Compleo eBOX versions compared: which one is right for you?
Three questions decide which Compleo eBOX is right for you: do you bill kilowatt hours to different users? Do you need to provide proof of your own kilowatt hours? And do you want a fixed cable or a socket? Technically, all eBOXes are very similar – 22 kW, built-in DC residual current protection, open interfaces. The difference lies in the meter, the authorisation and the connectivity. Here you will find the right version in just a few minutes.
Key points at a glance
- Only your own car, no proof required: eBOX smart socket or eBOX professional cable.
- Bill a company car directly with your employer: eBOX professional cable MID. In Austria, the EKA version is required if billing is handled by a service provider.
- Bill kWh to different users – tenants, guests, customers, employees with private cars: eBOX professional socket EKA or cable EKA.
- All Compleo eBOXes purchased from Ampion or e-leiwand have been updated to at least firmware 2.6 and function-tested.

Three questions that decide
1. Do you bill kilowatt hours to different users?
As soon as you bill the kWh charged to different users – for example to tenants, co-owners, hotel guests, customers or employees with their private cars – a wallbox compliant with Austrian and German calibration law (Eichrecht) is mandatory in Austria as well as in Germany. In Austria, the same applies if a service provider bills the charging electricity to a third party – for example, reimbursement by your employer of the kWh charged at home. In Germany, MID is usually sufficient for company car reimbursement; some employers or service providers nevertheless require Eichrecht compliance. For the eBOX, the Eichrecht-compliant version is called EKA. That settles the decision – the only remaining question is cable or socket.
2. Do you need to provide proof of your own kilowatt hours?
If you charge a company car at home and bill the electricity to your employer, an MID meter is generally sufficient – as long as you bill the kWh directly with your employer. The right version is the eBOX professional cable MID. If, in Austria, a service provider handles the reimbursement and passes the costs on to your employer, you need the EKA version. It is best to ask beforehand how your employer handles billing.
3. Fixed cable or socket?
If you neither need to bill nor provide proof, it is mainly a question of convenience and features. With a fixed cable, you simply plug in; with a socket, you use your own charging cable. More on this below.
All versions at a glance
| Version | Connection | Meter | Ideal for |
|---|---|---|---|
| eBOX smart socket | Type 2 socket | internal, not certified | your own car at home, affordable entry-level option |
| eBOX professional cable | 6.5 m cable | internal, not certified | your own car at home, with professional features |
| eBOX professional cable MID | 6.5 m cable | MID | company car, own company fleet |
| eBOX professional socket EKA | Type 2 socket | compliant with Austrian and German calibration law (Eichrecht) | kWh billing to different users with their own cable |
| eBOX professional cable EKA | 6.5 m cable | compliant with Austrian and German calibration law (Eichrecht) | kWh billing to different users, e.g. hotels and restaurants |
eBOX smart or eBOX professional?
The eBOX smart is the slim wallbox for private parking spaces. It charges at up to 22 kW, speaks OCPP and Modbus TCP and can be controlled via app. You decide who may charge in an app such as Monta or eCarUp – the app then takes over the role of the charging card.
The eBOX professional also offers:
- RFID reader – charging by card, even without a smartphone.
- Mobile connectivity with its own mini SIM (anySIM) – for parking spaces without LAN or Wi-Fi.
- Plug & Charge according to ISO 15118-2 – the car registers itself when plugged in (from firmware 3.x, with a suitable backend).
- Load distribution between several eBOXes on the same connection, without additional hardware.
- Versions with an MID meter or metering compliant with Austrian and German calibration law (Eichrecht).
Rule of thumb: if only your own car charges and the app is enough for you, the eBOX smart will do. As soon as several people charge, cards are involved, there is no network at the parking space or billing is required, the eBOX professional is the right choice.
Meter: internal, MID or compliant with Austrian and German calibration law (Eichrecht)
| Meter | What it does | What it is sufficient for |
|---|---|---|
| internal | shows you consumption, not certified | your own overview |
| MID | verified, kWh-accurate measurement | proof of your own costs, e.g. company car reimbursement directly with your employer |
| compliant with Austrian and German calibration law (EKA) | MID measurement plus signed meter readings | kWh billing to different users or – in Austria – via a billing service provider |
Important: MID is not the same as Eichrecht compliance. An MID meter is sufficient if you are providing proof of your own costs. As soon as you bill kWh to different users or, in Austria, a service provider bills the charging electricity to a third party – such as your employer – the EKA version is mandatory. For the actual billing, you also need a backend that processes the signed meter readings.
The eBOX smart can be extended with an MID meter using the eSMARTMETER. This does not make it compliant with Austrian and German calibration law (Eichrecht).
Fixed cable or socket?
- Fixed cable (cable): plug in and charge without getting the cable out of the boot. The 6.5 m reaches whether you park forwards or backwards. Ideal if the same cars always charge or if guests should not have to bring a cable.
