2.5 Connection
Before connecting, always compare the indicated voltages of the
photovoltaic solar inverter. These values must match.
Before connecting your PV modules to the photovoltaic solar inverter,
check whether this is suitable for operation with your PV modules.
When reading off the values, note that PV modules achieve a higher open
circuit voltage at lower temperatures and unchanged solar radiation.
The EFFEKTA Regeltechnik GmbH Company is not liable for damage
caused by this to the PV modules and to the photovoltaic solar inverter.
2.8 Working with PV modules
Wrongly polarised connections cause the fuses in the photovoltaic solar
inverter to blow out and can result in longterm damage to the device.
Our warranty does not cover damage that is caused by reverse polarity.
Make sure that all connections are firmly in place, since loose
connections overheat and represent a potential danger.
The operation of the photovoltaic solar inverter without a correct
grounded contact can cause electrical safety hazards.
The requirements for the earthing vary depending on the country and the
application. All installations must meet the requirements of the applicable
national regulations.
You must use suitable power cables, e.g. cable diameter, insulation, VDE-
approved and CE-labelled, with appropriate cable ends for the connection
of the photovoltaic solar inverter to the PV modules.
Use only a VDE-approved and CE-labelled power cable with the appropriate
cable diameter to connect the PV modules to the photovoltaic solar inverter. Do
not connect any PV modules to the photovoltaic solar inverter, which could
overload the device (take note of the high starting currents).
Dangers such as stumbling, squeezing, clipping, etc. are to be avoided with the
cables.
