2.4 Choice of inverters

The correct inverter and correct number
of DC isolators can be selected according
to the required number of PV panels.
Observe the max. number of panels per
string which can be connected to each
inverter.
Systems with more strings must always
be constructed with the same number of
panels.
VITOVOLT
The correct inverters for the system
output and the required number of
connection cables (which may also be
used as extension cables) to connect the
panel with the inverter and DC isolator
must be ordered separately.
The correct fixing set must be ordered
according to installation type.

Note
The correct routing of cables is an
important measure to protect against
induced excess voltages. Positive and
negative cables should be routed as
closely as possible to each other to keep
the area created by this power circuit and
therefore the induced excess voltages
small.

Frequently, this aspect is ignored or
neglected when routing cables, as a rigid
adherence to this consideration often
leads to longer cable runs and therefore
higher installation costs. However, for the
sake of effective excess voltage
protection, this aspect should be taken
into consideration.
