Fronius 4,240,140,800 String Control 250/25US and Smart Combiner Box

The Fronius String Control 250/25 continually compares the string current outputs of multiple strings enabling the early detection and localization of problems within the entire system. Up to 25 module strings can be combined and every string is protected with its own DC fuse. As a result, there is nothing to stand in the way of reliable energy production.
