EV charger installation, Castle Hill.

A standard 7kW single-phase install in a Castle Hill home on a modern switchboard typically takes 3–4 hours — site assessment, cabling run, mounting, commissioning, and app pairing. If the run to a detached garage is 15–25 metres, allow for a full half-day, as conduit routing through the roof cavity or along eaves adds time depending on the path. Solar-integrated installs with eco mode configuration add approximately 30–45 minutes for inverter assessment and charger commissioning. We confirm the expected duration when we quote. There are no surprises on the day.

Castle Hill is in the Endeavour Energy distribution network. For a standard 7kW single-phase residential install, your licensed electrician manages compliance under their NSW electrical licence — no separate application to Endeavour Energy is required. For 22kW three-phase installs at a Norwest business premises or a residential property that does not currently have three-phase supply, a connection application to Endeavour Energy must be lodged and approved before the circuit can be energised. We hold Authorised Service Provider accreditation and prepare that application as part of the job — you do not need to coordinate with Endeavour Energy separately. Approval timelines are confirmed at the quote stage.

Detached double garages 15–25 metres from the meter box are the most common install condition in Castle Hill, not an exception. We survey the full cable path during the site visit — through the roof cavity, along the eaves, or in surface conduit where internal routing is not practical — and specify the correct conduit type and conductor gauge for the measured run length. Conductor sizing is increased where the run length would otherwise cause voltage drop beyond the allowable tolerance. Runs beyond 15 metres carry a transparent cabling surcharge confirmed in writing before any work starts. The fixed-price 7kW base rate covers up to 15 metres; everything beyond that is itemised and approved before we proceed.

Yes, and for most Castle Hill homeowners it is the best configuration available. Postcode 2154 has one of the highest residential solar penetration rates in Greater Sydney — over 5,259 systems with a combined 39,834 kW of installed capacity. A Zappi charger in eco mode monitors your solar export in real time and diverts surplus generation into the car rather than sending it back to the grid at the feed-in tariff rate. Evnex solar scheduling achieves the same result for compatible inverter brands. We assess your inverter make, generation profile, and any existing battery during the site visit and confirm the right charger and configuration for your setup before any work starts. If you mention solar when you enquire, we bring the right equipment for the site assessment.

The fixed-price 7kW install covers: site assessment, charger unit, RCD, weatherproof enclosure, up to 15 metres of cabling from your meter box to the installation point, commissioning, app pairing, and a certificate of electrical compliance. No travel fee within the Castle Hill area. For runs beyond 15 metres — standard on the large detached-garage blocks across 2154 — additional cabling is quoted separately before any work starts, based on the actual measured path. The cabling surcharge is itemised and confirmed in writing. Switchboard upgrades, if the site assessment finds one is required, are priced separately and approved before we proceed. We do not begin any scope that was not agreed at the quote stage.

For most Castle Hill houses on single-phase power, a 7kW Level 2 smart charger — Zappi, Evnex E2 Plus, or Tesla Wall Connector — is the right fit. The Zappi is particularly well suited to solar households given its native eco mode. These chargers accept a Type 2 connector, which covers the Tesla Model Y, Model 3, BYD Atto 3, Kia EV6, Polestar 2, and BMW iX — all common in the Hills District given the suburb’s buyer profile. A typical 60–80 kWh battery charges from near-empty overnight in 8–12 hours on 7kW single-phase, which suits most commuter households in the area. If your EV has a higher onboard charger rating and you want faster daytime top-ups, a 22kW three-phase install is available for compatible vehicles. We confirm the right charger for your car and property at the site assessment before any work starts.
