the distance between SP-CT and inverter is within the specified range
  2. 2Check the SP-CT is powered
  3. 3Restart the inverter and SP-CT
  4. 4Re-run the CT pairing from the inverter menu

Fixes

  • Move the SP-CT closer to the inverter
  • Power-cycle the SP-CT and re-pair
  • Restart the inverter and confirm the CT reading is live

When to escalate

If the SP-CT is powered, in range and still will not pair, ask Growatt support to replace or service the SP-CT.

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.
