Build the site in two layers. Put EV-ACT3204E wallboxes on the staff bays, where cars sit for the working day and an RFID card decides who can charge. Put EV-AC03201T dual-connector stations on the visitor and shared bays, where two connectors on one foundation serve shorter stays and the OCPP platform keeps the records. Size the electrical supply against the two products’ combined ceiling, and roll the build out starting where cars dwell longest.
Key Takeaways
- Split the site by dwell: wallboxes per staff bay, dual-connector stations on the bays that turn over.
- Size the supply on the combined ceiling — wallboxes at 22 kW each plus 43 kW per station — labelled as ceilings.
- Load balancing across the two products is not a stated feature; it is a written confirmation to request.
- Roll out from the longest dwell outward, and let session records justify each next phase.
Two Products, Two Jobs
| Layer | Product | Bays it suits | What it contributes |
|---|---|---|---|
| Staff layer | EV-ACT3204PE wallbox, one per bay | All-day staff parking | 22 kW per bay; RFID and app access; tethered Type 2 cable |
| Shared layer | EV-AC03201T station | Visitor and shared bays | Two Type 2 connectors per foundation; up to 43 kW shared; touchscreen and RFID start; OCPP 1.6J session records |
The split follows dwell time. Staff cars arrive and stay, so a point per bay with card access is the whole requirement. Visitor and shared bays turn over, so connectors per foundation and a platform record matter more than a point each. Forcing one product to do both jobs either strands visitor cars at staff posts or spends station money on cars that sit still for eight hours.
The Load Picture, in Ceilings
Work in ceilings, and label them as such. As an example: six wallboxes at 22 kW each give a 132 kW ceiling; one dual-connector station adds 43 kW; the design conversation with your electrician starts from a 175 kW combined ceiling. Real draw will be lower, and rarely simultaneous at full rate — but supplies are designed against ceilings, not hopes.
What neither product page promises is load management across the site. Balancing between units is not a stated feature of either product. Inside the station, its stated dynamic allocation works between its own two connectors only. So if your supply cannot carry the combined ceiling, treat cross-product balancing as a written confirmation to request from us, and a phasing decision — not as a feature to assume in the design.
Roll Out Where Dwell Is Longest
- Phase one: staff wallboxes. Predictable users and all-day windows forgive a modest count, and card access gives you clean session data from the first week.
- Phase two: the shared station. Add it when visitor and shared demand is visible in that data rather than guessed at the planning meeting.
- Policy is yours. Who may use the visitor bays, and how the shared connectors rotate, is the employer’s own document — our guide to planning a workplace charging program covers how sites set it.
The same records then justify the next step: a second station is a decision the platform data can support, not an optimism to fund on day one. See our commercial charging solutions for the range in context.
Frequently Asked Questions
Can both products report into one platform?
The station states OCPP 1.6J; the wallbox states RFID and app control. A single back office spanning both is not something the product pages promise, so ask us in writing before designing the site around it.
Do I need the station if I already have wallboxes?
Only when shorter-stay or shared demand exists. All-day staff are fully served a bay at a time; the station earns its place on turnover, not on staff dwell.
What if our supply cannot carry the combined ceiling?
Phase the build, and ask us in writing what load arrangements are supported. Do not assume cross-product balancing that the pages do not state; your electrician designs against the ceilings you actually install.
