FAULTS & WARNINGS
When a problem occurs in the system, the Inverter will beep and inform the user on the GUI. The Inverter
displays two basic error messages. The first, the fault, is a serious problem that causes the inverter to stop
running. The second, a warning, is a minor problem that does not cease the system operation. The GUI will
indicate faults in red and warnings in yellow. The user can find a description of the different fault and
warnings in the following tables.
