Guides
- How to read an error on a Growatt MIN inverter
The error message is shown on the OLED screen; a single touch switches the display. The manual notes that system faults are mainly caused by the system rather than the inverter.
- How to switch a Growatt MIN inverter off and on safely
Switch off the AC breaker and the DC switch, wait until the LED and display go out, then switch AC and DC back on. Never disconnect PV connectors under load.
- Growatt MIN: what the colour and blinking of the status LED mean
Green, red and yellow light patterns show standby, normal operation, fault, warning and programming. A touch switches the OLED display.
- Growatt MIN: what to prepare before calling service, and inverter care
The manual lists the information service needs (problem description, conditions, string layout). Clean the enclosure with a wet cloth only, without cleaning agents, and report damaged cables to the installer.
