SPF 3000TL LVM-ES / SPF 3500–5000 ES Lite off-grid (fault codes 01–81)
Growatt 60 error code
Negative power fault — power is flowing back into the AC input (F60 on the ES Lite).
Likely causes
- AC output connected to the grid input
- Program 8 setting different between parallel inverters
- Current-sharing cables not connected in the same parallel phase
- Neutral wires of parallel units not connected together
Checks to run, in order
- 1Check whether the AC output is connected to the grid input
- 2Check whether program 8 settings are the same for all parallel inverters
- 3Check the current-sharing cables in the same parallel phases
- 4Check that all neutral wires of parallel units are connected together
Fixes
- Correct the AC input/output wiring
- Match program 8 across the parallel system
- Reconnect the current-sharing and neutral wiring
When to escalate
If the problem still exists after these checks, contact 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.
Questions installers ask
What does Growatt 60 mean?
Negative power fault — power is flowing back into the AC input (F60 on the ES Lite).
How do I fix Growatt 60?
Correct the AC input/output wiring Match program 8 across the parallel system Reconnect the current-sharing and neutral wiring
When should I escalate Growatt 60?
If the problem still exists after these checks, contact a Growatt repair centre.
Can I reset Growatt 60 myself?
Only after isolating the AC and DC sides and running the checks above. If Growatt 60 returns immediately, stop resetting it and escalate; a repeating fault usually points to a real circuit, battery or hardware problem.
Which models show Growatt 60?
Growatt 60 is documented for SPF 3000TL LVM-ES / SPF 3500–5000 ES Lite off-grid (fault codes 01–81). Confirm the code on your own unit's display or manual before ordering parts.
More Growatt error codes
- Growatt 01Fan is locked (displayed as F01 on the SPF ES Lite).
- Growatt 02Internal component temperature is over 100 °C (F02 on the ES Lite).
- Growatt 03Battery is over-charged / battery voltage is too high (F03 on the ES Lite).
- Growatt 04Battery voltage low.
- Growatt 05Output is short-circuited (F05 on the ES Lite).
- Growatt 06Output voltage is too high. The manual groups 06/58 as 'output abnormal' — inverter voltage above 150 Vac or below 40 Vac.
