PV plants and wind farms require complete electrical packages from DC collection to AC grid interconnection. CHBEST delivers PV combiner boxes, package substations (European/American type), and MV switchgear as integrated solutions for both utility-scale and distributed projects. Products are engineered for high-temperature, dust-resistant operation in the Middle East and Africa, proven in multiple overseas installations.
Pain Point:
PV array DC output requires collection, inversion, and step-up before grid connection.
Products:
PV combiner box → Package transformer (10kV/35kV) → MV switchgear.
Flow:
PV Modules → Combiner Box (DC 1000V/1500V) → Inverter → Package Substation (10kV/35kV) → Collector Line → Main Substation → Grid.
Pain Point:
Factory rooftop PV for self-consumption with surplus export to grid.
Products:
PV combiner box, dry-type transformer, LV switchgear.
Flow:
HV Incoming → Main Transformer → MV Switchgear → Feeder RMUs → End Users.
Pain Point:
Turbine output at 690V must be stepped up to 35kV for collection.
Products:
American-type compact package substation, ring main units.
Flow:
Wind Turbine → Tower LV Cabinet → Package Substation (690V→35kV) → Collector Line → Main Substation.
