The 240kW multi-gun DCDC solar-battery fast charger targets industrial microgrids and solar carports, where uptime and quick service access decide revenue. With CCS2 and CCS1 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. DCDC Solar-Battery Power Topology and Conversion Chain Efficiency peaks at 96 percent and stays above 94 percent from light load to full output, cutting energy cost for high-utilisation sites. Power conversion is separated from control logic, so firmware updates and diagnostics never interrupt an active charging session. The 240kW multi-gun unit is built around a DCDC solar-battery topology that rectifies three-phase AC input onto a regulated DC bus before power reaches the vehicle inlet. Busbar layout, magnetic components and cooling channels are shared across the 240kW family, which shortens lead times and simplifies spare part stocking. 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. Cable assemblies rated 250A to 400A are matched to each outlet, and CCS2 and CCS1 leads are available in lengths from 4 to 8 metres. Pre-charge sequencing limits inrush current, shielding vehicle contactors and DC link capacitors from stress during every plug-in. Precision metering at the outlet delivers Class B accuracy, so billed energy matches what the vehicle actually receives. Voltage and current limits are negotiated over the control pilot, then confirmed by the battery management system before the DC contactors close.

3. 30kW Hot-Swap Power Modules and N+1 Redundancy Each module reports voltage, current, temperature and fan speed to the controller, which derates or isolates any unit drifting out of tolerance. A shared DC bus lets any module feed any outlet, removing the fixed pairing that limits conventional charging piles. N plus one redundancy keeps rated 240kW available even while one module is pulled for service, which matters on revenue-critical corridors. Modules slide out from the front, so service engineers never need rear clearance in tight parking layouts or wall-adjacent installations. Thermal design holds junction temperatures stable at 50 degrees ambient, so the DC fast charger sustains rated output in hot climates. Compatible EV charging connectors are listed separately.

4. Dynamic Power Allocation Across Dual Outlets Matrix switching allows any module to serve any gun, so one cabinet can run a single 400A session or two lower-current sessions. When a second connector activates, the controller splits output according to state of charge rather than a fixed schedule. Session logs record delivered energy per outlet, which simplifies billing, reconciliation and fleet cost allocation. Scheduling profiles prioritise buses in the morning and light vehicles in the evening without manual intervention. Operators set allocation rules per site, per connector or per tariff window through the cloud portal, with no on-site reprogramming. Load balancing also watches site demand, trimming total draw when the transformer or building load approaches its limit. Site rules are tuned from the operator portal.

5. Outdoor IP55 Enclosure Built for Public Sites Cable management hooks keep CCS2 and CCS1 leads off the ground, extending connector life in busy public car parks. A powder-coated steel body with anti-corrosion treatment suits coastal, industrial and roadside installations. The bonded anti-glare touchscreen stays readable in direct sunlight and remains responsive through gloved operation. Each unit is ingress tested at the factory and ships with CE documentation covering insulation and earth continuity checks. Front and side service access is available, and the base frame accepts either anchor bolts or a concrete plinth. Optional heating, ventilation and lighting kits extend operation to cold storage yards and dusty mining roads. Installation drawings cover plinth and cable routing.

6. Smart Payment, OCPP Management and Energy Integration Multi-language interface, configurable tariff screens and branded start pages help operators monetise the charging session itself. OCPP 1.6J adds certificate handling and stronger message security for public networks that must satisfy national roaming rules. Local storage keeps sessions running if connectivity drops, then synchronises records once the link returns. Communication runs over OCPP 1.6J, so the station integrates with almost any back office without custom middleware. Drivers authenticate by RFID card, mobile app, QR code or ISO 15118 plug and charge, with an optional POS terminal for bank card payment. The controller exposes smart charging profiles, so a central system can cap site load during peak tariff periods. 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

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.

What output voltage range does the 240kW unit support?

The charger delivers 200V to 1000V DC at up to 400A, so it serves 400V passenger cars and 800V heavy vehicles from the same outlet. Constant power holds 240kW from about 500V upward, which shortens charging time on modern high-voltage packs.

How does DCDC architecture differ from a conventional AC-DC charger?

A DCDC stage accepts a DC bus from solar or battery storage and converts it directly, skipping one rectification step. That raises round-trip efficiency and lets the DCDC solar-battery platform operate during grid outages when paired with a BESS cabinet.

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.
