3.3 Operating States
The different operating states are displayed with three LEDs in the lid of the Sunny
Boy 3300TL.
You will find a complete description of all signal codes in chapter 3.3.4 "Description
of Operating States" (page 12). The operating states can be divided into three cate-
gories:
3.3.1 Normal Operating States
As long as no LED or only the green LED is blinking, the Sunny Boy 3300TL is in one
of its normal operating states. If all three LEDs are on, the inverter is in its initialization
phase which is a normal operating state as well. All other signals indicate a disturbed
operating state.
Especially in the first year after installation the operator of the plant
should regularly have a look at this display at different times of the day
and at different irradiation.
