*The Grid and Load outputs in normal grid operation will be the same as they are
internally connected, however, in case of grid failure, if the system stays running
in off-grid, the inverter opens the contact that joins the grid and load and leaves
the load output running in off-grid. This is because the inverter cannot operate in
island mode, therefore the automatic must be separated from the frame so that
it can operate in off-grid. The operation in off-grid will depend on whether the
corresponding batteries have been installed and will operate by solar energy
and batteries only for the duration of renewable energy. It should be noted that
the power will be limited to 10 kW (and 32A per phase), therefore it is not possible
to include loads that require a lot of power.
5.1 Installation options
Option 1
For load currents lower than 32A per phase (around 7.2kW), the general
connection of the SunBox will be as shown in the following diagram:
It is the simplest configuration and avoids manipulation of the load connections.
As all the power from the network passes through the equipment (Load output)
and it distributes the energy, it implies that the maximum current of the loads is
32A per phase in self-consumption mode (around 7.2kW), and 32A per phase
and 10kW in total when there is no grid.
