1.) Two generators each on
one MPP tracker
2.) One generator on 1st tracker,
second tracker deactivated
3.) One generator parallel on both
MPP trackers
The MPP voltages of the two DC lines
can be diff erent.The MPP voltages of
the two DC paths can be diff erent.
They are tracked by separate, inde-
pendently operating MPP trackers
(MPP trackers A and B).
If one of the MPP trackers (A or B) is
not used, then it must be short-cir-
cuited, otherwise faults can occur
during the self-test of the unit and the
feed-in operation is not guaranteed.
The short-circuiting of an MPP tracker
does not result in the device being
damaged.
The DC inputs can also be connected
in parallel. In this case, only lines with
the same MPP voltage may be con-
nected in parallel (Un1=Un2=Unm).
The maximum permissible rated cur-
rent (DC) doubles with parallel connec-
tion of both MPP trackers.
In case of a parallel input connection,
MPP trackers A and B must be bridged.
Parallel operation is automatically rec-
ognized by the inverter.
Electrical data
I
max
Depending on PV generator.
The input current per tracker must not be exceed 11A.
≤ 2 * max. rated current (DC)
NOTE
Always use the 1 or 3 switch variant, before an MPP tracker is short-circuited and therefore remains
unused.
7.5.4 Connecting the PV generator
DANGER
Risk of fatal injury due to electric shock
Severe injury or death will result if the live connections are touched. When there is solar radiation, DC
voltage will be present at the open ends of the DC cables.
›
Do not touch the exposed ends of the cables.
›
Avoid short circuits.
Connecting the PV generator
1. Remove protective caps from the DC connection plugs.
2. Connect PV generator to the DC plug connectors on the underside of the housing.
3. Meet the requirements of protection rating IP65 by closing the unused plug connectors with protective caps.
4. Put on cover to safeguard the DC connections and latch into place by pressing it. (Figure 19 on page 20)
