90 SI80H-60H-OffGrid-IA-en-11 Installation Manual
Requirement:
☐ The Sunny Remote Control must be connected to the master of the main cluster.
1. Switch to installer mode (see Section 7.5).
2. Select the 242.01 Lod1SocTm1Str parameter and set it to the lower SOC limiting value.
3. Select the 242.02 Lod1SocTm1Stp parameter and set it to the upper SOC limiting value. The
upper SOC limiting value must be at least 10 percent greater than the lower SOC limiting value.
4. Set the 242.05 Lod1Tm1Str and 242.06 Lod1Tm2Str parameters to the same value,
e.g. both to 000000. This switches time-dependent load shedding off.
