Collection: Home Battery Backup Systems

A home battery backup system keeps your fridge, furnace fan, lights, well pump and internet running when the grid goes down, then stores solar power to cut your bills the rest of the time. Each system here pairs a hybrid or storage inverter with LiFePO4 batteries and connects to your home's electrical panel. Systems ship from our Waterloo, Ontario warehouse.

Which backup system fits your home?

System Best for
Growatt SPH 10000 + GSL 14.34–28.68 kWh Essential circuits or a load-managed whole home, 120/240V, with room for up to 15 kW of solar
Growatt 3.8–6 kW partial home backup Smaller homes that want the essentials covered: fridge, furnace fan, lights, internet
Growatt 11.4 kW whole home backup Larger homes that want more circuits backed up
Canadian Solar EP Cube 2.0 An all-in-one battery and inverter system for homes with or without solar
GSL 14.34 kWh battery on its own Adding storage to a 48V hybrid or off-grid inverter you already have

How much battery do you need?

  • Essentials overnight (fridge, furnace fan, lights, internet): about 10–15 kWh.
  • Essentials plus a well or sump pump: about 15–30 kWh.
  • Most of the home through long outages: 30 kWh and up, with solar to recharge.

Electric baseboards, electric furnaces and EV chargers draw more power than most backup systems can supply for long, so they usually stay off the backup panel. Call us with your list of loads and we'll size a system for you.

Batteries in a Canadian winter

Most LiFePO4 batteries can't be charged below 0°C. Install them in a basement, utility room or heated garage, or choose the self-heating GSL battery for unheated spaces.

Installation

A backup system connects to your electrical panel, so a licensed electrician must install it, with a permit and inspection where required. Rebate programs such as BC Hydro's set their own product and installer rules; check them before you buy.
