The work modes that can be selected according to the installation's
requirements are detailed below:
4.5.1. General mode.
4.5.1.1. Brief introduction.
General mode seeks a balance. It prioritises the supply of loads using
the solar panel power, and if the consumption is lower than the photo-
voltaic generation and therefore there are surpluses, they are used to
charge the battery. On the other hand, if consumption is higher than the
photovoltaic generation, the battery is used, and if consumption is still
higher, the grid is used.

The system will power the loads using the energy produced by
the solar panels whenever possible. If this is not enough (either
because the installation's consumption is higher, or because the
generation is lower due to weather conditions), the energy stored
in the batteries* will be used. The sum of both will not be greater
than the rated power of the inverter.
As a last resort, in case the two previous sources are not enough
or the consumption is greater than the rated power of the inverter,
the system will add the missing energy from the grid.
*The batteries will be charged solely with the energy from
the solar panels. They will never be charged from the grid,
except when the charge level of the batteries is critical and they
are charged from the grid for their protection.
4.5.1.3. Operation of the “PeakLoad” function
In
General mode
, the "peak consumption" mode can be selected
for installations that have high occasional consumption and want
to reduce the total power contracted, using the batteries to cover
the consumption peaks instead of using more power from the grid.
For this function, the
P
MAX
parameter must be defined: limit on
power to be imported from the grid. The system will prevent more
power being imported from the grid than the configured limit,
providing the remaining power needed from the photovoltaic
generation and/or from the batteries, as defined in the following
scenarios. Please note that the system will constantly import the
P
MAX
limit value from the grid.
