Below is an example of how it can be applied:
a)
During the night, between 9.00pm and 6.00am, the mains power has a lower price and
therefore it can be used to charge the battery (this feature is not recommended with
CEI-201 standard).
b)
From 6 to 8 in the morning, the energy has a high cost and the production from the
photovoltaic system is low or zero, so the energy stored in the battery during the night
can be used to power the loads.
c)
From 8.00am to 7.00pm, the photovoltaic system will produce enough energy to charge
the battery and to power the loads at the same time.
d)
From 7 to 9 in the evening, the energy has a higher cost and the production from the
photovoltaic system is low or zero, so the energy stored in the battery during the night
can be used to power the loads.
The advantage of this procedure is therefore to use an “off-peak” period (e.g. at night) to charge
the batteries. Outside the charging period, the inverter returns to automatic mode.
The option to set the day of the week and months of the year allows greater flexibility in the
management of the charging procedure. For example, setting it only on weekends when
consumption is higher, or in the winter months when the inverter produces less power.
It is also possible to set multiple rules (or time slots) to satisfy even the most complex settings;
currently, a maximum of four time slots can be supported.
3)
Set Hourly Mode
Select “3. Set Hourly Mode”, then press “OK” to enter the interface of the set charge/discharge
mode. In this mode, it is possible to select a forced charging and discharging period for the
battery, as well as the power to be used for performing these operations.
Note: this mode is normally used to check that the 3000SP inverter is correctly charged and
discharged. Therefore, this mode is not recommended during normal operation of the system.
Below is an example of the screen.

4)
Set Passive Mode
Select “4. Set Passive Mode”, then press “OK”.
