AC and DC coupling in perfect interaction and from a single manufacturer: the all-purpose Sunny Island Charger 50 by SMA. Its broad DC input voltage range makes configuration possible for almost any PV module. Thanks to the integrated MPP tracking system, the charger guarantees an energy yield between 15 to 30 percent higher than that of conventional shunt charge controllers. Unique in charge controllers of this power range: the high protection class, fanless operation and broad temperature range enable its use even under extreme climatic conditions. Easy installation and automatic control through the Sunny Island make commissioning super simple.
