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.
Charging Power and Package Summary
Wallbox Quasar is a 7.4kW DC bidirectional charger. Final application depends heavily on the EV model, CHAdeMO compatibility, site electrical supply, protection design and whether V2H / V2G is permitted and supported.
DC Bidirectional Charger
Designed for DC charging and discharging with compatible CHAdeMO electric vehicles.
- Supply, installation, commissioning and training
- Charge output adjustable from 3.7kW to 7.4kW
- Installation available nationwide Malaysia
- myWallbox app and account support
Price and Availability
Pricing, availability and compatibility should be confirmed before purchase because bidirectional charging depends on vehicle support, local approval and site requirements.
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.
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.

Wallbox Quasar Smart Bidirectional EV Charger Features
Smart Charging Features
Bidirectional technology allows compatible EVs to charge and discharge, turning the vehicle battery into a useful energy resource.
A compact smart DC charger designed for home and selected light commercial energy management applications.
Schedule charging sessions, monitor charger status and manage charging through the myWallbox app.
Connect through Wi-Fi, Bluetooth, Ethernet or optional 3G / 4G for smart charger operation.
Bluetooth support allows local charger management even when the parking area has poor internet coverage.
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 2.5mm² x 3C PVC cable with PVC conduit
- Supply, installation, commissioning and training
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.
Suitable Applications
Homes with Compatible EVs
Suitable for early adopters who own a compatible CHAdeMO EV and want smart DC charging.
Vehicle-to-Home Projects
Can support V2H concepts where the vehicle, charger, protection design and regulatory approval allow it.
Vehicle-to-Grid Trials
Suitable for selected pilot projects or utility-supported V2G applications where permitted.
Solar Energy Storage
Potentially useful for storing surplus solar energy in a compatible EV battery.
Home Energy Management
Supports users who want to manage charging, discharging and energy use through a smarter energy strategy.
Demonstration and Pilot Projects
Suitable for innovation projects exploring bidirectional charging, backup energy and EV battery utilisation.