- Socket (socket): every car charges with its own Type 2 cable, and a defective cable is quickly replaced. Ideal if different vehicles charge or the wallbox is installed in a heavily used location. For 22 kW, you need a 32 A cable.
The versions in detail
eBOX smart socket
Right for you if you already have a Type 2 charging cable, only your own car charges and you are looking for an affordable, robust wallbox for your private parking space.
Less suitable if you need to provide proof of or bill kilowatt hours, or several people should charge by card.
Go to the eBOX smart socket
eBOX professional cable
Right for you if you charge your own car at home, do not need to provide proof of kilowatt hours and still want RFID, mobile connectivity, Plug & Charge or several charging points on the same connection.
Less suitable if you bill a company car (then MID) or bill kWh to different users (then EKA).
Go to the eBOX professional cable
eBOX professional cable MID
Right for you if you charge a company car at home and bill the kilowatt hours with your employer, or charge company vehicles at your own site. The MID meter is already clipped into the eCLICK module, and RFID assigns every charging session.
Less suitable if you bill kWh to different users or, in Austria, a service provider handles the reimbursement and passes it on to your employer – then you need the EKA version.
Go to the eBOX professional cable MID
eBOX professional socket EKA
Right for you if you bill kWh to different users – tenants, co-owners, guests, customers or employees with private cars – and different vehicles charge at your charging point with their own cable.
Less suitable if you are only providing proof of your own costs (then MID) or your guests arrive without a cable (then cable EKA).
Go to the eBOX professional socket EKA
eBOX professional cable EKA
Right for you if you bill kWh to different users and they should simply be able to plug in – typical for hotels, restaurants, company and guest car parks.
Less suitable if different vehicles should charge with their own cable – then the socket EKA is more flexible.

What all eBOXes have in common
- Up to 22 kW, single- to three-phase, adjustable in steps.
- Built-in DC residual current detection – a Type A RCD in the distribution board is sufficient.
- Open interfaces: OCPP 1.6 for apps and backends such as Monta or eCarUp, Modbus TCP for energy management such as Loxone.
- PV surplus charging with a Modbus TCP smart meter such as the Shelly Pro 3EM.
- Robust: IP55, IK10, operation from −30 to +50 °C, LED light ring.
- eCLICK system: the electrician mounts the connection plate, and the eBOX is simply clipped in.
- OVE R37: the eBOX has a currently valid manufacturer's declaration according to OVE R37 and can therefore be connected to the grid in Austria.
- Setup in the browser via the web interface – explained step by step in Setting up the Compleo eBOX without an app.
You can read how to control any eBOX free of charge via app in Control the Compleo eBOX with an app.
Conclusion
Choosing the right eBOX is easier than the range of models suggests. If you bill kWh to different users or, in Austria, billing runs via a service provider, there is no way around the EKA version. If you bill your company car directly with your employer, choose the MID version. If only your own car charges, decide based on convenience: the eBOX smart as an affordable entry-level option with app control, the eBOX professional if you need RFID, mobile connectivity or several charging points.
Frequently asked questions
Can I upgrade an eBOX smart later?
You can retrofit an MID meter with the eSMARTMETER. This does not make the eBOX smart compliant with Austrian and German calibration law (Eichrecht) or add an RFID reader – for that, you need an eBOX professional.
Do I need approval for 22 kW?
22 kW must be registered with the grid operator and generally requires its consent; in Germany, anything above 12 kW requires approval. Your electrician will take care of this. Many cars only charge at 11 kW anyway – more on this in 11 kW or 22 kW wallbox – which is worthwhile?
May I install the eBOX in Austria?
Yes. There is a currently valid manufacturer's declaration according to OVE R37 for the eBOX, which grid operators check when connecting. The manufacturer's declaration is valid until 14/12/2026 – so plan installation and registration with the grid operator in good time. We explain what is behind R37 in OVE R 37 explained.
My employer bills via a service provider. Is MID sufficient?
In Austria, no. If a service provider reimburses you for the kWh charged at home and passes the costs on to your employer, the charging electricity is billed to a third party – this requires a wallbox compliant with Austrian and German calibration law (Eichrecht), i.e. the eBOX professional EKA. In Germany, MID is usually sufficient for company car reimbursement; some employers or service providers nevertheless require Eichrecht compliance. It is best to ask beforehand how your employer handles billing.
Do I need a SIM card?
Only with the eBOX professional and only if there is no LAN or Wi-Fi available at the parking space.
Can I operate several eBOXes on the same house connection?
Yes. Several eBOX professional units distribute the power among themselves on the local network, and with a smart meter also dynamically based on actual consumption.
Who handles billing with the EKA version?
A backend that processes the signed meter readings. We offer Smartfuelpass from Ultima Payments or Vaylens for this – write to us at onlinesales@ampion.at.
I am not sure which version I need.
