What charger power should I choose?
Do not choose from the vehicle alone. Review the car’s charging capability, building electrical supply, main breaker, existing loads and the available charging time.
EV CHARGING
EV Charger Installation
EV charging designed around existing electrical capacity, cable distance, usage pattern and solar integration for homes, hotels, buildings and factories.
CHALLENGE
Start from the problem that actually needs solving
A wallbox is not selected from the car model alone. Building capacity, main breaker, cable distance and simultaneous loads affect safety and charging performance.
Best suited to: Homes, hotels, offices, retail, factories and parking facilities
ENGINEERING APPROACH
Collect the right data before selecting equipment
- Review vehicle and target charger power
- Check single/three-phase supply, distribution board and available capacity
- Plan cable route, protection and charger location
- Consider load management or solar integration where appropriate
SCOPE
A practical scope for the first site discussion
- Electrical survey
- Circuit and protection design
- Charger and cabling installation
- Charging test and handover
OUTCOME
What should become clearer after the site survey
- Know what charger level the existing electrical system can support
- See any upgrades required before installation
- Have a path for future solar or additional chargers
Equipment, warranty, timeline and pricing are confirmed from verified site information and the final project quotation.
Frequently asked questions
Questions before a EV Charging site survey
Can a single-phase home install an EV charger?
It may be possible at an appropriate power level, but the electrical capacity and existing loads should be checked first.
Can solar help charge the EV?
Charging can be planned around solar production, but it depends on when the vehicle is present, other site loads and the solar system size.
Do I need three-phase power before installing an EV charger?
Not in every case. The charger requirement, existing supply, main breaker, other building loads and available charging time should be reviewed before deciding whether an electrical upgrade is needed.
Can an EV charger be installed outdoors?
It can be, provided the equipment and location suit the environment. Weather exposure, cable routing, protection devices and the actual parking arrangement should all be considered.
