4. Improved Control with Advanced Circuit Protection
You gain significant control benefits with a modern switchboard designed for solar. Advanced circuit protection ensures your solar equipment operates safely and efficiently. The ability to isolate solar circuits independently means maintenance becomes simpler and safer. You can also optimize your energy consumption by understanding which appliances draw power when your panels are producing at peak capacity.
Why Upgrading Your Switchboard is Essential for EV Charging
Installing an EV charger requires more from your electrical system than most household appliances. A typical Level 2 home EV charger uses between 7.2 to 19.2 kilowatts—similar to running several air conditioners at once. To avoid overheating and potential fire hazards, such as those caused by frequent circuit breaker tripping, your switchboard needs a dedicated circuit breaker specifically rated for this continuous high-power usage.
Challenges Older Electrical Systems Face with EV Charging
Older electrical systems have a hard time supporting the power needed for EV charging. Homes built before the 1990s usually have switchboards made for maximum loads of 60-80 amps, while modern EV charging can need 40-50 amps on its own circuit. When you consider your regular household energy use, you’ll quickly go over your system’s capacity.
Common Issues with Aging Electrical Infrastructure
The increased power requirements often expose hidden problems in older electrical systems:
Rewiring becomes necessary when your existing cables can’t handle the amperage. Many homeowners discover they need to upgrade to a three-phase power supply for faster charging capabilities. Three-phase power delivers electricity more efficiently, reducing charging times from 8-10 hours to 3-4 hours for a full battery. This upgrade requires comprehensive switchboard modifications to accommodate the additional phases and proper load distribution across your electrical system.
