The following table serves as a guideline for dimen-
sioning the photovoltaic power needed depending on
the climatic conditions:
Climatic conditions
Countries with low sunshine
e.g. Northern and Central Europe
Sunny countries
e.g. Southern Europe and Africa
These values given are guidelines. Depending on the conditions
prevailing on site and the specific conditions of consumption, the
appropriate design of the photovoltaic output may vary from the
values described.
Extension of the photovoltaic line:
When extending the photovoltaic cable, the MC4
contact plugs must be properly attached to ensure
functionality and safety. Basically, the PV cable
should be kept as short as possible.
A length recommendation depending on the
connected nominal PV generator power can be found
in the following table.

Connection of an external AC
Reheating:
IMPORTANT!
Only use certified connection plugs
(IEC-320 - C13 plugs) recommended by the
manufacturer. Non-compliance will invalidate the
warranty and may damage the water heater. The
external reheating feature extended use of the
photovoltaic boilers. For example, long periods of
bad weather can be bridged by connected AC power.

factory default.
Quick guide: System modes
Mode 1: Photovoltaic
For the direct connection of photovoltaic modules. If
desired plus a fothermo AC-reheating via mains
current.
Mode 2: PV Battery
For the connection of other energy sources such as a
battery. A battery cable is needed to plug in the
battery via MC4-connectors. The battery is not
included. More detailed information can be found in
the respective product description.
WARNING! When setting the battery DCH Voltage
(discharge voltage), it is important to consider the
voltage loss
in the cables connecting the water
heater with the battery.
