Main Screen

The LCD screen is touch-sensitive and displays general information about the inverter.

1 • The icon in the centre of the home screen indicates that the system is operating normally. If it displays "comm./F01~F64", this means that the inverter has communication errors or other errors. The error message will appear below this icon (errors F01-F64; details of the errors can be viewed in the System Alarms menu).

2 • The time is displayed at the top of the screen.

3 • System configuration icon. Press this button to access the system configuration screen, which includes basic configuration, battery configuration, grid configuration, system operating mode, generator port usage, advanced functions and Li-Ion battery information.

4 • The main screen displays information regarding solar, grid, load and battery. It also indicates the direction of energy flow using arrows. When power approaches a high level, the colour of the panels changes from green to red, allowing system information to be clearly viewed on the main screen.

- PV power and charging power always remain positive.

- A negative grid power reading indicates power being sold to the grid; a positive reading indicates power being drawn from the grid.

- A negative battery power reading indicates charging; a positive reading indicates discharging.
