Value
Explanation
Off
Off; the multifunction relay is always in idle mode.
On
On; the multifunction relay is permanently activated.
AutoGn
Automatic generator request: the Sunny Island automatically requests the generator. In the
event of a generator request, the multifunction relay is activated.
AutoLodExt
1‑level load shedding
When the generator is connected, the Sunny Island stops the load shedding. When the loads
are to be shed, the multifunction relay is deactivated.
AutoLod1Soc
1‑level load shedding or first level of 2-level load shedding
When the upper SOC threshold is reached, the Sunny Island ends load shedding. When the
loads are to be shed, the multifunction relay is deactivated.
AutoLod2Soc
Second level of 2‑level load shedding
When the upper SOC threshold is reached, the Sunny Island ends load shedding. When the
loads are to be shed, the multifunction relay is deactivated.
Tm1
Timer 1
The Sunny Island controls external processes time-dependently. When the set time
