ZEVpoint DUOS 11kW vs 22kW EV Charger: Complete Guide for Home & Commercial Charging

Choosing the right EV charger is not only about selecting the highest charging power. Your vehicle’s onboard AC charger, the electrical supply available at the installation site, and how the charger will be used all play an important role. For EV owners, offices, hotels, apartment societies and businesses looking for a smart three-phase AC charging solution, the ZEVpoint DUOS offers an interesting advantage: the same charger can be used for both home and commercial charging.

Available in 11 kW and 22 kW three-phase variants, the ZEVpoint DUOS combines Type 2 EV charging with OCPP connectivity and dedicated Home and Commercial modes.

What Is the ZEVpoint DUOS EV Charger?

The ZEVpoint DUOS is a wall-mounted smart EV charger designed for both personal and managed charging applications. Its key differentiator is the Home–Commercial Toggle Switch. In a residential setup, the charger can be used for convenient personal EV charging.

When commercial functionality is required, the charger can operate as an OCPP-enabled charging point connected to a compatible charging management system. This makes DUOS suitable for installations where charging requirements may evolve over time—for example, a personal parking space that later requires controlled access, an office charger shared between employees, or an apartment charging point that needs usage management.

ZEVpoint currently lists DUOS in 7.5 kW, 11 kW and 22 kW configurations, with the 11 kW and 22 kW models designed for three-phase installations.

Key Features of the ZEVpoint DUOS

Home and Commercial Charging ModesDUOS allows users to move between home and commercial charging requirements without replacing the charger.

For home charging, this provides a straightforward charging experience. For commercial applications, the charger can be integrated into a managed charging setup where operators may need greater control over charger access and usage.

OCPP 1.6 Support

The DUOS range supports OCPP 1.6, making it suitable for integration with compatible EV charging management platforms.

For businesses, offices, hotels, fleet parking areas and apartment societies, an OCPP EV charger can enable functions such as charger monitoring, session management, usage tracking and controlled access, depending on the capabilities of the connected charging management system.

Type 2 EV Connector

Both the DUOS 11 kW and DUOS 22 kW use a Type 2 connector based on IEC 62196-2.

Type 2 is widely used for AC charging by electric cars in India, making DUOS suitable for a broad range of Type 2 compatible EVs.

The actual charging rate will always depend on the maximum AC charging power supported by the vehicle.

Three-Phase EV Charging

Both the 11 kW and 22 kW DUOS variants operate on a 400 V three-phase electrical supply.

Three-phase charging makes these chargers particularly relevant for homes with suitable three-phase connections as well as offices, hotels, commercial properties, apartment complexes and other locations with higher connected electrical loads.

Designed for Indoor and Outdoor Installations

The DUOS operating temperature range is specified from -35°C to +60°C. The charger also incorporates safety-related features including overheating protection, short-circuit protection, grounding protection, water and dust resistance, and an emergency stop switch.

ZEVpoint DUOS 11kW vs 22kW: What's the Difference?

The biggest difference between the two chargers is their maximum AC output.

These specifications are based on ZEVpoint's current DUOS 11 product listing.

Who Should Consider an 11kW EV Charger?

An 11 kW EV charger can be suitable for homeowners who have a three-phase electrical connection and a vehicle capable of accepting higher three-phase AC charging speeds.

It can also work well for:

• Residential EV charging
• Apartment parking
• Small offices
• Employee EV charging
• Hotels and guest parking
• Small commercial parking areas
• Fleet vehicles with sufficient overnight or dwell time

For many EV owners, 11 kW provides a useful balance between charging speed and electrical infrastructure requirements.

ZEVpoint DUOS 22 kW EV Charger

The DUOS 22 increases the maximum AC charging output to 22 kW and supports up to 32A.

Key specifications include:

• Maximum output: 22 kW
• Input: 400 V three phase
• Current range: 6A–32A
• Connector: Type 2
• Cable length: 20 feet
• OCPP support
• Home and Commercial modes
• Wall-mounted installation

Who Should Consider a 22kW EV Charger?

A 22 kW EV charger is particularly relevant where higher AC charging capacity is required and both the vehicle and electrical infrastructure can support it.

Typical applications can include:

• Commercial EV charging
• Office parking
• Apartment societies
• Hotels and resorts
• Dealerships
• Fleet parking
• Business premises
• Destination charging locations
• High-usage private parking

Which Is Better for Home EV Charging: 11kW or 22kW?

For home EV charging, the right choice depends primarily on your car and electrical connection rather than simply choosing the charger with the highest output.

An 11 kW three-phase EV charger can be a practical choice when your car supports 11 kW AC charging and your daily charging requirement can comfortably be completed within your normal parking period.

A 22 kW home EV charger becomes more relevant when your EV can make use of higher AC charging power, your property has sufficient electrical capacity, or you want greater headroom for future vehicles.

Before installing either option, the available electrical load should be checked by a qualified electrician or EV charging installation professional.

Which Is Better for Commercial EV Charging?

Commercial charging has different requirements from typical home charging.

Businesses may need to consider:

• Multiple users
• Charger access control
• Energy consumption monitoring
• Charging session records
• Centralized charger management
• Billing or monetization
• Remote charger monitoring
• Future expansion

This is where an OCPP-enabled EV charger such as the ZEVpoint DUOS can be useful.

Because DUOS combines Home and Commercial operating modes with OCPP functionality, it can be deployed in environments ranging from private parking to managed commercial charging infrastructure.

For installations where vehicles have shorter dwell times or higher AC charging capability, the 22 kW variant offers greater available charging capacity. Where vehicles remain parked for longer periods, such as overnight apartment parking or office parking, 11 kW may already provide sufficient charging capacity.

Can the ZEVpoint DUOS Be Used in Apartment Societies?

Yes, DUOS is particularly relevant for apartment and residential society EV charging because these installations often require more management than a standard private home charger.

An apartment EV charging setup may need to identify users, monitor energy consumption, manage charger access and connect multiple charging points to a central management system.

OCPP connectivity provides a foundation for these types of managed charging environments when used with compatible charging software.

This makes DUOS suitable for:

• Individual apartment EV parking
• Shared residential parking
• Resident EV charging
• Managed society charging stations
• Visitor EV charging
• Paid or controlled charging setups

Installation Requirements for an 11kW or 22kW EV Charger

High-power three-phase EV chargers should always be installed using a properly designed dedicated electrical circuit.

Before installation, the electrical system should be evaluated for:

• Three-phase power availability
• Sanctioned electrical load
• Suitable cable sizing
• Cable run length
• Appropriate circuit protection
• Surge protection
• Proper earthing
• Distribution board capacity
• Voltage stability

Cable size and electrical protection requirements should be determined according to the charger model, cable distance, site conditions and applicable electrical standards rather than using one fixed cable size for every installation.

A qualified electrician or EV charger installation professional should assess the site before commissioning the charger.

Home EV Charger or Commercial EV Charger? DUOS Can Do Both

Traditionally, buyers may choose a simple home EV charger for residential use and a separate OCPP charger when access control or commercial charging functionality is required.

DUOS is designed to bridge those two requirements.

A homeowner can use it as a wall-mounted home EV charger, while businesses, apartment societies and commercial operators can use its OCPP capabilities as part of a managed EV charging setup.

This can be particularly useful when the requirement may change in the future.
