10.1.1 Status messages
The Windy Boy 5000 / 6000 produces a range of status messages, depending on
the mode in which it is currently operating. The status messages can vary, depending
on the type of communications system you are using.
Derating Overtemperature in inverter ("WR"). The Windy Boy 5000 /
6000 reduces its performance to avoid overheating the device. To
avoid unnecessary yield losses, the configuration and string size
should be checked. Check if the Windy Boy 5000 / 6000 can be
located in a better position with better ventilation, thus providing
better heat dissipation.
Mpp The Windy Boy 5000 / 6000 is operating in MPP mode. The
Windy Boy 5000 / 6000 takes the highest possible performance
from the PV generator. MPP is the standard display when
operating with normal sunshine (PV operation only).
Island Mode The Windy Boy 5000 / 6000 is in Island Mode. This mode is
specially conceived for operation in a stand alone power system
with a Sunny Island as network controller. More information
about this topic can be obtained from the Sunny Island operating
manual under the category "Droop Mode".
grid mon. Testing the mains supply status (mains impedance), relay tests etc.
This message appears only during the startup phase, before the
Windy Boy 5000 / 6000 is connected to the mains supply. This
message mainly appears when there is little or no wind.
Offset Offset compensation of the measurement electronics
disturb. Fault (see table "Fault messages")
This fault occurs for reasons of safety and prevents the Windy Boy
5000 / 6000 from connecting to the mains supply. This mode can
also be manually set.
Stop Interruption of operation after a fault. This status can also be
manually set.
Turbine Mode Default setting for Windy Boy 5000 / 6000 inverters. The input
voltage is converted according to the V/I function U

V-Const Constant voltage operation (the input voltage is predefined. The
Windy Boy 5000 / 6000 operates in neither MPP mode nor
Turbine mode). In some cases, this can be set as the operational
mode.
