01

Identify generation and supply

A concept topology represents the main relationships between the PV array, other supplies and the site electrical system. It is a planning aid rather than an installation drawing.

02

Find the conversion equipment

Identify the PV inverter, power conversion equipment or integrated solar-and-storage unit. The selected equipment determines the supported electrical interfaces and operating arrangements.

03

Trace battery and load interfaces

Review how battery equipment, building loads and charging equipment connect to the planned system. Cable sizes, protection and control details require project-specific design.

04

Understand the grid connection

A grid interface requires review of the local connection conditions, supply arrangement and protection requirements. Approval and implementation responsibilities are agreed for the project.

05

Move from concept to drawings

Use the concept to coordinate the scope, then request the project-specific electrical diagrams, equipment schedule and installation details from the responsible specialists.

Review scope depends on the site and available records.

Clear information helps the responsible specialists identify the next review and document the project scope.

Information checklist

Start with the information you already have. The exact document requirements depend on the project.

Information Why it helps
Available drawings and records Understand the building, system and existing equipment.
Site photos and conditions Review the setting, access and installation constraints.
Electricity-use information Review energy demand and the proposed operating arrangement.
Planned load changes Consider future demand and project phasing.
Project goals and constraints Match the review to the intended outcome.
Contacts and responsibilities Coordinate access, information and the agreed scope.
