5.6. Cabling 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.

5.7. Photovoltaic panels

Standard IEC 62109 defines this inverter as a stand-alone inverter, and therefore the photovoltaic modules used
with it must be class A according to IEC 61730.
The stray capacity of the PV array must always be lower than:
• 11.3 μF if it is connected to a 50 Hz grid.
• 9.4 μF if it is connected to a 60 Hz grid.
The inverter cannot operate with grounded PV arrays; the PV array must be isolated.
The stray capacity depends mainly on two factors:
• Installation factors (structure, ceiling, etc.), inclination, manufacture of the photovoltaic module, type of
module.
• Environmental factors: humidity, rain, etc.
