Commercial EV Chargers

The number of chargers depends on:

• staff EV numbers

• expected customer or visitor usage

• fleet size

• electrical capacity

• dwell time (how long vehicles stay parked)

• future EV adoption plans

We assess all of this to design an EV charging plan that avoids bottlenecks and keeps costs efficient.

Yes. Smart chargers allow you to:

• set pricing

• restrict usage to staff only

• offer discounted rates

• create revenue streams

• integrate payment systems

Many businesses offset their installation cost through EV charging revenue.

Most AC chargers are installed in 1–3 days.
Larger projects with civil works or multiple DC chargers can take 1–3 weeks.

We manage end-to-end approvals, installation, commissioning, and training.

Commercial EV charger installations typically range from:

• $3,000–$8,000 per AC charger (installed)

• $40,000+ for DC fast charging (installed)

Costs depend on cable runs, civil works, switchboard upgrades, trenching, and charger type. Sharp EIT provides fixed-price proposals after a site assessment.

Yes. EV chargers can:

• draw directly from your solar system

• prioritise solar energy before grid power

• reduce daytime charging costs

• improve your sustainability reporting

This is ideal for workplaces with daytime charging needs.

Absolutely. EV chargers can run entirely from the grid. You can add solar later to reduce electricity costs and improve sustainability performance.

AC chargers (Level 2)

• Best for workplaces, fleets, and longer parking times

• Lower installation costs

• Slower charging (6–11kW)

DC chargers (fast charging)

• Best for high turnover, fleets, logistics and public use

• Higher installation + electrical requirements

• Much faster charging (25kW–150kW+)

Charging times depend on:

• AC vs DC

• charger speed (kW)

• car battery size

• starting battery level

• load management settings

AC charging can take 1–6 hours, while DC fast chargers can top up a vehicle in 15–45 minutes.

Not always, but it helps.

• Single-phase supports basic AC charging (up to 7kW).

• Three-phase supports faster AC charging (11–22kW) and is usually required for DC charging.

We assess your electrical supply before installation.

No — with dynamic load management, Sharp EIT ensures your chargers never exceed your electrical capacity.

Charging automatically scales up or down based on building load.

Yes. We install EV chargers in:

• underground car parks

• multi-level car parks

• retail centres

• apartment buildings

• office basements

Ventilation, cable pathways and switchboard access are assessed first.

Yes — commercial systems benefit from:

• firmware updates

• monitoring

• preventative maintenance

• safety checks

• occasional hardware servicing

Sharp EIT offers service packages to maximise uptime and reliability.

Most standard installations do not require council approval.

You may need approvals if:

• trenching crosses public land

• external signage is required

• large-scale DC chargers are being installed

• major switchboard upgrades are needed

We handle all required permissions.

Yes. Smart EV chargers can integrate with:

• fleet management platforms

• building access cards (RFID)

• billing systems

• energy management systems

• load control systems

This is ideal for multi-site or enterprise environments.

It depends on your operation:

• Workplaces: AC wall or pedestal chargers (slower but cost-effective)

• Customer parking: Mix of AC + some DC

• Logistics & fleets: Faster AC or DC chargers

• Multi-site enterprises: Centralised management + smart load balancing

• Retail or high traffic: DC fast charging

We match the right technology to your usage and budget.
