EV chargers compared – the best wallboxes for solar and smart charging
A wallbox is more than a socket on the wall. To charge your car on surplus solar or in the cheapest hours of a dynamic tariff, it has to be controllable from outside. We compared 28 popular home chargers on price, phase switching, connectivity and OCPP, and show which ones work with Zerofy natively or through the open OCPP standard.
Compare chargers What to look forHow Zerofy connects to your charger
Zerofy runs in the cloud, so there is no energy manager box to install. It talks to your charger in one of two ways. A third group of chargers cannot be steered from outside at all.
Native integration
The brand has its own entry in the Zerofy app. Easee, go-e and Zaptec connect through the manufacturer's cloud API, so you just log in with your account. Wallbox, Fronius Wattpilot, Huawei SCharger and BENY connect via OCPP, and the app shows you the exact settings for your charger.
Cloud API: Easee, go-e, Zaptec · OCPP: Wallbox, Fronius Wattpilot, Huawei SCharger, BENY
Show native chargersAny charger with OCPP
If your charger speaks OCPP 1.6J and lets you (or your installer) enter your own backend address, you can add it as a generic OCPP charger. Zerofy then starts and stops charging and sets the charging current, just like with a native integration.

Show OCPP chargersClosed systems
Some popular chargers have neither an open cloud API nor an OCPP backend you can change. They may still charge on solar within their own manufacturer's ecosystem, but no independent energy manager can steer them.
Tesla Wall Connector, Ohme, Heidelberg Energy Control and others
Show closed chargersWhat is OCPP?
OCPP (Open Charge Point Protocol) is an open standard from the Open Charge Alliance that lets a charger talk to a central management system, the so-called backend or CSMS. Public charging networks have used it for years, and most modern home wallboxes support it too, usually as version 1.6J and increasingly 2.0.1.
The charger opens the connection itself, so there is no port forwarding or local network setup. Through OCPP, the backend can start and stop sessions, set the charging current and read meter values.
Connecting an OCPP charger to Zerofy
- In the Zerofy app, add an EV charger, pick your brand or the generic OCPP charger, and copy the OCPP address shown.
- Open your charger's app or web interface (sometimes the installer menu) and paste the address as the OCPP server or backend URL.
- The charger reconnects within a few minutes and appears in Zerofy, ready for Autopilot.
Most chargers accept only one OCPP backend at a time. If your employer or a charging card provider already manages your wallbox via OCPP, check with them before switching. Some manufacturers also limit their own app while OCPP is active.
Six things a wallbox needs for solar and smart charging
For simple overnight charging almost any wallbox will do. To follow your solar production or a dynamic electricity price, these features make the difference.
An open interface
An energy manager has to be able to control the charger. That works through a cloud API, through OCPP with a backend address you can change, or locally via Modbus or EEBus. Chargers without any network connection can only be switched on and off with an external contactor.
Tip: Check that OCPP is available on the home model, not only the business version, and that you can enter your own backend.
Adjustable charging current
Solar surplus changes from minute to minute. A good wallbox adjusts the charging current in steps of 1 A between 6 A and 16 A or 32 A, so charging can follow the sun instead of just switching on and off.
Tip: Make sure the current can be changed during a session, not only set once at installation.
1/3-phase switching
Cars need at least 6 A to charge. On three phases that is about 4.1 kW, so a three-phase-only charger needs more than 4 kW of surplus before it can start. Switching to one phase lowers the threshold to about 1.4 kW, which makes a big difference in spring, autumn and winter.
Tip: Especially useful with smaller solar systems. Zerofy switches phases on Easee, go-e and Zaptec.
11 kW is usually enough
Most electric cars charge on AC with at most 11 kW, and only a few accept 22 kW. An 11 kW wallbox fills a typical battery overnight, and in several countries 22 kW needs approval from the grid operator.
Tip: Buy 22 kW only if your car supports it and your grid connection allows it.
Calibrated meter (MID)
A MID-certified meter records exactly how much energy went into the car. That matters if your employer reimburses home charging of a company car, or for emission credits (ERE) in the Netherlands. Billing third parties in Germany needs an Eichrecht-compliant charger, which is stricter than MID.
