SPH 3000–6000TL BL-UP / SPH 4000–10000TL3 BH-UP hybrid (Error 2xx–6xx codes)
Growatt PV1 short error code
PV1 input is short-circuited (displayed as 'Pv1 short').
Likely causes
- Shorted PV1 string or connector
- Reversed polarity on PV1
- Damaged panel or DC cable on PV1
- Water ingress in the PV1 connector
Checks to run, in order
- 1Shut the inverter down and isolate PV1
- 2Check the PV1 panel/string for a short with a meter
- 3Inspect PV1 connectors and cable for damage or water
- 4Compare PV1 and PV2 string voltages
Fixes
- Repair or replace the faulty PV1 connector, cable or panel
- Reconnect PV1 with correct polarity
- Restart and confirm PV1 produces normally
When to escalate
If the PV1 string tests normal after shutdown and the message persists, ask Growatt support to check the PV1 input circuit.
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 PV1 short mean?
PV1 input is short-circuited (displayed as 'Pv1 short').
How do I fix Growatt PV1 short?
Repair or replace the faulty PV1 connector, cable or panel Reconnect PV1 with correct polarity Restart and confirm PV1 produces normally
When should I escalate Growatt PV1 short?
If the PV1 string tests normal after shutdown and the message persists, ask Growatt support to check the PV1 input circuit.
Can I reset Growatt PV1 short myself?
Only after isolating the AC and DC sides and running the checks above. If Growatt PV1 short returns immediately, stop resetting it and escalate; a repeating fault usually points to a real circuit, battery or hardware problem.
Which models show Growatt PV1 short?
Growatt PV1 short is documented for SPH 3000–6000TL BL-UP / SPH 4000–10000TL3 BH-UP hybrid (Error 2xx–6xx codes). Confirm the code on your own unit's display or manual before ordering parts.
