UPS ON mode : In this state, the energy from the solar panels
and the battery are used to supply the back-up load, always
prioritising the use of the solar panels.

UPS OFF mode indicates that there is a grid and, therefore,
the UPS mode is disabled. In this state, the solar panel power pri-
oritises charging the battery, and if this is not enough to charge it
at maximum power, the grid is used for this purpose and to supply
the installation's consumption. On the other hand, if the power
from the solar panels covers the needs for charging the battery at
maximum power, their surpluses are used to supply the installa-
tion's consumption and, if not, use of the grid is prioritised.

UPS ON mode indicates that there is no grid and therefore the
UPS is enabled. In this state, there is only the consumption of the
back-up load and priority is given to supplying it with the power
generated from the solar panels. If this is not enough, then the
battery power is used, but if the power from the solar panels
is sufficient to cover the back-up consumption, the battery is
charged with their surpluses.
Questions Answers
1 What is the
maximum Back-up
Load power?
The maximum Back-up Load power is 110% of the
rated power of the inverter
2
What is the
maximum
generation power?
In UPS OFF, the maximum generation power is that
limited by PAC. In UPS ON, the maximum generation
power is higher than PAC.
3 Is there
a prioritisation
between load and
Back-up Load?
In UPS OFF there is no prioritisation, in UPS ON there
is only the back-up load.
4 What happens if
the battery reaches
the minimum SOC
(maximum DOD)?
In UPS OFF mode, operation remains the same,
the battery charges from PV+Grid and the loads are
supplied from the grid (provided there are no PV
surpluses).
In UPS ON mode, the battery remains on standby
if there are no solar panels and the back-up load is
not supplied. If there are solar panels, the battery is
charged to SOC ≥ min. SOC + 5%, then the back-up
load is supplied.

4.5.4. Economy mode.
4.5.4.1. Brief introduction.
In Economy mode there are four different states:
Discharge
,
PV charge
,
PV + Grid charge
and
Standby
. The four modes
can be configured from the app and are linked to the battery's
behaviour. From the app, the user can configure an economic plan
and decide at what time of day the battery should be charged or
discharged.
In the case of the charging option, it is broken down into two
other options: PV or PV + Grid ; the PV option prioritises battery
charging from the solar panels and the installation's consump-
tion is supplied from the grid and from the solar panel surpluses,
if any. The PV+Grid option prioritises battery charging from the
solar panels and from the grid, and the installation's consumption
is supplied from the grid and from the solar panel surpluses, if any.
If the time range defined in the charging/discharging app does not
reach 24 hours, the default state is standby. In this state, the hy-
brid behaves like an inverter without batteries.
