Zaptec Go 2 Asphalt Black – 22 kW wallbox with MID-certified meter and 4G

The Zaptec Go 2 is a compact 22 kW wallbox with a Type 2 socket, MID-certified meter and display. Its meter measures in both directions – so it is already prepared for bidirectional charging (V2X). It is always online via Wi-Fi and 4G, switches automatically between 1- and 3-phase charging and, at 239 × 178 mm, is smaller than a sheet of A4. The MID meter makes it the right choice if you need to document the charging electricity for your company car.

The Go 2 comes in three versions:

• Wallbox: the Go 2 on its own – if you already have a Type 2 cable and your house connection is sufficient.
• PV set with Zaptec Sense 65 A: Sense measures in the meter cabinet how much power your home is using right now and continuously adjusts the charging power to match. This enables dynamic load management, dimming under §14a EnWG and, in Germany, solar surplus charging.
• With Type 2 charging cable: the Go 2 together with the Weidmüller Type 2 charging cable, 32 A, 22 kW, 5 m long.

A good fit if …

• you charge a company car at home and want to document the kilowatt hours,
• you want to buy today and charge bidirectionally later without replacing the wallbox,
• you are looking for a small wallbox that can also be mounted outdoors,
• there is no reliable Wi-Fi at your parking space.

Probably not, if …

• you bill charging electricity to others or a third party settles between two parties – then you need an Eichrecht-compliant wallbox,
• you want a cable that is permanently attached at the factory – on the Go 2, however, you can lock your charging cable permanently,
• you are installing in Austria – we do not offer the Go 2 there because of OVE R 37.

What it can do

• Ready for V2X: The MID meter measures energy in both directions. Zaptec intends to enable bidirectional charging (V2G/V2H) via a software update once the standards and rules are clear – your car must support it too.
• ISO 15118 built in: The hardware for communicating with the car in line with ISO 15118 is built in at the factory – you do not need an add-on module. According to Zaptec, ISO 15118-20 comes from 1 January 2027 via a free firmware update.
• Automatic phase switching: The Go 2 switches between 1- and 3-phase charging by itself. That way it also charges cleanly at low power, for example with solar power.
• Precise metering: MID-certified meter; you read the count directly on the display.
• Always online: SIM built in at the factory, plus Wi-Fi – app and updates stay current, even without Wi-Fi at the parking space.
• Smaller than a sheet of A4: 239 × 178 × 73 mm and only 1.6 kg, with a built-in spirit level for installation.
• Your design: The front cover can be swapped; Zaptec offers six colours.
• Open to energy managers: According to Zaptec, the Go 2 can be integrated into third-party systems such as Solarmanager, Powerfox or CleverPV.
• Sharing power: up to three Go 2 per installation.
• Locking the cable permanently: Your external Type 2 charging cable can be locked permanently to the station. It then stays on the wallbox like a fixed cable and is protected against theft.
• Robust: IP54, IK10, −30 to +50 °C, DC residual current protection built in.

Good to know

• Bidirectional charging: Zaptec has not yet named a date for enabling it in Austria and Germany. Your vehicle manufacturer can tell you whether your car supports V2X.
• New installations from 2027: According to Zaptec, the Go 2 is ready from 1 January 2027: the hardware for ISO 15118 is built in at the factory, ISO 15118-20 comes via a free firmware update.
• Load management, §14a and solar: Dynamic load management and dimming under §14a EnWG are available with Zaptec Sense – the PV set includes Sense 65 A. Zaptec currently offers solar surplus charging via Sense in Germany, the Netherlands, Belgium, Switzerland and Luxembourg, for home installations on TN grids.
• Zaptec Sense in the PV set: for house connections up to 65 A, installed in the meter cabinet by your electrician. If Sense loses its internet connection, the wallbox keeps charging at the minimum power of 6 A until Sense is back online.
• 22 kW: Registration with the grid operator and, as a rule, its approval are required. Your electrician takes care of that.
• On site: Circuit breaker and RCD according to local regulations; thanks to the built-in DC residual current detection, a type A RCD is usually sufficient. Installation by an electrician.

Frequently asked questions

Can the Go 2 charge bidirectionally?

The hardware is prepared and the MID meter measures in both directions. According to Zaptec, V2X will be enabled via a software update once the standards and rules are clear. Your car must support bidirectional charging as well.

Is MID enough for billing my employer?

As a rule, yes. Some employers or fleet providers still require Eichrecht – it is best to ask beforehand.

Do I need Wi-Fi?

No. The Go 2 has 4G built in and gets online without Wi-Fi too.

Which charging cable do I need?

A Type 2 cable rated for 32 A so you can use the full 22 kW. The version with charging cable already includes the Weidmüller Type 2 charging cable (5 m, 22 kW).

Where is Zaptec Sense installed?

In the meter cabinet or distribution board, indoors. Your electrician takes care of it. Sense 65 A is only included in the PV set.

How long does a charge take?

At 22 kW, a car with a 60 kWh battery is full in around three hours, provided it can charge at 22 kW AC.
