5.3. LCD Display
The LCD display shows parameters of inverters which can be set through function keys. On the top,
it always shows working status and Ethernet status, The left area is for displaying parameter info or
energy wave; On the right, it always shows power, E-today, E-total; At the bottom of LCD display,
time and date will be shown (Figure 5-2 Main Interface 1)
When press “enter” button, it will go into main menu , telling inverter state, energy yield, as well as
device and malfunction info, and parameter setting; (Figure 5-2 Main Interface 2)
