Light backlight and single knock to check running information
Before light the backlight, the four types of knock functions are the same, which is
just lighting the backlight. Note that the background lighting will automatically turn
off if there is no knock detected in 10 seconds.
During cloudy days or in the area of low light, it’s inconvenient for users to check
inverter running information such as state, input data, output data, energy
generated. In this case user can light the backlight and check those data by single
knock, a single knock will switch LCD screen to a following interface. The interface
display on LCD screen will circle as follow: Fir6.3.8 -> Fig6.3.9 -> Fig 6.3.10 ->
Fig6.3.11-> Fig6.3.12, and then again Fig6.3.8.
