Home Batteries & Energy Storage
Home battery systems store energy from solar panels or the grid, giving you backup power during outages and the ability to use cheap off-peak electricity during peak hours. New technologies like molten salt batteries promise even longer-lasting, safer storage.
Types of Home Batteries
- Lithium-ion — most common (Tesla Powerwall, Enphase). Compact, efficient, 10-15 year lifespan
- Lithium iron phosphate (LFP) — safer chemistry, longer cycle life, increasingly affordable
- Molten salt batteries — emerging technology using abundant materials. Extremely long lifespan, no fire risk, works in extreme temperatures. Ideal for whole-home storage
- Flow batteries — scalable, very long lifespan, best for large installations
What Batteries Do for You
- Backup power — keep your lights, fridge, and essentials running during outages
- Peak shaving — store cheap off-peak power, use it during expensive peak hours
- Solar optimization — use your solar energy at night instead of selling it cheap
- Grid independence — reduce reliance on the utility company
- Future-proof — as electricity prices rise, stored energy becomes more valuable
Molten Salt: The Next Generation
Molten salt batteries use sodium and other abundant materials instead of lithium. They cannot catch fire, operate safely from -40C to +60C, and can last 20+ years with minimal degradation. Several companies are now bringing residential molten salt systems to market, making them a compelling choice for Canadian homeowners.
