Validate the 420 kW grid connection

Build a site model using vehicle arrivals, battery voltage, session energy, dwell time, simultaneous demand and expansion. Review utility service, transformer, switchgear, cables, protection, harmonics and demand management before equipment selection.

Confirm dual-gun power and current

The production record lists two guns, DC 50-1000 V output and a 300 A single-gun maximum. Obtain per-gun current-power curves, allocation logic, simultaneous limits, cable, connector and derating. Constant-power operation from DC 300-1000 V is optional.

Review continuous thermal operation

The description refers to power distribution and thermal management for continuous operation. Request model-specific module layout, cooling capacity, heat rejection, temperature derating, alarms, protection and endurance or acceptance evidence instead of treating the statement as a guarantee.

Coordinate the larger cabinet layout

The record lists 800 Ɨ 650 Ɨ 2000 mm dimensions, IP54, air cooling and floor installation. Check foundation, lifting, drainage, bollards, cable entry, clearances, ventilation, noise and service access against the final drawing.

Set communication and acceptance criteria

OCPP 1.6, Ethernet/4G and display functions are listed. Define firmware, CSMS, authorization, metering, reporting, cybersecurity and remote service. Connector compliance, payment integration, interoperability and charging time require separate evidence.

Frequently Asked Questions

No. Actual charging speed depends on the vehicle, battery, voltage, current, thermal limits, power allocation and site conditions.

The record lists a 300 A single-gun maximum. Request per-gun curves, total allocation and simultaneous limits across the required vehicle-voltage range.

Do not assume that they can. Confirm the module configuration, total power ceiling, sharing algorithm, vehicle voltages, cable limits and derating.

The current evidence does not establish a connector or market approval. Verify the exact configuration, label, drawing and documents for the destination country.

Include the vehicle and traffic model, grid and transformer data, gun allocation, connector, civil layout, thermal conditions, OCPP/CSMS, documents and destination.
