Sunny Island
Installation & Operating Instructions
much higher than the nominal power, simple halogen lamps extract up to 15 x of the
nominal power when they are turned on.
These consumers do not continuously require this high power, the Sunny Island
therefore does not have to be capable of generating this power. What is more impor-
tant is a sophisticated control strategy. When such loads are connected the Sunny
Island therefore reduces the AC voltage for a short time. This not only reduces the
current peaks on the AC side, but also those on the DC side – thus increasing the
battery power and prolonging the battery's service life.
