tesla home charger installation edmonton


A recent client was expecting his new Tesla Model Y to arrive later in the month. As the arrival date approached, he began to start looking at options for installing an EV charger in his home.

The Problem:

After looking around at different contractors and getting some quotes, he was told that he would not be able to install more than 16 Amp of power for his new charger, resulting in 17 km of range per hour. All other contractors were worried that his 100 Amp main service would not be able to handle the addition of the new EV charger.

Upgrading his electrical service to 200 Amp would require excavation on his and the city property. Since his service is fed underground from the street, the cost to upgrade the underground wires and service equipment was more than $10,000 of EPCOR fees alone.  Without the upgraded service his new ludicrously fast Tesla would be insanely slow to charge.  That’s when he reached out to BLDG through our website for another solution.

The Solution:

We performed a load calculation on the house. This determined that there was a maximum of 28 Amp available space on his service, as per the Canadian Electrical Code.

Upon investigation of his electrical service and panel, the team at BLDG came up with a game plan to install a 40 Amp EV Energy Management System and his new Tesla Gen 3 Wall Connector.

The EV Energy Management System takes amperage readings of his main service and will shut down the EV charger if his service reaches 80% capacity.  If the service drops below 80% usage for more than 15 minutes it will re-enable the charger. 

Because of this solution, his Tesla EV charger will be running at max capacity for a 100 Amp service - charging at 32 Amp continuously, allowing him to get approximately 48 km of range per hour!

We then ran the 40 Amp service out to his attached garage to connect the Tesla Gen 3 Wall Connector.

This was a fantastic solution for the client, as the DCC-10 Load manager is a much more cost-effective solution than upgrading his main service, and it still leaves the homeowner space on their service for future renovations or upgrades.

The entire install was performed during the morning, inspected and energized all in the same day!

All the leg work and coordination that was put in beforehand meant this project was seamless from start to finish.
