Specification Sheet

The Fronius String Control 250/25 continually compares the strin g current outputs of multiple strings enabli ng 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.
