12.2 Temporarily connected Generators
In plants with a scarce battery storage capacity and without a motorized generator,
i. e. where the only feeders are photovoltaic or wind generators, it may become nec-
essary to have the battery recharged by a mobile generator. This can be the case
when unfavorable weather conditions persist for a longer time period.
For this purpose the operator can use a special terminal box available from SMA as
an accessory (SMA order code “SI-GENCASE.01“) which can be firmly installed in
the plant. The circuit diagram is shown in Fig. 12.5. The figure also shows the con-
nection of an external generator in different operating modes and includes instruc-
tions for operation.
According to the current configuration, it may be necessary to change several pa-
rameters, so that the following settings apply:
Parameter Value
401_Phase Mode
1Phs_Single (see Chapter 8.4)
602_GenSet Type

be deacti-
vated (menu „GENSET“ (2-2), see Chapter 7.2).
