Eco+ is one charger maker’s name for a solar-aware charging mode: the car charges mainly from surplus rooftop solar, with grid power used only as far as that mode’s rules allow. It is not an industry standard term. Other makers sell the same behaviour under different names — and different behaviour under similar ones — so the name alone tells you very little. What matters is what the mode does with grid power, and that can be decoded on any charger.
Key Takeaways
- Eco+ is one maker’s label for solar-aware charging, not a standard term.
- Decode any eco mode by its grid behaviour: solar-only, solar-preferred with top-up, or timed.
- The manual’s behaviour description outranks the badge; ask what is measured and what happens when the sun dips.
- No EVDANCE listing states an Eco or solar mode — its stated tools are app control, RFID and adjustable current.
Mode Names Are Makers’ Labels, Not Standards
Standards define connectors, communication and safety; they do not name charging modes. Each manufacturer invents its own labels, and the same maker can use one label for slightly different behaviour across its range. Two chargers can both offer an “eco” mode and behave oppositely: one refuses grid power entirely, the other imports freely to hold a minimum rate. Neither is lying — the word was never defined. That is why the manual’s behaviour description, not the badge, is the document to read. The same caution applies across the solar feature family described in our guide to solar panels and EV chargers.
The Three Behaviours Behind the Names
Almost every eco-style mode is one of three behaviours toward grid power:
| Behaviour | What the car gets | What to ask |
|---|---|---|
| Solar-only | Surplus solar only; the session lowers and pauses as surplus falls | Does it measure export, and with what sensor? |
| Solar-preferred with grid top-up | Solar first, then grid power fills in to a set minimum rate so the session never stalls | What is the minimum rate, and can it be changed or switched off? |
| Timed or capped “eco” | A fixed or capped rate on a schedule; no sensing at all | Is anything measured, or is this a timer with a green name? |
The Eco+ name that prompted this article sits in the solar-aware rows on the chargers that use it: surplus-led charging with the maker’s own rules for when grid power may help. On another brand the same slot might be called Eco, Green or Solar — and a mode called Eco+ elsewhere could in principle be a timer. The table, not the name, is the comparison tool.
Four Questions That Decode Any Mode
- Does it measure anything? A sensing mode needs a meter or clamp watching the home’s export. No sensor named, no sensing.
- When the sun dips, what happens? Pause, top up from the grid, or carry on at a set rate — the answer places the mode in the table above.
- Can you override it for a deadline? Most drivers sometimes need a full battery by morning regardless of weather; a good mode lets the deadline win.
- What hardware does it need? If the sensor is an extra, its cost and fitting belong in the comparison too.
Where EVDANCE Fits
No EVDANCE listing states an Eco, Eco+ or solar mode, and this article does not imply an equivalent under another name. The EV-ACT3204E wallbox states RFID and app control; the EV-ACS3210E portable states app control with energy monitoring and adjustable current. Those stated tools support timed, sunny-hours charging and manual rate matching — the third behaviour in the table — and any scheduling scope or solar feature beyond the listing is a written-confirmation question, as with any brand. The full range is on our residential EV charging page.
Frequently Asked Questions
Is Eco+ the same on every charger that uses the name?
No. Mode names belong to individual makers and can vary between their own models. Read the behaviour in the manual for the exact model you are buying.
Is Eco+ a certification or an efficiency rating?
No. It is a mode label chosen by a maker. Efficiency certification is a separate thing — ENERGY STAR, listed in the sources below, is the example.
Do I need solar panels for an eco mode to do anything?
For the solar-aware behaviours, yes — there is no surplus to follow without panels. A timed eco behaviour still works without panels, but then it is scheduling, much like the tariff timing covered in our guide to smart charging and time-of-use tariffs.
