Sigenergy has discontinued the 25kW version of its EVDC fast-charging module in Australia and New Zealand. The hardware is not going anywhere. Every EVDC now leaves the factory set to 12.5kW, and the second half of its output comes back as a software licence you buy when you want it. If you already own a 25kW unit, nothing changes.
In short
- The 25kW Sigen EVDC models reached end of marketing for Australia and New Zealand on 9 June 2026, under product change notice EOM2026001. The module itself continues, factory-set to 12.5kW.
- 25kW output is now a paid software licence, activated through the mySigen app or by your installer. No site visit, no new hardware.
- Only units shipped from the change accept the licence. An older 12.5kW EVDC stays a 12.5kW unit.
- The licence raises the ceiling, not the speed on the day. What you draw depends on solar, battery and inverter working together.
- Existing 25kW units keep running at 25kW, with service support for the discontinued codes listed to 9 June 2029.
Model changes on 9 June
Sigenergy's product change notice, dated 20 May 2026, ends marketing and production of four model codes:
| Discontinued model | Product code | Replacement |
|---|---|---|
| SigenStor EVDC 25 7.5S2 | 11080021 | SigenStor EVDC 12 7.5S2 (11080017) |
| SigenStor EVDC 25 10S2 | 11080023 | SigenStor EVDC 12 10S2 (11080024) |
| SigenStor EVDC 25 5S2 | 11080019 | None — 5m cable withdrawn |
| SigenStor EVDC 12 5S2 | 11080015 | None — 5m cable withdrawn |
That leaves two models in the range: the EVDC 12 7.5S2 and the EVDC 12 10S2, with 7.5m and 10m integrated cables. Both are in stock at Sigenergy's warehouse, so this is a tidy-up of the line, not a supply problem. The 5m cable option is gone entirely.
Sigenergy's stated reason is price. A lower factory rating brings down the entry cost of home DC fast charging and vehicle-to-home, and the households that want the full 25kW pay for a licence instead of different hardware.
One box, two ratings
The current datasheet (version 20260609) defines two modes for the same physical module. Standard mode charges and discharges at up to 12.5kW and 40A. The licence lifts that to 25kW and 80A. Everything else is identical between the modes: the 150–1000V operating window, the CCS2 plug, the IP66 rating, the smart air cooling and the bi-directional V2X operation. It is still a module inside the SigenStor stack, paired with the Sigen Energy Controller, not a standalone wallbox.
| Mode | Charging power | DC output current |
|---|---|---|
| Factory standard | 12.5 kW | 40 A |
| After the licence | 25 kW | 80 A |
Two things mark the upgradeable version. The carton carries a green UPGRADABLE label, and the product label reads: “Factory-set ratings limited to: 12.5kW/40A DC output & 42A DC input. Maximum ratings of 25kW/80A DC output & 65A DC input available after software license activation.”
Licence activation
The steps are short enough to do from the couch. In the mySigen app, open Service, then Mall, and buy the SigenStor EVDC 25 kW Fast Charging License. Copy the licence key from your order, activate it, select your system and confirm. The ceiling lifts from 12.5kW to 25kW on the spot. A distributor or installer can do the same on your behalf, and there is no site visit either way.
If your unit is the upgradeable version, the step-by-step with screenshots is in our EVDC upgrade guide.
Will an upgraded unit always charge at 25kW?
No, and Sigenergy says so plainly. The licence raises the ceiling. What you draw under it depends on what the system can supply at that moment: solar, battery and grid, with the grid portion capped at the inverter's rated power.
Sigenergy's own worked example makes the point. A system with a 20kW Energy Controller and two battery packs in fast charging mode reaches 25kW in most conditions. Take the solar to zero on a winter evening and the same system delivers about 22kW, because the grid can only push what the inverter is rated for.
On a single-phase Perth home the arithmetic is tighter again. Reaching the full 25kW leans on solar and battery working alongside the grid, and more battery packs mean more headroom. Charging below 25kW in those conditions is the system behaving as designed, not a fault with the charger or the licence.
Existing owners and new buyers
1. You own a 25kW EVDC
Your unit keeps its rated 25kW. Service support for the discontinued codes runs to 9 June 2029, and the warranty continues on its original terms.
2. You own an older 12.5kW EVDC
The licence does not apply to this version. Discuss the equipment change needed for 25kW before spending anything.
3. You are buying now
Units shipped from 9 June 2026 are the upgradeable version. Check for the green label on the carton.
