Electrical distribution requirements
Solar and energy projects require coordination between generation equipment, auxiliary power, grid connection and downstream distribution. Zejiefu focuses on switchgear, distribution-board and enclosure scope defined in the project documents. Inverters, protection studies and grid-code compliance remain subject to the responsible system designer and approved specification.
Typical equipment scope
- AC collection or auxiliary LV distribution boards
- Main switchgear for approved distribution points
- Outdoor boxes and enclosures for auxiliary circuits
- APFC or power-quality equipment supported by study data
Project information to provide
- Plant SLD and equipment boundaries
- Inverter output and auxiliary-load schedules
- Fault level and protection requirements
- Outdoor environment and enclosure requirements
- Communication, metering and grid-interface points
Engineering and delivery workflow
A quotation should distinguish the generation package from the electrical-distribution scope. The submitted SLD, BOQ and specification are reviewed to identify ratings, interfaces and exclusions. Approved drawings then control assembly, inspection, packing and delivery.

Prepare the RFQ documents
Use the SLD and BOQ preparation guide to align ratings, feeder references, installation requirements and document revisions before submitting the project.
Frequently asked questions
Is the inverter included in the switchgear quotation?
Only when it is explicitly included in the confirmed supply boundary. The RFQ should separate inverter, grid-interface and distribution-equipment responsibilities.
What documents are needed for an AC distribution quotation?
Provide the plant SLD, inverter output data, auxiliary-load schedule, fault level, enclosure conditions and required monitoring interfaces.
Request a project review
Send the available SLD, BOQ, equipment schedule, destination country and required delivery date. Missing information can be identified during the first technical review.
