Changing the Current Thresholds for the Generator
Qualified person
The basic procedure for changing operating parameters is explained in another section ( > Changing Operating Parameters).
Significance of the current limits:
The generator management limits the consumption of generator current to the maximum set value.
In three-phase systems, the generator current is limited for each line conductor individually. The set value applies to each line conductor.
For Sunny Island inverters that are operated in parallel, the generator management only limits the total generator current. The generator current may be unequally distributed to the Sunny Island inverters. If a Sunny Island fails, for example, more current flows through the remaining Sunny Island inverters.
Enhanced generator management:
If the set generator current is not sufficient for supplying the loads, the generator management requests additional current from the battery. The system then supplies the loads with the generator current and the battery current.
Procedure:
- Select Generator > Generator.
- Set the parameter Rated generator current to the desired value. Tip: A suitable value for the Rated generator current is 80% of the maximum generator current per line conductor.