Tip: For a private car, the charger's own meter and the charging history in Zerofy are enough.
Safe installation
Every wallbox needs a residual current device. Chargers with built-in 6 mA DC fault detection only need a standard type A RCD instead of a much more expensive type B. Always have a qualified electrician install the charger and notify the grid operator.
Tip: In Belgium and Norway many homes have a 3×230 V grid without neutral. Check that the charger supports it.
28 home EV chargers compared
Chargers with a native Zerofy integration come first, followed by popular wallboxes that work with Zerofy through OCPP and a few closed systems. Filter by connection type or search by name.
Easee Charge Max
from €595
The Norwegian bestseller in its 2026 EU version: a compact 22 kW box with built-in LTE, so it stays online without Wi-Fi, plus a MID meter and an Eichrecht variant. It also works on 3×230 V IT grids. Zerofy logs in to your Easee account and controls current and phases through the Easee cloud. Its predecessor Charge Up leaves the EU market at the end of 2026 and is supported in exactly the same way.

What to know in your country
Rules for installation, grid fees and feed-in differ a lot across Europe, and they decide how much solar and smart charging is worth.
| Country | What matters for your wallbox |
|---|---|
| Germany | §14a EnWG: notify 11 kW, get approval for 22 kWEvery wallbox must be notified to the grid operator, and above 12 kVA (so 22 kW) it needs approval. Wallboxes over 4.2 kW installed since 2024 must be controllable by the grid operator, who may reduce them to no less than 4.2 kW; in return you pay lower grid fees. Since 2025 every supplier must offer a dynamic tariff. There is no federal subsidy for wallboxes at single-family homes. |
| Austria | Notify from 3.68 kVA, check your grid operatorChargers from 3.68 kVA must be notified, and above about 12 kW the grid operator may cap or refuse the connection. The federal subsidy for private wallboxes closed in spring 2026 when its budget ran out; some states still pay. Smart meters have a customer interface that shows your live solar surplus. |
| Switzerland | Approval above 11 kW, low summer feed-in pricesYour electrician files a connection request and an installation notice, and above 11 kW the grid operator must approve. Since 2026 solar feed-in is paid at the quarterly market reference price, which is low in summer, so charging from your own roof pays off. vZEV and local electricity communities (LEG) let you share solar with neighbours. |
| Netherlands | Net metering ends on 1 January 2027Once the salderingsregeling ends, exported solar earns much less, so charging your car on your own surplus becomes far more valuable. 3×25 A is the standard connection, and a heavier one can mean a long wait in congested areas. About 8% of households already have a dynamic contract. Since 2026 home charging can earn ERE emission credits, which requires a MID meter. |
| Belgium | Capacity tariff in Flanders, many 3×230 V gridsIn Flanders your grid fee depends on your highest quarter-hour peak each month, so spreading charging over time saves money. Many older homes have a 3×230 V grid without neutral, where most cars charge on one phase only (up to 7.4 kW); Easee and Zaptec support these grids. Since 2026 Wallonia has a daytime off-peak window from 11:00 to 17:00. |
| Poland | Net-billing: self-consumption pays mostExported solar is credited at its market value, for newer prosumers at hourly prices, so charging your car on your own surplus is worth more than feeding it in. There is no national wallbox subsidy in 2026. Suppliers with at least 200,000 customers must offer dynamic tariffs, which need a remotely read meter. |
| Sweden | 50% tax deduction for a home chargerLabour and materials for a fixed home charge point qualify for the green technology deduction (grön teknik) of 50%, up to SEK 50,000 per person per year across all green technology items. |
| Norway | Mostly 230 V IT gridsMost Norwegian homes have a 230 V IT grid, where car makers advise single-phase charging (up to 7.4 kW). Pick a charger approved for IT grids, such as Easee or Zaptec. |
| Estonia | Spot prices are part of daily lifeAlmost every household has a remotely read meter, and exchange-price contracts are widely offered, so charging in the cheapest hours with Zerofy's Smart mode pays off directly. |
Solar and smart charging without extra hardware
Zerofy is a cloud energy manager, so there is no box to install in your fuse cabinet. It combines your charger with your inverter, battery, smart meter and car, and Autopilot decides when and how fast to charge.
