The 150kW 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 Power conversion is separated from control logic, so firmware updates and diagnostics never interrupt an active charging session. A single controller supervises rectification, isolation and metering, which keeps the power path short and trims conversion losses across the whole load range. Bidirectional-ready bus design lets the same platform accept solar or battery energy storage input without a second conversion stage. Busbar layout, magnetic components and cooling channels are shared across the 150kW family, which shortens lead times and simplifies spare part stocking. Input power factor stays above 0.99 and the wide input window keeps operation stable on weak rural feeders and long industrial spurs. 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 250A current ceiling. Pre-charge sequencing limits inrush current, shielding vehicle contactors and DC link capacitors from stress during every plug-in. Voltage and current limits are negotiated over the control pilot, then confirmed by the battery management system before the DC contactors close. Precision metering at the outlet delivers Class B accuracy, so billed energy matches what the vehicle actually receives. 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.

3. 30kW Hot-Swap Power Modules and N+1 Redundancy Power is delivered by 30kW hot-swappable modules, so a failed unit is exchanged in minutes without isolating the whole cabinet. N plus one redundancy keeps rated 150kW available even while one module is pulled for service, which matters on revenue-critical corridors. Thermal design holds junction temperatures stable at 50 degrees ambient, so the DC fast charger sustains rated output in hot climates. Each module reports voltage, current, temperature and fan speed to the controller, which derates or isolates any unit drifting out of tolerance. Modules slide out from the front, so service engineers never need rear clearance in tight parking layouts or wall-adjacent installations. Compatible EV charging connectors are listed separately.

4. Dynamic Power Allocation Across Dual Outlets Scheduling profiles prioritise buses in the morning and light vehicles in the evening without manual intervention. Because capacity follows demand, the DC fast charging station avoids the idle-outlet penalty that drags down utilisation on paired connectors. When a second connector activates, the controller splits output according to state of charge rather than a fixed schedule. Operators set allocation rules per site, per connector or per tariff window through the cloud portal, with no on-site reprogramming. Session logs record delivered energy per outlet, which simplifies billing, reconciliation and fleet cost allocation. Priority rules can reserve one outlet for emergency fleets while the other follows a normal queue, all configured remotely. 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. Front and side service access is available, and the base frame accepts either anchor bolts or a concrete plinth. Surge protection, residual current detection and emergency stop are integrated, and the cabinet is engineered for a ten-year outdoor service life. 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. A powder-coated steel body with anti-corrosion treatment suits coastal, industrial and roadside installations. 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. Remote diagnostics, firmware updates and tariff changes are pushed over the air, cutting truck rolls for routine maintenance. Every session produces a metered record covering start, stop and energy delivered, mapping directly to the operator’s billing engine. 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. 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 150kW 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 150kW 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.

As a commercial DC fast charger, the platform is specified for operators who need predictable uptime from a DC fast charging station.

Fleet managers comparing a DC fast charging station against split systems value the single-cabinet service model of this DC fast charger.

The DC fast charging station ships with commissioning support, and every DC fast charger is backed by regional spares.

Choosing a DC fast charger with documented test reports keeps procurement audits simple for any commercial EV charger project.
