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 grid 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 the electrical safety standards IEC 62109. For this reason, it is not necessary to
include a residual current device between the unit and the grid.
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

CAUTION
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.
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.

5.7. Type of grid

These units can be connected to a single-phase (L-N-PE) or two-phase (L-L-PE) 220/240 Vac grid. They are not
compatible with Split-phase grids.
For single-phase grids (L-N-PE) the admissible grounding systems are TT and TN.

5.8. 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
