the battery reaches The battery remains on standby waiting for the
the minimum SOC solar panel power in order to charge, while the

When solar panel power is available, it is used
to charge the battery. This state is maintained
until SOC ≥ min. SOC + 5%. Once this state is
exited, the overall load power prioritisation is
restored.

the battery, if not, it discharges it to supply the

connected to the grid as the battery keeps it
always on. This is not necessary in Off-Grid
mode, as there is never a grid in this mode.

Why isn't the hybrid One of the following solutions may resolve this
version optimal and issue:
why does it import -Depending on the type of battery, it must be
from the grid when fully charged first.
it has battery power -The PeakLoad Shifting option is enabled and
available? therefore the battery does not discharge until it
reaches a power consumption higher than Pmax
(this parameter can be configured from the app).
Disable this option and try.
-The battery type is configured incorrectly. It can
be configured from the inverter display or from
the app.
-DOD is too low. A DOD between 80% and 90%
is recommended. This parameter is configured
from the app.

4.5.2. OFF-Grid mode.

4.5.2.1. Brief introduction.
In Off-Grid mode, the grid is never available, so only the back-up
load can be supplied. The first priority is to make use of the solar
panel power, and if it covers the back-up consumption, the sur-
pluses are used to charge the battery. In the event that the solar
panel power is not sufficient, the shortfalls are covered with the
battery.
The battery system must be connected to the inverter for
this work mode to function.

Answers
The installation's consumption is supplied first of all by the power
generated by the solar panels; if the consumption is higher, the bat-
tery power is used, and if it is lower, the battery is charged with the
surpluses from the solar panels.

4.5.3. UPS mode.

4.5.3.1. Brief introduction.
UPS mode seeks to charge the battery in the shortest possible time
in order to be prepared in the event of a possible power outage and
thus be able to supply as much energy as possible.
UPS mode kicks in when the grid is lost, so there are two possible
states:

UPS OFF mode: In this state, there is a grid and the aim is to
charge the battery at maximum power, so all of the solar panel
power is used for the battery and, if it is not enough, the grid
