The 180kW 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 Every cabinet is load tested before shipment and arrives with a wiring map covering contactors, fuses and surge arrestors for fast commissioning. Bidirectional-ready bus design lets the same platform accept solar or battery energy storage input without a second conversion stage. Galvanic isolation between grid and vehicle protects both sides during fault events and meets the insulation requirements behind CE and IEC 61851 compliance. An active front end feeds isolated DC/DC stages inside each cabinet, so grid harmonics stay low while output voltage follows whatever the battery management system requests. Power conversion is separated from control logic, so firmware updates and diagnostics never interrupt an active charging session. Matching power modules are documented in the datasheet.

2. 200V-1000V Wide Voltage Output With Constant Power Output spans 200V to 1000V DC, covering 400V and 800V vehicle architectures from compact city cars to heavy-duty tractors. Continuous insulation monitoring isolates the outlet whenever leakage approaches the configured threshold, protecting technicians and vehicles alike. Wide range voltage tracking keeps efficiency above 95 percent even when a deeply depleted pack pulls close to the 250A current ceiling. A 1000V ceiling future-proofs the investment, because the same DC fast charging station serves today’s 400V fleets and tomorrow’s 800V platforms. 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 A shared DC bus lets any module feed any outlet, removing the fixed pairing that limits conventional charging piles. Module-level diagnostics flag degrading fans and capacitors long before they cause a stoppage, enabling condition-based maintenance. Modules slide out from the front, so service engineers never need rear clearance in tight parking layouts or wall-adjacent installations. Power is delivered by 30kW hot-swappable modules, so a failed unit is exchanged in minutes without isolating the whole cabinet. Speed-controlled fans and intelligent airflow keep acoustic noise near 65 dB, which suits residential, hospital and retail locations. Replacement modules ship pre-calibrated, and the controller recognises a new unit automatically once it is fully seated. Compatible EV charging connectors are listed separately.

4. Dynamic Power Allocation Across Dual Outlets Session logs record delivered energy per outlet, which simplifies billing, reconciliation and fleet cost allocation. Load balancing also watches site demand, trimming total draw when the transformer or building load approaches its limit. Because capacity follows demand, the DC fast charging station avoids the idle-outlet penalty that drags down utilisation on paired connectors. Dynamic power allocation distributes available capacity across outlets in real time, letting a single vehicle draw the full 180kW. 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. Site rules are tuned from the operator portal.

5. Outdoor IP55 Enclosure Built for Public Sites 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. The bonded anti-glare touchscreen stays readable in direct sunlight and remains responsive through gloved operation. Optional heating, ventilation and lighting kits extend operation to cold storage yards and dusty mining roads. Front and side service access is available, and the base frame accepts either anchor bolts or a concrete plinth. Cable management hooks keep CCS2 and CCS1 leads off the ground, extending connector life in busy public car parks. Installation drawings cover plinth and cable routing.

6. Smart Payment, OCPP Management and Energy Integration An open API and Modbus TCP option let the DC fast charger link with solar, storage and building management systems. 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. OCPP 1.6J adds certificate handling and stronger message security for public networks that must satisfy national roaming rules. The controller exposes smart charging profiles, so a central system can cap site load during peak tariff periods. Communication runs over OCPP 1.6J, so the station integrates with almost any back office without custom middleware. 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

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.

What output voltage range does the 180kW unit support?

The charger delivers 200V to 1000V DC at up to 250A, so it serves 400V passenger cars and 800V heavy vehicles from the same outlet. Constant power holds 180kW 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 180kW, 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.
