MW-Class Microgrid Switch Cabinet: 1.35/2.2MW High-Current Transfer
Summary: At MW scale the core shifts from single PCS to high-current transfer + system protection + distribution coordination. SP1350/2200H54SW for parks/stations.
Platform positioning
500–750kVA is skid-class; at MW scale the core shifts from "single PCS" to "high-current transfer + system protection + distribution coordination".
MW seamless switch cabinet
SP1350/2200H54SW (SP1350H54SW 1.35MW / SP2000H54SW 2.2MW): fast electromagnetic drive + solid-state arc extinguishing, supports 1.35/2.2MW PCS systems; high-speed transfer, power-flow management, ALL-IN-ONE deployment.
Selection points
Focus on working current, compatible voltage, break/make time and IP54 protection. Use cases: C&I parks, storage stations, PV-diesel microgrids, large island grids. Combine with SP125HCPS modules for a complete microgrid from module to MW.
FAQ
MW cabinet vs STS module?
STS module (200–600kW) serves single-system fast transfer; MW cabinet serves 1.35/2.2MW high-current system-level transfer and coordination.
How many PCS can it parallel?
Depends on system design; standard PCS paralleling has a limit (SP125HCPS 15); larger uses PCC controller + contactor (2.5MW mine).
Why parks/stations need it?
High-current seamless transfer and power-flow management ensure continuity and protection — a key MW distribution node.
SP1350H54SW vs SP2000H54SW?
Different capacity grades (1.35MW vs 2.2MW); choose by total PCS current and station scale.
