Schneider Electric PV Skid Optimized solar power conversion system tailored to enhance any North American PV power plant 1
PV Skid solution Integrated solution designed for optimal performance in any environment Introducing a compact, configurable, global reach, solar power conversion system The Schneider Electric PV Skid solution is a UL compliant power conversion system combining critical PV system components to achieve optimal power plant performance. PV Skid is available in configurations ranging from 1 MW to 2 MW and incorporates the latest offering from Schneider Electric, the Conext Core XC-NA inverters along with a medium voltage transformer, DC recombiners, and auxiliary switchboard for local loads and field tracker motors (optional) all pre-wired and factory tested on a single skid. The integrated solution also offers an optional remote control operation using Schneider Electric s SCADA system, Conext Control. The Type 3R rated outdoor solution was designed to operate to temperatures down to -35 C and comes with an optional shade canopy for sun and rain protection. It is suitable for installation on compacted soil, gravel, or concrete stabs/piers offering maximum flexibility. The PV Skid solution allows a reduction of balance-of-system costs, increased reliability, and faster deployment. 2
