Commercial Parking AC/DC EV Charging Solution
Mixed AC + DC charging infrastructure for shopping centres, office parks, hotels, and multi-tenant parking structures. Full OCPP backend integration with multi-tenant billing.
What charger mix works best for commercial parking lots?
Most commercial parking sites should use AC chargers as the base layer and DC fast chargers only where turnover or revenue justifies faster charging. Hotels, workplaces and malls often start with 7kW, 11kW or 22kW AC wallboxes for long-stay parking. A few 60kW to 150kW DC chargers can be added near entrances or premium bays for visitors who need faster sessions. OCPP, RFID, QR payment and POS scope should be confirmed before model selection.
AC base layer
Use 7kW, 11kW or 22kW wallboxes for hotel guests, tenants, employees and destination parking.
DC fast layer
Use 60kW, 120kW or 150kW DC chargers for retail turnover, public charging or paid fast service.
OCPP/payment
Confirm RFID cards, QR payment, POS terminal, billing reports and CSMS ownership before RFQ.
Expansion plan
Reserve electrical and cable routes for future bays instead of buying every charger at once.

Commercial site planning notes
For hotels and shopping centers, the charging plan should protect both guest experience and electrical cost. A good RFQ separates long-stay bays from high-turnover bays, because the AC/DC split affects charger cost, cable route, billing method and signage. If the site is open to public users, payment and support workflow should be decided before charger quantity is finalized.
Buyers should also clarify whether the site owner, tenant, operator or installer will manage the backend. That decision changes RFID account setup, QR payment flow, tariff reporting and after-sales responsibility. When SUNFULL reviews a commercial parking project, the most useful inputs are a parking layout, grid capacity, expected visitor stay time and whether the buyer wants free charging, paid charging or tenant reimbursement.
For distributor or EPC projects, ask the end customer to confirm cable routing, pedestal quantity, signage, local language labels and warranty handover before shipment. These small items often decide whether the first installation becomes a repeat project.
Questions buyers usually ask before the first quotation
Are AC chargers enough for commercial parking?+
They can be enough for long-stay parking. Sites with retail turnover or paid public charging usually add a small number of DC fast chargers.
How many DC chargers should a mall install?+
Start from traffic, available power, parking dwell time and revenue model. Many sites begin with AC coverage and a few DC fast bays.
Should commercial parking use OCPP?+
OCPP is recommended when the site needs billing, user accounts, remote monitoring, RFID or multi-site operator control.
The Challenge
Commercial site operators face three recurring problems: tenants who want dedicated billing, peak-hour grid overloads that trigger demand charges, and a fragmented mix of charger brands that cannot communicate with a single backend. The result is high operational cost and low charger utilization.
Our Approach
- AC base layer (7-22kW): Install AC wallboxes in covered bays for daytime dwell-time charging. Lower CAPEX, suits 2-4 hour stays.
- DC fast layer (60-120kW): 1-2 DC fast chargers near the entrance for EV drivers needing a quick top-up. Attracts footfall.
- Dynamic Load Management: Our OCPP smart charging profile automatically limits total site power draw to stay within your agreed grid connection capacity - eliminating demand charge spikes.
- Multi-tenant billing: Integrated with Chargepoint, Smappee, EV.energy or your own white-label CPMS. Each tenant or floor receives itemized energy billing.
- RFID + QR + App access: Visitors use QR scan or contactless payment; tenants use issued RFID cards. No friction, no attendant needed.

FAQ
How do I prevent overloading the building electrical connection?
Our Dynamic Load Management (DLM) system monitors total site power draw via CT clamps and automatically throttles charger output to keep the site within its agreed grid connection limit. No demand charge surprises.
Can different tenants be billed separately?
Yes. Each charger is assigned to a tenant group in the CPMS. Billing reports are generated per tenant, per period. We support white-label CPMS or integration with your existing billing system.
What is the minimum order for a commercial site?
No minimum order quantity for projects. We can supply from 1 charger. Projects above 20 units receive volume pricing and dedicated project engineering support.
How long does installation take?
A typical 20-charger AC install is 2-3 days with 2 electricians. DC charger installation adds 1 day per unit. We provide installation manuals, wiring diagrams, and remote commissioning support.
