SG125CX-P2 V21, string inverter
Product information
Practical features, high input currents, and cost-saving functions. The SG125CX-P2 from Sungrow leaves nothing to be desired. Whether as a standalone device or in large-scale systems – thanks to certification in accordance with VDE-AR-N 4105, 4110, and 4120, it's at home everywhere. Intelligent IV curve diagnostics, integrated Type 1+2 DC surge protection, and even AFCI 2.0 arc detection – all optimized for functionality and safety. With the V21 model version, strings with up to 30 amps of input current can be connected not only to an MPP tracker, but also to a single DC connection. Optimizers can also be used. This provides greater flexibility in DC design.
