8.7.4.8 Schedule time
The schedule time pre-set allows to activate and deactivate the AC-Flex load relay in a daily base.
Restrictions can also be applied to avoid undesired activations. The parameters to setup this function
are:
Starting date
[secs from 01.01.1970]
Starting date of the scheduled daily activation-
deactivation. Before this date, the relay is disabled.
Starting time [secs from midnight]
Time of the day at which the relay is activated
Ending time [secs from midnight]
Time of the day at which the relay is deactivated
Allowed weekdays for relay activation.
Allow the relay to be daily activated each given week.
For example, with a value of 2 for this parameter, the
relay will be disabled every two weeks.
Range of recurrence selection
Selection of the ending of the recurrences:
• No end date: the daily activation-deactivation
continue indefinitely
• End after occurrence
• End date
8.7.4.9 On-grid
Activates the relay when inverter is connected to a source (AC-Source). Typically used when extra
loads require to be connected only with external source.
8.7.4.10 Cmd-entry
AC-Flex load contact is controlled by a command entry available in the system. This entry is selected
by entering its index number (available in CMD-IN settings). Any command entry in the system can
be used to activate-deactivate the relay.
8.7.4.11 Errors and warnings
AC-Flex load relay is controlled according to the system alarms. Errors and/or warnings can be used
to activate the relay. The following possibilities are available:
• Triggered by Errors
• Triggered by Warnings
• Triggered by errors and Warnings
8.7.4.12 Additional info regarding hysteresis operating mode
The following Pre-sets modes use a hysteresis-based logic to activate and deactivate the relay:
- Battery voltage
- Battery SOC
- Battery temperature
- Solar excess Ongrid
- Solar excess Offgrid
- On AC power
The hysteresis is given by 2 values configurable by the user: Activation threshold and deactivation
threshold. According to the numerical values set into the 2 thresholds, the hysteresis can follow 2
distinct behaviours (figure below). Having a value attributed to activation threshold higher than the
