Whole Home Backup or Critical Load Backup: Whole Home backup- Installed Tesla Backup Gateway (BMS) and CT's at the meter  location to intercept the main incoming supply so now the entire home is backed up. This home can now be self-powered under self-consumption mode with a chosen set % for emergency backup during power outages. Tesla Powerwall allows the system to sell the excess solar energy back to BCHydro via net-metering as well as allowing the property to remain self-powered, potentially Off-Grid indefinitely during a power outage. The system includes a real-time monitoring application so that the customer can manage/balance their electrical loads during grid failure.  

We were building a new home and wanted to go all solar. We contacted some other companies, but Tarum was the most professional in explaining our options and had competitive pricing. Tarum took care of all the ordering, permits and schedules, and worked with our builder for the installation.


He also contacted BC-Hydro to setup the net-metering account. It was a hassle-free and smooth process. As we were the first solar in our area, Tarum had to spend a day tutoring to the electrical inspectors how the solar system worked. We now have 44 solar panels installed on our roofs along with a battery backup system and it has been working great.
