Buy Wallbox EV Charger | 22kW Dual-Gun Commercial EV Charging Station

Product Summary

The Wallbox EV Charger (22kW Dual-Gun AC Model) is a heavy-duty commercial electric vehicle charging solution engineered for fleet depots, EV supercharging station auxiliary charging, and B2B workplace charging. Featuring dual independently-managed Type 2 guns delivering 22kW per gun (11kW per gun in three-phase configuration), this unit integrates directly with your existing PV-storage-charging infrastructure. Powered by automotive-grade LFP battery architecture via DC-coupling (when paired with our Smart BESS), the unit supports dynamic load balancing, scheduled time-of-use charging, and full OCPP 1.6/2.0 remote fleet management. Global availability with 5-Year Performance Warranty and local O&M support in 30+ countries.

Why Choose This Wallbox EV Charger

For commercial distributors and energy service providers, the 22kW Wallbox delivers unmatched ROI through three core revenue mechanisms:

Peak Shaving & Time-of-Use Arbitrage: When paired with our 50kWh-500kWh C&I ESS, this charger stores low-cost off-peak energy and dispatches during peak price windows, reducing fleet charging costs by 38-52% (validated in EU CAISO and UK Grid markets).
Dynamic Load Management: The built-in EMS prevents site transformer overload by automatically throttling charging power down to 3.7kW per gun when combined site load exceeds 85% of rated capacity. No expensive grid upgrades required.
Lower Total Cost of Ownership: With IP65 rating, -30°C to 50°C operating range, and CE/TÜV/CHAdeMO (compatible) certifications, each unit is designed for 10+ years outdoor service life. Hot-swappable gun modules reduce mean time to repair to under 30 minutes.
Turnkey PV-Storage-Charging Solutions: Procure a complete solar + battery + Wallbox fleet from one source. Our logistics hub in Rotterdam, Houston, and Shanghai ensures 5-7 day lead time for standard configurations.

Product Overview & Safety Architecture

The Wallbox EV Charger features a passive thermal dissipation chassis (IP65-rated die-cast aluminum) with integrated humidity sensors and anti-condensation heating for extreme climates. The safety architecture includes:

AC/DC Residual Current Monitoring (Type A + 6mA DC): Independent relay cut-off within 0.04 seconds of detecting ground faults. Over-Voltage/Under-Voltage Protection: Automatic shutdown at 264V AC (single-phase) or 460V AC (three-phase) and auto-restart when grid stabilizes. Temperature Monitoring: Four thermocouple sensors monitor each power module and gun connector contact. Integrated Surge Protection (Type 2, 20kA): Meets IEC 61000-4-5 for direct lightning strike zones.
For B2B fleet operators, the unit includes insulation monitoring (IEC 62955-compliant) that continuously checks for EV-side DC leakage up to 1000VDC isolation.

Application Scenarios

EV Supercharging Stations (Hybrid Layout)

Deploy the 22kW Wallbox alongside 150kW-350kW DC fast chargers as a low-cost trickle-charge lane for plug-in hybrids and fleet vehicles with overnight dwell times. Our smart energy management prioritizes DC fast charger power from the grid while allowing Wallbox units to draw from a shared 200kWh BESS buffer. This eliminates demand charges and reduces per-kWh station operating costs by 23%.

Micro-grids & Industrial Parks

For manufacturing facilities, integrate the Wallbox with your rooftop PV (up to 100kWp) and 133kWh Liquid-Cooled ESS cabinet. The charger operates in island mode during grid outages—automatically disconnecting and drawing from the BESS to maintain critical fleet charging. Demonstrating sub-20ms switchover time, this configuration qualifies for business continuity power credit programs in Germany, Australia, and select US states.

Frequently Asked Questions

Q1: What is the lead time and MOQ for commercial distributors?

A: Standard configuration (22kW Dual-Gun, Type 2 socket, OCPP pre-loaded). MOQ of 10 units. Lead time: 7-12 days EXW Shanghai, 20 days Rotterdam CIF. Bulk orders (100+ units) can ship via 40HQ container within 18 days including certification labeling for your local market.

Q2: Does the Wallbox support V2H or V2G when paired with your battery system?

A: The current 22kW AC model does not support bi-directional DC V2G. However, it fully enables smart grid-integrated charging, meaning your BESS can discharge to EVs during peak rates. For true V2G, specify our Wallbox Bi-Directional DC model (20kW, available Q3 2026).

Q3: What is the cycle-life warranty for the BESS when paired with the charging station?

A: Our LFP battery packs (sold separately for PV-storage integration) carry a 10-Year Performance Warranty at 80% Depth of Discharge (70% end-of-life capacity). This covers daily peak shaving cycles (2 cycles/day, 4,000 cycles minimum). Derating curve: At 45°C ambient, expect 5,500 cycles to 70% SOH.

Q4: Can the Wallbox operate in off-grid or weak grid environments?

A: Yes with our Grid-Forming Hybrid Inverter (100kW-250kW model). The system supports seamless islanding and black start. Certified performance: Compliant with IEEE 1547-2018 and VDE-AR-N 4105 for frequency-watt and volt-var response down to 5% short-circuit ratio.

Q5: What local certifications and O&M support are available for my region?

A: Standard unit includes CE, UKCA, TÜV SÜD (EN 61851-1), and UL 2594 (pending for US SKU). We provide on-the-ground O&M via partners in: USA (Texas, California), Germany, France, Netherlands, Poland, Australia (NSW, Victoria), and the UAE. All firmware updates are pushed over-the-air via OCPP 2.0.
