Sunny Boy 700 Technical Description

5 Operation and Failure Indication LEDs

General
The inverter normally operates automatically, without user interaction and without
any maintenance. The inverter automatically turns itself off when a grid feeding is not
possible (e. g. at night).
The Sunny Boy automatically starts its grid feeding the next day once the solar radia-
tion is high enough. The inverter goes to standby mode if the radiation and the result-
ing electric input energy is too low and is therefore always ready for operation.
Each time the Sunny Boy starts up it runs a number of self tests and safety proce-
dures.
The green LED "Operation" indicates the current operation.
The red LED warns the user that an "Earth Fault" has occurred. A description of this
situation and what has to be done in that case is given in the section "Earth Fault
Indicator".
The yellow LED "Failure" indicates an internal or external failure that keeps the in-
verter from feeding the grid. The specific causes for this and how to avoid them are
described in detail in section "Failure Indication".
