How the Sigenergy EV chargers work
The AC charger is a wall-mounted unit that connects to your switchboard and plugs into the car with a Type 2 connector or socket. It comes in three sizes: 7 kW for single-phase homes, and 11 or 22 kW for three-phase homes. The 22 kW model adds roughly 130 km of range per hour of charging. All three support solar-surplus charging, dynamic load management, scheduled charging and remote control through the app. Communication is over Wi-Fi, 4G or Ethernet, and the charger uses OCPP 1.6J so it can also work with third-party platforms.
The SigenStor EVDC is a different product: a DC charging module that integrates with a Sigen Energy Controller and the SigenStor battery system. It runs at 12.5 kW and can be upgraded to 25 kW with a licence. Because it is DC, it can also run in reverse (V2X), discharging up to 25 kW from a compatible EV back to the home. At 25 kW it adds about 150 km of range per hour. The connector is CCS2 and the integrated cable is 7.5 or 10 m.

Which Sigenergy charger suits your home
Start with your electrical supply, because that decides the AC options straight away. A single-phase home is limited to the Sigen EVAC 7 (7 kW, 6-32 A). A three-phase home can take the EVAC 11 (11 kW, 6-16 A per phase) or the EVAC 22 (22 kW, 6-32 A per phase). If you want the fastest home AC charging and you have three-phase power, the 22 kW unit is the pick; if you mostly want to soak up solar during the day and top up overnight, the 11 kW is usually plenty.
Then think about how you actually charge. If the car is home most of the day and you have a decent solar system, solar-surplus mode uses PV first and tops up only when there’s spare generation. For example, a 10 kW array on a sunny day will often push 3-6 kW of surplus into the car on top of normal house loads: a 7 kW single-phase charger handles that comfortably. If the car arrives home empty most evenings and needs a fast refill, size up to 11 or 22 kW where possible.
Choose the DC module (SigenStor EVDC) if you are already installing or own a SigenStor system and you want either the fastest charge available in the home (up to 25 kW) or bi-directional V2X so the car can back the house up in a blackout. If you don’t have a SigenStor, the AC charger is the one to look at, since the DC module needs the Sigen Energy Controller to work.

What installation involves
We start with a site visit. We check your switchboard, confirm whether the home is single or three phase, and agree where the charger will go: usually on the garage wall or an external wall close to where you park. For an AC charger, that location decides cable length (the standard cable is 5 m) and whether we need to re-route anything.
For the DC module, we also check that the Sigen Energy Controller and SigenStor battery are in place or planned, since the module can’t work on its own. We lodge the network application with Western Power so the charger can be connected.
On installation day we mount the unit, run the cabling, fit the isolator and connect the charger to the switchboard. We then commission the system, set up solar-surplus charging and load management, and walk you through the app, RFID access (on the DC module) and scheduled charging. One practical tip: keep the charger connected to the internet. Firmware updates, remote diagnostics and the solar-surplus logic all depend on it.
Things to know before you buy
Pros
Solar-surplus charging means the car can run on PV first, so you use more of your own generation.
Three AC sizes to match single- or three-phase supply, and the AC charger can switch between three-phase and single-phase operation.
Dynamic load management shares the available current between the house and the car, so you don’t trip the main.
The 25 kW DC module supports bi-directional V2X, so a compatible EV can discharge back to the home.
Rated IP65 and IK10, so the AC charger can live outside on a wall.
Things to consider
The DC module isn’t a standalone charger. The SigenStor EVDC must be used with a Sigen Energy Controller, so it only makes sense if you already have (or are installing) a SigenStor system.
V2X depends on your car, not just the charger. Even with the 25 kW DC module, the ability to discharge back to the home is limited by what the EV supports. Check your vehicle’s V2H or V2G capability before you commit.
Warranty is 3 years. Both the AC charger and the DC charging module carry a 3-year warranty for systems installed on or after 1 November 2023. Claims must be lodged within 30 days of the failure date, so register the install details and keep them somewhere easy to find.
Some documentation isn’t published. Sigenergy doesn’t publish AC cable length options other than the standard 5 m, and doesn’t publish a CEC or AS/NZS certification statement for the AC charger or an Australian V2G/V2H grid-approval status for the DC module. We confirm what’s approved for your network at quote stage.
22 kW needs three-phase power. The fastest AC model (22 kW) and the 11 kW model both need three-phase supply. A single-phase home is limited to the 7 kW unit.
Sigenergy EV charger questions Perth homeowners ask
Does Sigenergy have an EV charger?
Yes. There is a wall-mounted AC charger in three sizes (7, 11 and 22 kW), and a DC charging module that pairs with a Sigen Energy Controller as part of the SigenStor system. The DC module runs at 12.5 kW and can be upgraded to 25 kW.
Is the Sigenergy EV charger any good?
Where it stands out is working as one system with Sigenergy solar and battery, so the car can charge from PV first. We’d match the model to your supply before anything else.
Which EV chargers are OCPP compatible?
The Sigen EV AC charger supports OCPP 1.6J ED 2, so it can be managed by third-party charging platforms if you need that. It also communicates over Wi-Fi, 4G or Ethernet.
Do I need a special charger for an electric car?
You can plug an EV into a standard power point, but it is slow. A dedicated home charger adds speed, safety features, scheduling and solar-surplus charging. The Sigen EVAC 22 can add about 130 km of range in an hour; the 25 kW DC module can add about 150 km.
Can a normal electrician install an EV charger?
An EV charger must be installed by a licensed electrician, and in WA the work also has to be approved by the local network operator. We handle the switchboard check, the network application, the install and the commissioning as one job.
What is the lifespan of a home EV charger?
Sigenergy publishes a 3-year warranty on both the AC charger and the DC charging module for systems installed on or after 1 November 2023. In practice a well-installed, weather-protected unit lasts well beyond the warranty period.
