Solar PV Electrical Systems
Step-up transformers and electrical balance-of-plant equipment for solar generation projects, matched to your inverter configuration and grid interconnection point.
Overview
Utility-scale and distributed solar PV projects need step-up transformers and related electrical equipment matched to the inverter output configuration and the grid interconnection requirement. We coordinate this equipment through our manufacturing network, reviewed against your project's single-line diagram.
We have supported a real solar PV plant project as technical consultant and procurement coordinator — see Projects for the case reference.
Technical Considerations
Inverter output voltage and rated capacity
Step-up voltage ratio to the interconnection point
Outdoor rating, ambient temperature and altitude
Efficiency class relevant to long-term energy yield
Grid code compliance for the interconnection point
Compatibility with central or string inverter architecture
Exact specification is confirmed against your project's inverter datasheet and SLD — available upon project requirement.
Applicable Standards
Products can be supplied and tested in accordance with applicable IEC, IEEE/ANSI, CSA, GOST and destination-market requirements, subject to product type and manufacturing partner.
Customization Options
Voltage ratio, cooling method and enclosure protection class can be adapted to your inverter configuration and site condition through our manufacturing partners — confirmed per project.
Applications
Utility-Scale Solar Plants
Step-up transformers connecting inverter output to the grid interconnection point.
Commercial & Industrial Solar
