In 2026, there are a whole range of good home wallboxes – names like go-e, Zaptec, Easee, Keba or Huawei keep popping up. For solar system owners, the most important criterion is not the design, but clean PV surplus charging including reliable phase switching. Almost all good boxes charge with 11 kW, which is usually sufficient for a single-family home. Installation is always carried out by a specialist company – that is mandatory and not a question of the model. (As of: July 2026)
Key points in brief
- For PV owners, good surplus charging with reliable phase switching (1- to 3-phase) counts above all.
- 11 kW is almost always sufficient for a single-family home; 22 kW is rarely sensible.
- go-e and Zaptec are considered strong in surplus charging, Keba as particularly robust; Easee is popular, but has a pronounced cloud dependency.
- Anyone who has a closed system (e.g. Huawei) often charges most simply with the wallbox from the same manufacturer.
- Installation is always carried out by the specialist electrical company – regardless of the model.
What is really important when charging with solar power?
Anyone who combines a wallbox with their own solar system should not look at glossy features, but at an inconspicuous ability: surplus charging with clean phase switching. How this basically works is explained in the pillar article Charging an e-car with solar power.
The point: at midday, when there is little sun, the box should charge small surpluses with one phase; switch to three phases at full production. A wallbox that can do this reliably gets significantly more solar power into the car than one that stubbornly stays at three phases and only starts at all from a high surplus. This is exactly where the models differ – not in the casing.
Which wallboxes are relevant in 2026?
| Wallbox | Character (rough classification) |
|---|---|
| go-e | portable, independent of manufacturer, strong in surplus charging |
| Zaptec | well-thought-out phase switching, good for PV charging |
| Keba | industrial robustness, designed for a long lifespan |
| Easee | popular and slim, but pronounced cloud dependency |
| Huawei | native integration in the own solar ecosystem |
Rough classification, As of: July 2026, without a ranking. Models and range of functions change quickly; the currently offered device is decisive.
An honest note about Easee: the box is visually and price-wise attractive, but its control depends heavily on the manufacturer's cloud – for reliable surplus charging, a local, robust control system as possible is an advantage. Anyone who already has a closed system, for example from Huawei, often fares most easily with the wallbox from the same manufacturer, because inverter, battery and box communicate directly with each other. The terms relating to charging technology are clarified in the article Wallbox basics.
Which wallboxes does ecoEn install?
We work independent of manufacturer and select the box according to the system, vehicle and control – not by brand. Currently the most frequently requested and offered by us (without ranking, As of: September 2026):
| Wallbox | Strength | Typical for |
|---|---|---|
| Zaptec Go / Go 2 | Phase switching, load management for multiple charging points | Single-family homes and apartment buildings, underground car parks |
| go-e Charger / Gemini | local control, clean surplus charging | Single-family home with PV, price-conscious |
| KEBA P30 / P40 | robust design, long lifespan | Business, outdoor area |
| Easee Charge Up / Core | slim, popular – cloud-dependent | those who like the app operation and accept the cloud tie-in |
| Fronius Wattpilot · Huawei SCharger | native in the own ecosystem | Systems with Fronius or Huawei inverter |
For on the road or as an interim solution without fixed installation, the Swiss Juice Booster is a mobile alternative. How charging with solar power is specifically planned with us is detailed on the page E-mobility & wallbox.
11 or 22 kW – what power do I need?
For the single-family home, the answer is almost always: 11 kW. That charges an e-car more than fully overnight, and with solar charging, the time on the cable counts anyway, not the maximum power. Why 22 kW is rarely sensible in a private home – and causes expensive additional effort – is covered in detail in the article Wallbox 11 kW or 22 kW.
In short: more power brings hardly anything in everyday life, but costs more and, depending on the grid operator, requires a permit instead of a simple notification. The 11 kW box is the right choice for the vast majority of households.
How do I control the charging – box, app or energy manager?
Surplus charging can be controlled on different levels – directly in the wallbox, via its app or via a higher-level energy manager. Which level leads and when a separate energy manager is worthwhile is covered in the articles Smart charging app and – for the bigger picture of all consumers – Energy managers compared. For your purchase decision, this means: a box that handles surplus charging well out of the box saves an additional manager in the simplest case.
When buying a wallbox, most people look first at the design and the price – we look first at the phase switching. A box that cannot switch down to one phase in the event of a small solar surplus leaves a lot of solar power unused on cloudy days; you only notice this after months on the bill. Experience shows that go-e and Zaptec do this cleanly, Keba is the robust endurance runner. With Easee, we honestly point out the cloud dependency – nice to look at, but for surplus charging we prefer a locally stable control system. And no matter which box: installation is done by the electrician, and with every new system we lay an empty conduit for the future wallbox – that is the cheapest franc you can spend.
Frequently asked questions
Which wallbox is the best for solar power?
The one that masters surplus charging with reliable phase switching. go-e and Zaptec are considered strong here, Keba as particularly robust. Anyone who has a closed system, for example from Huawei, often charges most simply with the box from the same manufacturer. More important than the brand is that the box processes small surpluses cleanly.
Is 11 kW sufficient?
For the single-family home almost always. 11 kW charges an e-car more than fully overnight, and with solar charging, the idle time on the cable counts, not the peak power. 22 kW costs more, needs a permit depending on the grid operator and rarely brings an advantage in everyday life.
Is the Easee wallbox a good choice?
It is popular, slim and price-wise attractive – but has a pronounced dependency on the manufacturer's cloud. For reliable surplus charging, a local, robust control system as possible is an advantage. Whether the Easee is suitable depends on how important stable PV charging is to you compared to design and price.
Does the wallbox have to be installed by a professional?
Yes. The installation of a wallbox is the job of the specialist electrical company and, depending on the power, must be notified to or permitted by the grid operator – that is mandatory and independent of the model. A serious company takes over the installation, notification and correct protection.
Which 11 kW wallbox is the best in 2026?
There is no test winner that is suitable for every system. For charging with solar power, local control, clean phase switching and connection to your inverter or energy manager count – Zaptec Go, go-e and KEBA are strong in this, Easee is popular, but cloud-dependent. Anyone who has a Fronius or Huawei system often fares most easily with the box from the same manufacturer. The overview above classifies the candidates; we make the choice with you according to vehicle, house connection and control.
