5.4 Connecting the Small Wind Turbine System (DC)
5.4.1 Conditions for the DC Connection
• The connection cables of the small wind turbine system must be fitted with connectors.
The DC connectors needed for DC connection are included in the delivery.
• The following limits at the DC input of the inverter must not be exceeded:
Maximum input voltage
Maximum input current
600 V
26 A
DANGER!
Danger to life through electric shock or fire
The maximum possible input current is limited by the connectors used. If the connectors are
overloaded, an electric arc may occur and there is a risk of fire.
• Ensure that the input current does not exceed the maximum through-fault current of
the connectors used.
NOTICE!
Destruction of the inverter due to overvoltage
If the voltage of the small wind turbine system exceeds the maximum input voltage of the
inverter, the inverter can be destroyed by overvoltage. This will void all warranty claims.
• Install overvoltage protection, e.g. Windy Boy Protection Box, between the small
wind turbine system and the inverter.
