SMA Solar Technology AG 7 Commissioning
Installation Manual SI80H-60H-OffGrid-IA-en-11 93
Requirement:
☐ In a cluster, the Sunny Remote Control must be connected to the master.
1. Switch to installer mode (see Section 7.5).
2. Setting the first level of load shedding:
• Select the 242.01 Lod1SocTm1Str parameter and set it to the lower SOC limiting value.
• Select the 242.02 Lod1SocTm1Stp parameter and set it to the upper SOC limiting value.
•Set the 242.05 Lod1Tm1Str and 242.06 Lod1Tm2Str parameters to the same value,
e.g. both to 000000. This switches off time-dependent load shedding.
• Ensure that the parameter of the multi-function relay is set to AutoLod1Soc
(see Section 7.10.2).
3. Setting the second level of load shedding:
• Select the 242.07 Lod2SocTm1Str parameter and set it to the lower SOC limiting value.
• Select the 242.08 Lod2SocTm1Stp parameter and set it to the upper SOC limiting value.
•Set the 242.11 Lod2Tm1Str and 242.12 Lod2Tm2Str parameters to the same value,
e.g. to 000000. This switches off time-dependent load shedding.
• Ensure that the parameter of the multi-function relay is set to AutoLod2Soc
(see Section 7.10.2).
7.10.5 Setting Time-Dependent 1-Level Load Shedding
Time-dependent load shedding divides the day into two intervals (see Section 7.7"Setting Time-
Dependent Functions",page89). You set the SOC limits that apply for each interval. For example,
you can set that as far as possible no loads are to be disconnected from the stand-alone grid during
the day.
Significance of the SOC limiting values:
When the state of charge of the battery reaches the lower SOC limiting value, the multi-function relay
opens the connected load-shedding contactor. The load-shedding contactor disconnects the loads
from the stand-alone grid. When the state of charge of the battery reaches the upper SOC limiting
value during recharging, the multi-function relay closes the connected load-shedding contactor. The
load-shedding contactor connects the loads to the stand-alone grid.
