Residual current device

These inverters are equipped with a residual current monitoring device that disconnects the unit if it detects a
residual fault current according to the electrical safety standards IEC 62109. For this reason, it is not necessary to
include a residual current device between the unit and the electricity grid.
This protection does not detect residual currents produced upstream of the inverter. If, for other reasons, it is
necessary to install a residual current device upstream of the inverter, this must be assigned to trip at a residual
current of at least 30 mA (type A or type B).

5.5. Wiring length

The inverter measures the voltage in its connection terminals. For this reason, the installer must use an AC cable
with a sufficiently low impedance so that increasing the voltage in the cable (between the distribution transformers
and the unit) does not cause the unit to be disconnected due to high voltage.

5.6. Photovoltaic panels

The photovoltaic panels of the installation must be Class A (IEC 61730).
