SPH 3000–6000TL BL-UP / SPH 4000–10000TL3 BH-UP hybrid (Error 2xx–6xx codes)

Growatt PV2 short error code

PV2 input is short-circuited (displayed as 'Pv2 short').

Likely causes

  • Shorted PV2 string or connector
  • Reversed polarity on PV2
  • Damaged panel or DC cable on PV2
  • Water ingress in the PV2 connector

Checks to run, in order

  1. 1Shut the inverter down and isolate PV2
  2. 2Check the PV2 panel/string for a short with a meter
  3. 3Inspect PV2 connectors and cable for damage or water
  4. 4Compare PV2 and PV1 string voltages

Fixes

  • Repair or replace the faulty PV2 connector, cable or panel
  • Reconnect PV2 with correct polarity
  • Restart and confirm PV2 produces normally

When to escalate

If the PV2 string tests normal after shutdown and the message persists, ask Growatt support to check the PV2 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.
