Example: from 10:00 p.m. to 6:00 a.m., the load-shedding contactor is not to disconnect the loads from the
utility grid where possible.
Figure 25: Profile of the SOC thresholds for controlling the load-shedding contactor and the start times for the time periods
For the standard time period, the start time is set to 6:00 a.m. and the end time to 10:00 p.m. The lower SOC threshold
is set to 40% and the upper SOC threshold is set to 80% in this time period.
For the additional time period, the start time is set to 10:00 p.m. and the end time to 6:00 a.m. The lower SOC threshold
is set to 30% SOC and the upper SOC threshold is set to 40% SOC in this time period.
Requirement:
☐ In a cluster, the communication product or Sunny Remote Control must be connected to the master.
Procedure:
1. Log in to the communication product as Installer (see the user manual of the communication product) or switch to
expert mode on the Sunny Remote Control (see the Sunny Island operating manual).
2. Set the parameters for the standard time period:
• Select the parameter Time load shedding 1 / 242.05 Lod1Tm1Str and set to the start time for the standard
time period.
• Select the parameter Battery state of charge limit for load shedding 1 start / 242.01 Lod1SocTm1Str
and set it to the lower SOC threshold for the standard time period.
• Select the parameter Battery state of charge limit for load shedding 1 stop / 242.02 Lod1SocTm1Stp
and set it to the upper SOC threshold for the standard time period.
3. Set the parameters for the additional time period:
• Select the parameter Start time for the additional time period of load shedding 1 / 242.06 Lod1Tm2Str
and set to the start time for the additional time period.
• Select the parameter Battery state of charge limit for load shedding 1 start in the additional time period
/ 242.03 Lod1SocTm2Str and set it to the lower SOC threshold for the additional time period.
• Select the parameter Battery state of charge limit for load shedding 1 stop in the additional time period
/ 242.04 Lod1SocTm2Stp and set it to the upper SOC threshold for the additional time period.
4. Ensure that the multifunction relay used for control is set to AutoLod1Soc (see Section 8.1.5 "Setting the Functions
of the Multifunction Relays", page 71).