- Charge on surplus solar, with automatic phase switching on Easee, go-e and Zaptec
- Charge in the cheapest hours of your dynamic tariff with Smart mode
- One app for 7 native charger brands, any open OCPP charger and over 80 other device brands
Frequently asked questions
Which EV chargers work with Zerofy?
Zerofy has native integrations for Easee, go-e and Zaptec (cloud API) and guided OCPP setups for Wallbox, Fronius Wattpilot, Huawei SCharger and BENY. On top of that, any charger that speaks OCPP 1.6J and lets you enter your own backend address can be added as a generic OCPP charger, for example Alfen, ABB, KEBA, Elli, MENNEKES, Sungrow, SolaX, Growatt, Autel and myenergi zappi. If your charger is closed, Zerofy can often steer charging through the car instead, for many car brands including Tesla.
What is the difference between a native integration and OCPP?
With a native cloud integration you simply log in with your manufacturer account, and Zerofy reads the charger and controls it through the manufacturer's cloud, including phase switching on Easee, go-e and Zaptec. With OCPP the charger connects directly to Zerofy. That also applies to Wallbox, Fronius Wattpilot, Huawei SCharger and BENY: they have their own entry in the app, but the connection itself runs via OCPP. Zerofy can then start and stop charging, set the current and read the meter, but phase switching is not available over OCPP. For solar charging on three phases this means a start threshold of about 4.1 kW.
Can I use Zerofy and my employer's charging backend at the same time?
Usually not. Most wallboxes accept only one OCPP backend, and the backend that bills your employer is often configured by a fleet or charging card provider. Ask them before you change the backend address. With a native cloud integration (Easee, go-e, Zaptec) this conflict does not arise, because Zerofy uses the manufacturer's cloud rather than OCPP.
Do I need automatic 1/3-phase switching?
It depends on your solar system. A car needs at least 6 A per phase to charge: on one phase that is about 1.4 kW, on three phases about 4.1 kW. With 3-phase-only charging, a 6 kWp system rarely produces enough surplus outside summer. With phase switching the car starts charging from about 1.4 kW of surplus and moves to three phases when the sun is strong. Note that some cars pause briefly or need a few seconds to adapt when phases change.
Should I buy an 11 kW or a 22 kW wallbox?
For most homes 11 kW is the right choice. Most electric cars charge on AC with at most 11 kW, an 11 kW charger refills about 50 km of range per hour, and in Germany, Austria and Switzerland 22 kW needs approval from the grid operator. A 22 kW charger makes sense only if your car supports it and your connection allows it. You can usually limit a 22 kW charger to 11 kW.
Do I need a MID-certified meter?
For a private car, no. In Germany, employers have to reimburse home charging of company cars per kWh from 2026, and a separate meter is required for that; a MID meter is the safe choice, but check with your employer. In the Netherlands, earning ERE emission credits for home charging requires a MID meter. Billing other people, for example tenants, in Germany needs an Eichrecht-compliant charger.
My charger is not in this list. How do I know if it works with Zerofy?
Look in the manual or the charger app for a setting called OCPP, OCPP server, backend, central system or CSMS. If you can enter your own address there, your charger very likely works with Zerofy as a generic OCPP charger. If the backend can only be chosen from a fixed list or only through the manufacturer's support, ask them to add Zerofy's address. You can try it for free in the Zerofy app.
Which charger should I buy for solar charging?
If you want the simplest setup with phase switching: Easee, go-e or Zaptec, which Zerofy controls natively through the cloud. If you already have a Fronius, Huawei or Sungrow inverter, the matching wallbox fits nicely into that system and still works with Zerofy via OCPP. In Belgium or Norway on a 3×230 V grid, Easee and Zaptec are the safe choices. On a tight budget, pick any wallbox with open OCPP, such as Autel or Growatt, and avoid closed systems if you want to stay independent of one manufacturer.
