The 240kW dual-gun modular AC-DC fast charger targets public parking hubs and retail destinations, where uptime and quick service access decide revenue. With CCS1 and NACS outlets, a 200V-1000V DC window and OCPP 1.6J connectivity, it delivers predictable high-power charging while keeping installation and commissioning simple. This DC fast charging station pairs high utilisation with low maintenance overhead.

1. Modular AC-DC Power Topology and Conversion Chain Galvanic isolation between grid and vehicle protects both sides during fault events and meets the insulation requirements behind CE and IEC 61851 compliance. Input power factor stays above 0.99 and the wide input window keeps operation stable on weak rural feeders and long industrial spurs. Power conversion is separated from control logic, so firmware updates and diagnostics never interrupt an active charging session. Efficiency peaks at 96 percent and stays above 94 percent from light load to full output, cutting energy cost for high-utilisation sites. Bidirectional-ready bus design lets the same platform accept solar or battery energy storage input without a second conversion stage. Matching power modules are documented in the datasheet.

2. 200V-1000V Wide Voltage Output With Constant Power Wide range voltage tracking keeps efficiency above 95 percent even when a deeply depleted pack pulls close to the 400A current ceiling. Output spans 200V to 1000V DC, covering 400V and 800V vehicle architectures from compact city cars to heavy-duty tractors. Precision metering at the outlet delivers Class B accuracy, so billed energy matches what the vehicle actually receives. A 1000V ceiling future-proofs the investment, because the same DC fast charging station serves today’s 400V fleets and tomorrow’s 800V platforms. Continuous insulation monitoring isolates the outlet whenever leakage approaches the configured threshold, protecting technicians and vehicles alike.

3. 30kW Hot-Swap Power Modules and N+1 Redundancy N plus one redundancy keeps rated 240kW available even while one module is pulled for service, which matters on revenue-critical corridors. Module-level diagnostics flag degrading fans and capacitors long before they cause a stoppage, enabling condition-based maintenance. Speed-controlled fans and intelligent airflow keep acoustic noise near 65 dB, which suits residential, hospital and retail locations. Modules slide out from the front, so service engineers never need rear clearance in tight parking layouts or wall-adjacent installations. A shared DC bus lets any module feed any outlet, removing the fixed pairing that limits conventional charging piles. Commissioning takes under an hour with the guided setup wizard. Compatible EV charging connectors are listed separately.

4. Dynamic Power Allocation Across Dual Outlets Priority rules can reserve one outlet for emergency fleets while the other follows a normal queue, all configured remotely. Scheduling profiles prioritise buses in the morning and light vehicles in the evening without manual intervention. When a second connector activates, the controller splits output according to state of charge rather than a fixed schedule. Dynamic power allocation distributes available capacity across outlets in real time, letting a single vehicle draw the full 240kW. Because capacity follows demand, the DC fast charging station avoids the idle-outlet penalty that drags down utilisation on paired connectors. Session logs record delivered energy per outlet, which simplifies billing, reconciliation and fleet cost allocation. Site rules are tuned from the operator portal.

5. Outdoor IP55 Enclosure Built for Public Sites Cable management hooks keep CCS1 and NACS leads off the ground, extending connector life in busy public car parks. The bonded anti-glare touchscreen stays readable in direct sunlight and remains responsive through gloved operation. The enclosure is rated IP55, with filtered intake louvres and a sealed electronics compartment that shrugs off rain, dust and washdown. A powder-coated steel body with anti-corrosion treatment suits coastal, industrial and roadside installations. Ambient range runs from minus 30 to plus 55 degrees Celsius, with internal heaters protecting the 7-inch display in freezing conditions. Front and side service access is available, and the base frame accepts either anchor bolts or a concrete plinth. Installation drawings cover plinth and cable routing.

6. Smart Payment, OCPP Management and Energy Integration Every session produces a metered record covering start, stop and energy delivered, mapping directly to the operator’s billing engine. Remote diagnostics, firmware updates and tariff changes are pushed over the air, cutting truck rolls for routine maintenance. An open API and Modbus TCP option let the DC fast charger link with solar, storage and building management systems. Drivers authenticate by RFID card, mobile app, QR code or ISO 15118 plug and charge, with an optional POS terminal for bank card payment. Multi-language interface, configurable tariff screens and branded start pages help operators monetise the charging session itself. Backend integration follows the OCPP specification.

Deployment Support and Accessories

Projects usually pair the cabinet with Type 2 to Type 2 cables and a OCPP protocol controllers, all supplied from one factory. Engineering teams can review the company profile before order, while commercial questions go through the contact our team page. Standard builds ship in four to six weeks, and documentation covers wiring, grounding and network setup.

Frequently Asked Questions

Can the two guns charge at the same time at full power?

Yes, with dynamic allocation. Total capacity is shared, so one vehicle can take the full 240kW, or two vehicles can split it according to state of charge. Matrix switching means any module can serve either outlet, and rules are configured remotely.

Which OCPP version should an operator choose?

OCPP 1.6J covers the widest installed base of back offices today. OCPP 1.6J is specified here for certificate handling, plug and charge support and stronger message security. Both profiles work with standard roaming hubs, and the protocol controller datasheet explains the mapping.

What protection level is needed for roadside installation?

IP55 is the baseline for outdoor public sites, combined with surge arrestors, residual current detection and an emergency stop. Coastal or dusty locations should add the anti-corrosion coating and filter service kit.

How is maintenance handled when a power module fails?

Modules are hot-swappable from the front. A technician isolates the affected unit, slides it out and seats a pre-calibrated replacement while the second outlet keeps serving traffic. N plus one redundancy keeps rated output available throughout.

Does the station support solar and battery storage integration?

The DC bus is storage-ready. Solar MPPT or a BESS cabinet can feed the link directly, and the controller can cap grid import during peak tariffs. This suits microgrid and carport projects where demand charges dominate operating cost.

What payment options are available for public drivers?

RFID card, mobile app, QR code, ISO 15118 plug and charge and an optional POS terminal for contactless bank cards. All methods write to the same metered session record, so reconciliation stays simple. Connector options are listed on our EV charging connector page.
