What to do if my Growatt SPI 3000 Inverter shows Inc OCP Dec OCP const OCP?
- R
  Russell RamirezAug 18, 2025
  If your Growatt Inverter displays 'Inc OCP Dec OCP const OCP', it could be due to several reasons: the pump load might be too large, the solar array voltage could be too low, the motor wiring might be too long, the inverter power may be insufficient, or there could be a short circuit. To resolve this, try replacing the pump with a smaller one, checking the solar array voltage, shortening the wiring between the inverter and motor, selecting an inverter with larger power, or checking for short circuits in the load.

Why does my Growatt Inverter display Inc OVP Dec OVP Const OVP?
- C
  Chad BarajasAug 21, 2025
  If your Growatt Inverter shows 'Inc OVP Dec OVP Const OVP', it indicates that the input voltage is too high, or there is large energy feedback. To fix this, check the voltage of the solar array and verify if the deceleration time of the load is too short, or if the inverter starts during motor rotation.

What causes Overload Pump error on a Growatt SPI 3000 Inverter?
- H
  Heather BallardAug 23, 2025
  If your Growatt Inverter is showing an 'Overload Pump' error, it could be due to an incorrect motor rated current setting, low input voltage, an improper motor overload protection threshold, or a motor block or sudden load change. You can reset the motor's rated current, inspect the input power supply, set a proper motor rated current, and check the load, adjusting the torque boost as needed.

Why is my Growatt SPI 3000 showing Inv Overtemp?
- W
  William RobertsAug 26, 2025
  If your Growatt Inverter displays 'Inv Overtemp', it could be due to blocked air flow, high environmental temperature, prolonged overload running, or a control board issue. To resolve this, clean the air flue or improve ventilation, lower the environmental temperature, select a proper motor, or ask for support.

How to fix Overload VF error on Growatt Inverter?
- D
  donna06Aug 28, 2025
  If your Growatt Inverter displays 'Overload VF', it could be due to a too-short acceleration time, restarting a rotating motor, low input voltage or a heavy load. To solve this, increase the acceleration time, avoid restarting after power off, check the power supply, or select a bigger capacity inverter.

What does Bus low mean on a Growatt Inverter?
- C
  Colleen LeonardAug 30, 2025
  If your Growatt Inverter shows 'Bus low', it means the input voltage is too low or the illumination intensity is too weak. Check the voltage of the solar array.

What does Phase out loss mean on a Growatt SPI 3000 Inverter?
- R
  Rachel PerezSep 1, 2025
  If your Growatt Inverter displays 'Phase out loss', it means there is a phase loss of U, V, W output or a serious unbalance in 3-phase input. To solve this, check the output distribution, the motor, and the cable.

What causes Curr fault on a Growatt SPI 3000 Inverter?
- E
  Elizabeth RaySep 3, 2025
  If your Growatt Inverter is showing 'Curr fault', it may be due to poor contact in the control board connection, damage to the hall component, or an abnormal magnifying circuit. You can check the connector and rewire it, replace the hall component, or replace the main control panel.

What does IGBT short mean on a Growatt SPI 3000?
- D
  David AustinSep 6, 2025
  If your Growatt Inverter displays 'IGBT short', it indicates an output short circuit or grounding module damage. Check the wiring.
