Description
11: DroopMains The Sunny Island is operated to-
gether with an utility in droop
mode.
12: DrpGenMains
The Sunny Island is oper-
ated together with a generator
capable of droop characteristic-
sand an untility in droop mode.
13: BHKW-Isl-Therm
Sunny Island is operated
together with the ecopower CHP.
In difference to “BHKW-Island”
the Sunny Island will not switch
off the CHP when no more elec-
trical power is needed. So the
ecopower CHP will be able to
provide as much thermal energy
as needed
