When selecting the protection in an installation you must take into account that its breaking capacity is greater
than the short-circuit current of the auxiliary connection point.
You must also take into account that the working temperature influences the maximum current permitted by these
protections as indicated by the manufacturer.
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 electrical safety standard IEC 62109.
This protection does not detect residual currents produced upstream of the inverter. If it is necessary to install a
residual current device upstream of the inverter, it must have a residual current lower than the maximum effective
current that can be generated in the photovoltaic installation in any of its operating conditions.
The grounding capacity of the photovoltaic modules varies depending on the technology they are manufactured
with. During the grid injection, a diverted current is produced from the cells to earth, whose value depends on the
assembly of the modules and environmental conditions (rain, snow, etc.).

5.6. Storage system connection protection

It is mandatory to install a continuous current switch between the inverter and the battery bank. It must have
appropriate dimensions to open the battery bank, taking into account the maximum charge and discharge current.
These inverters do not admit grounding of the batteries. Therefore, the battery bank terminals must be isolated
from ground. Otherwise the inverter will give an insulation fault.

5.7. Battery cabling length

The inverter measures the battery voltage in its connection terminals. For this reason, the installer must use a DC
cable with a sufficiently low impedance to prevent the battery charge/discharge process from causing the unit to
disconnect due to high or low battery voltage (see section "8.2. Wiring requirements for connecting the storage
system").

5.8. Auxiliary genset cabling length

The inverter measures the genset voltage in its connection terminals. For this reason, the installer must use an
AC cable with a sufficiently low impedance to prevent the current absorption/injection from causing the unit to
disconnect due to high or low grid voltage (see section "10.2. Wiring requirements for connecting the auxiliary
genset").

5.9. Protection of the connection to the PV plant

It is mandatory to install a DC switch on the connection between the inverter and the PV plant. It must be
dimensioned to open the PV array.
In Australia, the unit is supplied without a DC switch. The installer will have to install an external DC switch that
complies with Australian regulations, especially the AS 60947.3:2018 standard.
This DC switch will have the following nominal values:
