On a single-phase supply, the honest answer is that the 22 kW rating is not available — and what this particular unit does instead is not stated in its listing. The EV-ACT3204PE is specified as a three-phase charger (32 A, 380–400 V), and no single-phase rating or single-phase mode is published for it. So the output question is a confirm-before-you-buy question for EVDANCE and your installer, not a number anyone should quote you from a generic chart.
Key Takeaways
- 22 kW is a three-phase rating; a single-phase supply cannot deliver it.
- The ACT3204PE’s listing publishes no single-phase output or mode — do not let anyone quote you one.
- Get the single-phase answer in writing from EVDANCE and your installer before ordering.
- On a single-phase supply, a roughly 7 kW single-phase charger usually covers overnight charging.
Why 22 kW Is a Three-Phase Number
The rating is arithmetic. Three phases at 32 A and about 400 V between them give roughly 22 kW. One phase at 32 A and about 230 V gives roughly 7.4 kW — that is the ceiling of what a single phase can carry at this current, for any charger, as the explainer on single-phase vs three-phase EV charging sets out. So even in the best case, a single-phase supply turns a “22 kW” purchase into a roughly 7 kW-class outcome — if the unit supports single-phase connection at all.
That last clause is the one that matters, and it is model-specific. Some three-phase chargers are designed to be wired on one phase at reduced output; others are not designed for it, and their control electronics expect a three-phase feed. Which kind the ACT3204PE is cannot be settled from its published specification, because the specification describes the three-phase rating only.
What Is Known, and What Is Not
| Situation | What is established | What to do |
|---|---|---|
| Three-phase supply, car accepts 22 kW | The full 22 kW rating applies | This is the setup the unit is specified for |
| Three-phase supply, car accepts 11 kW | The car sets the pace at about 11 kW | Normal — no fault, no setting to change |
| Single-phase supply | 22 kW is not available; the unit’s single-phase behaviour is not published | Get a written answer from EVDANCE and your installer before ordering |
| Supply type unknown | Nothing about output can be promised yet | Ask an electrician to identify the supply first |
Ask for the answer in writing, and ask it in full: can this unit be connected to a single-phase supply, at what output, and wired how, by a licensed electrician. A one-line “yes” without the output figure is not the answer you need, because the figure is the whole question.
Your Options on a Single-Phase Supply
- Buy for the supply you have. A single-phase charger in the roughly 7 kW class gives you its full, published rating from day one. In the EVDANCE range, the EV-ACS3210E portable charger is a single-phase Type 2 unit at about 7 kW. Overnight, that class of charging covers most daily driving, as the session times in our charging time explainer show.
- Ask about a supply upgrade. Moving a property to three-phase is a network-operator decision with its own application, cost and timetable — an installer conversation, not part of a charger purchase. It only makes sense if you have wider reasons than one wallbox.
- Confirm this unit in writing. If you want the ACT3204E specifically — for its RFID and app control, say — get the single-phase answer from EVDANCE via our contact page before you order, and let your electrician confirm the wiring arrangement it requires.
Frequently Asked Questions
Can I just connect the ACT3204PE to one phase and accept less power?
Do not assume so. Whether this unit may be connected single-phase, and at what output, is a manufacturer and installer question. Connecting a three-phase unit in a way its maker has not approved is how warranties and installations go wrong.
Will a single-phase supply damage the wallbox?
That is exactly the kind of question the written confirmation exists to answer for this model. Until you have it, treat single-phase connection as unapproved rather than as safe or unsafe.
Is about 7 kW enough for home charging?
For most drivers, yes. The U.S. DOT puts Level 2 charging at 10–20 miles of range per hour, and an overnight session at that pace replaces a typical day’s driving with hours to spare.
