Description

Wallbox Quasar Bidirectional DC EV Charger

7.4kW Bidirectional DC Charging for Selected EVs

Charge your EV, and where supported, use your EV battery as an energy storage resource.

Wallbox Quasar is a compact bidirectional DC EV charger designed for selected CHAdeMO-compatible electric vehicles. Unlike normal AC chargers, Quasar connects directly through DC charging and can support two-way energy flow where the vehicle, electrical installation and local regulations allow.

It is designed for users interested in Vehicle-to-Home (V2H), Vehicle-to-Grid (V2G), energy storage, off-peak charging and smarter home energy management.

Quasar supports myWallbox app control, Wi-Fi, Ethernet, Bluetooth, optional 3G / 4G, RFID access, face recognition and gesture-based user interaction.

Price and Availability

Pricing, availability and compatibility should be confirmed before purchase because bidirectional charging depends on vehicle support, local approval and site requirements.

Important: Quasar is not a generic Type 2 AC charger. It is a DC bidirectional charger for compatible CHAdeMO vehicles only.

Why Choose Wallbox Quasar?

Most EV chargers only allow electricity to flow from the building to the car. Quasar is different. It is designed to allow energy to flow both ways, from grid to vehicle and, where supported, from vehicle back to the home or grid.

This makes Quasar suitable for early adopters, energy-conscious homeowners, solar users and customers who want to explore using their EV battery as part of a wider energy management system.

Quasar is suitable when the objective is not only EV charging, but also potential EV battery utilisation for V2H, V2G, peak cost reduction and energy resilience.

V2H and V2G functionality must be reviewed carefully. It depends on EV compatibility, utility requirements, local regulations, protection arrangement, metering arrangement and system approval.

Bidirectional Charging: What It Means

Charge Your EV

Use Quasar as a compact DC charger to charge compatible CHAdeMO EVs at up to 7.4kW.

Vehicle-to-Home

Where supported, energy stored in the EV battery may be used to support selected home energy needs.

Vehicle-to-Grid

Where permitted by local utility rules, energy may be exported back to the grid through approved V2G arrangements.

Solar Energy Utilisation

In suitable systems, surplus solar energy can be stored in the EV battery and used later.

Peak Cost Management

Charge during lower tariff periods and discharge during higher tariff periods where the system and tariff arrangement support it.

Energy Storage Alternative

For compatible vehicles, the EV battery can act like a large energy storage resource when the vehicle is parked and connected.

Features Overview

The following visual summarises the smart charging features typically presented for Wallbox EV chargers.

Wallbox Quasar Smart Bidirectional EV Charger Features

Smart Charging Features

Revolutionary

Bidirectional technology allows compatible EVs to charge and discharge, turning the vehicle battery into a useful energy resource.

Innovative

A compact smart DC charger designed for home and selected light commercial energy management applications.

Controllable

Schedule charging sessions, monitor charger status and manage charging through the myWallbox app.

Connected

Connect through Wi-Fi, Bluetooth, Ethernet or optional 3G / 4G for smart charger operation.

Onboard Intelligence

Bluetooth support allows local charger management even when the parking area has poor internet coverage.

V2X

V2H / V2G Potential

Supports bidirectional use cases where the EV, installation, utility and local regulations allow two-way power flow.

Compatibility Matters

Before offering or installing Quasar, compatibility must be checked carefully. It is not suitable for every EV.

CHAdeMO Vehicle Required

Quasar is intended for compatible EVs with CHAdeMO DC charging connection.

Not a Type 2 AC Charger

Quasar is a DC bidirectional charger. For normal Type 2 AC charging, consider Wallbox Pulsar, Copper SB or Commander 2.

V2H / V2G Depends on Approval

Discharging to the home or grid may require additional protection, metering, grid approval and utility acceptance.

Installation Package

The installation package must be finalised after site assessment because Quasar is a DC bidirectional charger and may require additional engineering review compared with normal AC chargers.

7.4kW Installation Package

EV junction box enclosure
1 phase 2 pole MCB 32A branded
1 phase 2 pole RCCB 40A branded
1 phase 2 pole isolator switch 32A branded
Up to 15m of 2.5mm x 3C PVC cable with PVC conduit
Supply, installation, commissioning and training

Final protection design may vary depending on bidirectional function, local approval, earthing system, EV compatibility and utility requirements.

Supply, Installation, Testing and Commissioning

We can support Wallbox Quasar selection, installation review, commissioning and user training. Because Quasar is bidirectional, it should be assessed more carefully than a standard AC EV charger.

Vehicle and Function Check

Confirm EV model, CHAdeMO compatibility, required charging function and whether V2H / V2G is intended.

Site Electrical Assessment

Review supply type, DB location, earthing, protection, cable route, charger location and network requirements.

Commissioning and User Setup

Commission charger, verify operation, assist with myWallbox setup and guide the user on charging and bidirectional functions.

For bidirectional systems, proper protection selection, earthing verification, trip testing, anti-islanding considerations and utility approval should be reviewed before handover.
