Home EV Charging in WA: Everything You Need to Know

EV sales in WA are climbing fast. If you've bought one (or you're about to), a home charger pays for itself quickly -- no more public charger queues, and your running costs drop to a fraction of what you'd pay at a public station.

Why Charge at Home?

Home charging beats public charging on every metric:

• Convenience: Wake up to a full battery every morning
• Cost: Home electricity is cheaper than public chargers
• Time: Charge overnight while you sleep
• Solar integration: Use your own solar power for essentially free fuel

The Cost Comparison

| Charging Location | Cost per kWh | Cost per 100km | |-------------------|--------------|----------------| | Home (standard rate) | $0.32 | $5.76 | | Home (EV tariff) | $0.15 | $2.70 | | Home (solar) | $0.00 | $0.00 | | Public AC charger | $0.45 | $8.10 | | Public DC fast charger | $0.60+ | $10.80+ |

Based on average EV consumption of 18 kWh per 100km

Synergy's Electric Vehicle Tariff Explained

Synergy offers an EV Add-On plan with cheap overnight rates that cut your charging costs roughly in half.

How It Works

• Time-of-use pricing with cheap overnight rates
• Super off-peak: 9pm - 7am at around $0.15/kWh
• Peak: 3pm - 9pm at higher rates
• Standard: All other times at normal rates

Who Should Use It?

The EV tariff is beneficial if:

• You can charge overnight (most EV owners)
• You have a smart charger with scheduling
• Your general usage doesn't increase during peak times

Requirements

• Smart meter installation (free from Synergy)
• Compatible EV charger with scheduling
• At least one registered electric vehicle

Solar + EV Charging

Solar and EV charging together is where the real savings stack up:

The Numbers

• Average EV annual distance: 15,000km
• Energy required: 2,700 kWh
• Cost on standard tariff: $864/year
• Cost on EV tariff: $405/year
• Cost with solar: $0-100/year

Smart Solar Charging

Modern EV chargers like Zappi can automatically:

• Detect surplus solar generation
• Adjust charging speed to match available solar
• Switch to grid power when clouds pass
• Resume solar charging when sun returns

This means your EV essentially runs on free fuel from your roof.

Installation Requirements

Electrical Considerations

Before installing a home charger, consider:

Single-Phase vs Three-Phase

| Connection | Max Charger Speed | Notes | |------------|-------------------|-------| | Single-phase | 7.4kW | Most WA homes | | Three-phase | 22kW | Faster charging, requires upgrade |

Most WA homes have single-phase power, which supports chargers up to 7.4kW—enough to fully charge most EVs overnight.

Switchboard Capacity

Your electrician will assess:

• Available capacity on your switchboard
• Need for any upgrades
• Circuit breaker requirements
• Cable runs to the charging location

Ideal Charger Placement

Consider these factors:

• Proximity to switchboard: Shorter cable runs = lower cost
• Vehicle parking position: Easy access to charge port
• Weather protection: Undercover locations preferred
• Future needs: Will you have a second EV?

Installation Process

Timeline

1. Site assessment (1-2 days): Electrician visits, provides quote
2. Order and permit (1-2 weeks): Charger ordered, permit if required
3. Installation (half day): Charger mounted and wired
4. Testing and handover (1 hour): System checked, app setup

Typical Costs

| Component | Cost Range | |-----------|------------| | EV charger unit | $1,100 - $2,500 | | Installation (standard) | $500 - $1,000 | | Installation (complex) | $1,000 - $2,000 | | Switchboard upgrade (if needed) | $500 - $2,000 | | Total typical | $2,000 - $4,500 |

Common Questions

Can I use a regular power point?

Yes, but it's not ideal for daily use:

• Very slow (10-15km range per hour)
• May overload older circuits
• Not designed for sustained high loads
• No smart features or scheduling

Do I need a permit?

In most WA cases, no permit is required for:

• Chargers up to 32A on existing circuits
• Standard residential installations

Your electrician will advise if permits are needed.

Will it increase my electricity bill?

Your bill will increase, but you'll save money overall:

• EV charging replaces petrol costs
• Average EV costs $800-1,200/year to charge
• Average petrol car costs $2,500-4,000/year
• Net savings: $1,500-3,000 per year

Can I charge in the rain?

Yes! All certified EV chargers are:

• Rated for outdoor use (IP65 or better)
• Designed with weather sealing
• Safe in all Australian conditions
