Define the project objective before placing equipment
Site planning starts with the operating objective, not with a cabinet footprint. Clarify whether the project is intended for demand management, solar self-consumption, backup planning, a controlled operating trial or another defined use case. Rank any competing objectives so the design team knows which duty has priority when the battery cannot reserve the same energy for every purpose.
Document the expected operating window, target electrical interface and anticipated expansion in the project brief. This gives the owner, engineer and supplier a common basis for discussing equipment location and system scope without assuming a final configuration too early.
Collect the site information suppliers need
A useful early package includes the available electrical drawings, interval load data where relevant, transformer and connection information, site layout, access routes, operating hours and the locations of other critical equipment. It should also identify onsite generation, planned new loads and any restrictions set by the owner, utility or landlord.
Mark unknowns rather than filling gaps with estimates. A supplier can then state the assumptions used for its concept, while the project team can schedule the surveys, measurements or authority discussions needed to close each gap.
- Point of connection and existing protection information
- Available equipment area, delivery route and service access
- Load, generation and operating-schedule information
- Target use cases and energy-reserve priorities
- Known planning, environmental or owner constraints
Plan electrical and civil interfaces together
The cabinet location affects cable routes, voltage drop, protection coordination, communications, foundations and installation sequencing. Review these interfaces as one site plan instead of treating the cabinet as an isolated item. The preferred location should support safe delivery, commissioning and later maintenance without creating avoidable conflicts with daily site operations.
Ask the project engineer to confirm the final connection concept, earthing approach, protection settings and applicable electrical rules. Equipment literature can guide early comparison, but the final design must follow the approved single-line diagram, the confirmed equipment specification and local requirements.
Leave safety, access and maintenance decisions to the approved design
Site layouts need space for routine inspection, service work, emergency access and the procedures that apply if equipment must be isolated. Exact clearances, fire measures, drainage, ventilation, noise treatment and environmental protections are project-specific. They should be set by qualified designers using the approved datasheet and the requirements of the local authority and site owner.
During procurement, ask each supplier to identify the installation conditions, maintenance access needs, environmental limits and items that remain outside its supply. This makes it easier to detect a proposal that assumes site work or protective measures are someone else’s responsibility.
Confirm controls, communications and operating ownership
A cabinet project also needs a clear operating model. Define who approves control priorities, who receives alarms, who can isolate equipment, how communications connect to the site systems and who has authority to change settings after commissioning. The control scope should distinguish between equipment monitoring, site-level energy management and any utility or third-party interface.
Request an interface list with the proposal. It should name the required signals, communications responsibilities, cybersecurity expectations, commissioning inputs and the documents the owner will receive at handover.
Turn the checklist into a comparable supplier brief
Before requesting final offers, issue the same site information and evaluation questions to every supplier. Ask them to state the proposed configuration, assumptions, exclusions, electrical and civil interfaces, installation responsibilities, operating limits and documents required before commissioning. Avoid comparing offers only by a headline capacity figure.
The result should be a decision record that shows what is confirmed, what still needs engineering review and which assumptions could change the scope. Final product selection and site design should be completed only after the local requirements and approved equipment documentation have been confirmed.
