240V Split-Phase Power Architecture — Built for North American Homes
240V Split-Phase Power Architecture — Built for North American Homes
Breakthrough 240V Split-Phase Architecture for Real-World Home Grids
Most high-power DC chargers on the market mandate a 380V/480V three-phase commercial electrical supply, completely excluding private residences and light-commercial properties. The WAIZIDA Model D1W breaks this barrier with its proprietary dual-live-wire power conversion system, designed specifically for standard 220V–240V split-phase power networks (L1 + L2 + PE 3-wire input) widely used across North America and select international markets.
By connecting directly to existing 240V residential electrical panels, the Model D1W eliminates the exorbitant cost, lengthy permitting, and infrastructure upgrades required for industrial three-phase grid connections. It brings true DC fast charging within reach of private estates, suburban homes, multi-family garages, and off-grid solar-storage setups.
28kW Sweet-Spot Output — 4x Faster Than Standard AC Wallboxe
28kW DC Output: The Perfect Sweet Spot for Home Fast Charging
Covers charging gun temperature monitoring, over-voltage/under-voltage/overload protection, short circuit protection, lightning protection and more, delivering full-range safeguards for charging in all conditions.
Ultra-Compact Wall-Mounted Form Factor
Space-Saving Wall-Mounted Design with Residential Aesthetics
Unlike bulky, floor-standing commercial DC charging cabinets that require dedicated foundation pads and consume valuable parking space, the Model D1W is engineered with an ultra-compact wall-mounted form factor:
- 30% Smaller Footprint: Slim profile with a depth of just ~27.5 cm, preserving garage space and walkway clearance. - Flexible Mounting Options: Mounts easily onto garage walls, exterior brick/concrete surfaces, or on an optional standalone pedestal for outdoor driveways. - Acoustically Optimized for Homes: Smart thermal management and low-noise air cooling ensure quiet operation, maintaining neighborhood and household tranquility.
Choose between hassle-free Plug & Charge, secure RFID Card Swiping, or mobile App-based Control for family and authorized guest access.
Interactive 7-Inch LCD Touchscreen
High-resolution display provides real-time charging status, output voltage/current, accumulated energy (kWh), charging duration, and instant fault diagnostics.
OCPP 1.6J Cloud Connectivity
Integrated Ethernet, 4G, and Bluetooth options allow seamless connection to smart home EMS systems, third-party OCPP platforms, or remote management apps for scheduled charging, off-peak tariff optimization, and firmware updates.
Versatile Use Cases for Homeowners and Business Operators
Single & Multi-EV North American Households
The ultimate home upgrade for owners of high-capacity EVs (pickup trucks, large SUVs, daily commuters) seeking rapid battery recovery without relying on slow AC charging.
Luxury Detached Villas & Suburban Estates
Private estates with 240V split-phase utility service requiring a discreet, high-power wall-mounted charging station for private garages and courtyards.
Vacation Homes & Short-Term Rentals (Airbnb / VRBO)
Provides a premium, revenue-attracting fast-charging amenity for vacationers and tenants who need fast turnarounds before exploring local attractions.
Light Commercial Fleets & Executive Parking
Small businesses, corporate offices, medical clinics, and delivery fleets (4–6 vehicles) needing dedicated on-site fast charging without the massive capex of heavy commercial infrastructure.
Private Workshops, RV Parks & Car Enthusiast Garages
High-performance charging stations for custom workshops and off-grid solar-storage setups.
The WAIZIDA Model D1W is a pioneering 28kW wall-mounted DC fast EV charger engineered specifically to bridge the gap in residential and light-commercial EV charging. Built to solve the biggest limitation of traditional high-power DC chargers — their dependence on 380V three-phase industrial power — the Model D1W features an innovative dual-live-wire architecture designed for standard 220V–240V single-phase / split-phase electrical grids (L1 / L2 / PE 3-wire input), making it the ideal home DC fast-charging solution for North American residences, detached villas, private driveways, and modern residential garages.
Delivering up to 28kW of pure DC output, the Model D1W charges typical electric vehicles up to 4x faster than conventional 7kW Level 2 AC wallboxes — recovering a 60kWh battery from 20% to 80% in approximately 2 hours instead of 8.5 hours. With its ultra-compact wall-mounted form factor, intelligent 7-inch touchscreen, OCPP 1.6J connectivity, and multi-standard connector options (CCS1, CCS2, GB/T), the Model D1W delivers true commercial-grade DC charging speed straight to your private home.

Can the Model D1W be installed in a standard North American residential home?
Yes! The Model D1W is engineered with a dual-live-wire architecture specifically designed for 220V–240V split-phase power supplies (L1, L2, PE), which is the standard electrical configuration in North American residences. It does NOT require a 380V three-phase commercial connection.
How much faster is the D1W compared to my standard home AC charger?
The D1W delivers 28kW of direct DC power, which is up to 4x faster than standard 7kW Level 2 AC chargers. For an EV with a 60kWh battery, the D1W can charge from 20% to 80% in approximately 2 hours, compared to ~8.5 hours with a 7kW AC charger.
Which connector should I choose for North American electric vehicles?
For the US, Canadian, and Mexican markets, select the **CCS1** configuration. It connects directly to all CCS1-equipped EVs and can charge Tesla / NACS vehicles using an approved adapter.
Does the D1W require professional installation?
Yes. Due to the high continuous power output (28kW), installation must be performed by a licensed electrician who will evaluate your electrical panel capacity, breaker sizing, and wiring to ensure compliance with local electrical codes (such as NEC in North America).
