When the power goes out in the middle of dinner, most solar systems shut down. That’s because grid-tied solar in Canada must follow strict safety rules, known as anti-islanding, which prevent electricity from flowing back into the grid while utility workers are repairing lines. The result? Even if the sun is shining, your solar panels don’t power your home during an outage.

That’s where home battery backup systems come in.

SolarEdge home battery backup systems stores solar energy for later use and keep your home running when the grid goes down. SolarEdge home battery backup system offers peace of mind in the face of outages, rising utility rates, and the need for energy independence.

Based in Vernon, Roost Solar installs SolarEdge home battery backup systems across the Thompson-Okanagan — from Salmon Arm to Kamloops and Kelowna and beyond

What Is Solar Edge Home Battery Backup

SolarEdge offers lithium-ion home batteries that work with y our solar PV system to provide reliable backup power. It stores excess solar energy generated during the day, so you can use it at night or during outages.

In B.C., where Fortis and BC Hydro already provide net metering, the main benefit of home batteries isn’t saving daytime solar for nighttime use — it’s the ability to keep your solar array producing power even if the grid is down.

For rural homeowners or those with critical loads (like medical equipment, refrigeration, or well pumps), that’s a game changer.

Learn more about our home storage solutions to see if SolarEdge home battery backup is right for your home.

For most B.C. households, one SolarEdge battery is enough to cover a few critical loads like lights, outlets, and a fridge. Larger homes, or those wanting whole-home backup, may require three or more batteries.

How Much Does SolarEdge Home Backup Cost?

The cost of battery backup depends on your location, electrical setup, and whether you’re pairing it with a new solar installation. On average, homeowners can expect:

  • Backing up Critical loads $25,000 – 50,000 CAD (installed)
  • Whole home backup: $65,000 CAD (installed)

While it’s a significant investment, many families see it as a form of insurance against outages and a way to protect critical appliances. Plus, pairing battery backup with solar gives you greater independence from rising electricity costs.

Benefits of Home Battery Backup in B.C.

Even though Fortis and BC Hydro already act like a “free battery” with net metering, SolarEdge home battery backup systems still offers important benefits:

  • Backup power during outages
  • Critical load protection (fridge, freezer, medical equipment, lights)
  • Peace of mind in rural areas with frequent grid interruptions
  • Energy independence and future readiness

And thanks to its sleek design and SolarEdge’s intuitive app, you can monitor your energy use in real time — tracking how much power comes from your solar system, the grid, or the battery itself.

  • Experience frequent outages,
  • Rely on critical electrical loads, or
  • Want greater energy independence…

…then pairing a solar PV system with home battery backup may be the right move.
