5.5 Connecting the Small Wind Turbine System (DC)
5.5.1 Conditions for the DC Connection
• The connection cables of the small wind turbine system must be equipped with plug connectors.
You will find the necessary PV connector for DC connection in the delivery.
• The following limit values at the DC input of the inverter may not be exceeded:
Maximum input voltage Maximum input current
500 V 20 A
DANGER!
Risk of lethal electric shock or fire.
The maximum possible input current is limited by the plug connectors used. If the plug
connector is overloaded, an electric arc may occur and there is a fire risk.
• Ensure that the input current does not exceed the maximum flow current of the plug
connectors used.
NOTICE!
Destruction of the inverter by overvoltage.
If the voltage of the small wind turbine system exceeds the maximum input voltage of the
inverter, it can be destroyed by the overvoltage. All warranty claims become void.
• Install overvoltage protection, e.g. Windy Boy Protection Box, between the small
wind turbine system and the inverter.
