DC Connector Kit GEN24
General The DC Connector Kit GEN24 (item number: 4,240,046) enables the connection
of PV connection strings with a total current above 28 A.
IMPORTANT!
If the Arc Fault Circuit Interrupter (AFCI) integrated in the inverter is used for
the requirement according to IEC 63027 for arc detection, DC Connector Kit
GEN24 must not be used. The installation must be carried out in accordance with
the nationally applicable standards and directives.
General com-
ments regarding
PV modules
To enable suitable PV modules to be chosen and to use the inverter as efficiently
as possible, it is important to bear the following points in mind:
-
If insolation is constant and the temperature is falling, the open-circuit
voltage of the PV modules will increase. The open-circuit voltage must not
exceed the maximum permissible system voltage. If the open-circuit voltage
exceeds the specified values, the inverter will be destroyed and all warranty
claims will be forfeited.
-
The temperature coefficients on the data sheet of the PV modules must be
observed.
-
Exact values for sizing the PV modules can be obtained using suitable calcu-
lation tools, such as the Fronius Solar.creator.
IMPORTANT!
Before connecting up the PV modules, check that the voltage for the PV mod-
ules specified by the manufacturer corresponds to the actual measured voltage.
IMPORTANT!
The PV modules connected to the in-
verter must comply with the IEC
61730 Class A standard.
IMPORTANT!
Solar module strings must not be
earthed.
Safety
WARNING!
Danger due to incorrect operation and incorrectly performed work.
This can result in serious injury and damage to property.
▶
Commissioning as well as maintenance and service work in the power module
of the inverter must only be carried out by service personnel trained by
Fronius and only within the scope of the respective technical regulations.
▶
Read the Installation and Operating Instructions before installing and com-
missioning the equipment.
