EV charger installation in Duncraig.
Big leafy blocks, detached garages down the side, and cable runs that need planning before anyone picks up a drill.
The install
What a Duncraig install actually looks like
Duncraig blocks are big by Perth standards and the houses are mostly 1970s and 1980s brick and tile. Carports and garages are often set back down the side of the block, well away from the meter box at the front. That means the cable run, not the charger, is usually the biggest single variable in the price.
We measure the run properly and size the cable for voltage drop, not just for current. A 30 metre run on undersized cable will make the charger derate and the car will charge slower than it should. Getting this right costs a little more in copper and saves you complaining about it for a decade.
The mature trees are the other Duncraig factor. Tuarts and jacarandas are beautiful and they drop limbs. We keep external runs bracketed high and tight to the wall rather than looping across an open span where a branch can catch them.
Charger picks
Which charger suits a Duncraig home
myenergi Zappi 7kW
Handles partial shade on the roof gracefully, blending solar and grid so the car still charges on a cloudy Duncraig afternoon.

Tesla Wall Connector Gen 3
Neat on a side wall and simple to live with if the household drives a Tesla.

Earth EV Home Charger
Good pick when the charger has to sit on a narrow section of wall beside a carport post.

Solar first
Shade changes the maths here
Duncraig has some of the best tree canopy in the northern suburbs, which is lovely to live under and less lovely for a solar array. Plenty of homes here produce well below what the panel count suggests because a tuart clips the array for two hours each afternoon.
If that is your roof, a pure solar only charging strategy will frustrate you. A charger that can blend a minimum grid rate with whatever the sun is giving you is the better answer, and off peak scheduling covers the rest.
Recent install
A recent Duncraig install
- Location
- Near Warwick Road, Duncraig 6023
- The home
- 1980s brick and tile on a 700sqm block, 5kW solar, single phase, detached garage at the rear.
- The charger
- Zappi 7kW tethered on the garage wall, with a weatherproof isolator alongside.
- Outcome
- 26 metre run in UV conduit along the eaves and down the garage wall. Cable upsized for voltage drop. New RCBO at the board. Full day on site.
What to know before install day in Duncraig
- Long runs need bigger cable. Ask any installer what size they have allowed for and why, and be suspicious of a cheap quote with no run measurement.
- Detached garages sometimes already have a sub main. If it is undersized it will need replacing before an EV circuit can share it.
- Tree cover affects both solar yield and where you can safely run conduit. Worth a look before you settle on a charger position.
Duncraig EV charging questions
My garage is 30 metres from the meter box. Is that a problem?+
Not at all, it just needs the right cable size. We calculate voltage drop over the run and spec accordingly so the charger delivers full output.
Can you run the cable underground?+
Yes, in conduit at the correct depth. It looks cleaner but costs more in trenching and is harder to fault find later, so we usually talk through both options.
Does shade mean solar charging is pointless?+
No. It just means you should not rely on surplus only mode. A blended setting keeps the car charging while still using every free kilowatt hour available.
