The EV-ACT3204PE‘s listing does not state a solar or surplus-following mode, so this wallbox does not chase your roof’s output by itself. What a three-phase solar PV system genuinely changes is timing: charge while the array is generating, and the grid covers whatever the roof cannot, second by second. Surplus-following is a feature to get confirmed in writing before you rely on it.
Key Takeaways
- No solar or surplus-following mode is stated for the EV-ACT3204PE — do not buy it as one.
- On a grid-tied system every session is a roof-and-grid blend; timing is how you raise the solar share.
- A three-phase session cannot run below roughly 4 kW, so fine matching belongs to smaller, adjustable chargers.
- Confirm any solar mode, meter link and app scheduling scope in writing before relying on them.
What “Charging From Solar” Means on a Grid-Tied System
There is no separate solar wire to the charger. Panels feed the property, the inverter works at the switchboard, and the wallbox draws from the same supply as every other load. At any moment a session’s energy is a blend — some from the roof, the rest from the grid. Our guide to solar panels and EV chargers covers the wider picture.
At full rate the ACT3204PE draws up to 22 kW. Unless the array is very large, that is more than the roof is producing at most moments, so a full-rate daytime session is always partly a grid session. That is normal, not a fault: the session does not stall when a cloud crosses.
The Three-Phase Floor
One piece of arithmetic shapes every three-phase solar plan: a session has a minimum rate, set by the car’s lowest accepted current per phase. Labelled arithmetic at 400 V:
| Supply | Lowest session power (arithmetic) | What it means for solar matching |
|---|---|---|
| Single-phase, 6 A | About 1.4 kW (230 V × 6 A) | A session can sip a small surplus |
| Three-phase, 6 A per phase | About 4.2 kW (√3 × 400 V × 6 A) | The session cannot go below roughly 4 kW while it runs — on a modest array, much of it is grid-blended |
That floor does not make the wallbox a bad solar partner; it makes it a blunt one. Where fine-grained matching matters more than speed, the finer tool in this range is a single-phase adjustable portable such as the EV-ACS3210E, whose current adjusts in steps. The wallbox’s case is cars home in the day that want real energy in the sunny hours.
Timing Is the Tool This Wallbox Gives You
- Be plugged in for the sunny hours — the car home and connected while the array generates.
- Use the car’s own charge timer. Many cars can be told when to charge; the wallbox supplies, the car decides the window, regardless of charger features.
- App scheduling — as far as the app offers it. The listing states app control; what scheduling the supplied app provides is a scope question to confirm before building a routine on it. How scheduling interacts with tariffs is covered in our guide to smart charging and time-of-use tariffs.
- Surplus-following is not on this list. It needs a meter link watching the home’s export, and is not stated for this unit — a written confirmation, not an assumption.
Questions to Settle Before You Buy for Solar
- Is any solar, surplus or meter-linked mode offered for this unit? Get the answer in writing — the listing states none.
- What scheduling does the supplied app actually provide?
- What does your installer say about the whole system — array, inverter and wallbox — as one design? Inverter settings are the installer’s area; this article states none.
The unit itself, from its listing: the EVDANCE EV-ACT3204PE is a hardwired 22 kW three-phase wallbox (380–400 V, 32 A), Type 2 in cable or socket form, with RFID and app control, an IP66 rating and CE marking. Paired with three-phase PV it is a fast daytime charger whose solar share you manage by timing.
Frequently Asked Questions
Does the EV-ACT3204PE follow solar surplus automatically?
Not on anything its listing states: automatic following needs a meter link watching your export, and no such mode is listed. If a seller claims otherwise, ask for it in writing.
Can it charge the car at night from my panels?
No. Panels generate nothing at night and the wallbox stores nothing. Night charging on solar energy means a home battery charged during the day — a separate purchase.
Do the inverter and the wallbox need to be the same brand?
They never connect directly — both work through the property’s switchboard. What matters is that the whole system is designed together, which is your installer’s job; brand-matching is not a requirement stated anywhere in this unit’s listing.
