WHY BATTERIES
Why Canadian Homeowners Choose Battery Storage
Ice storms in Ontario. Chinooks in Alberta. Winter storms across BC. Canadian homeowners face power outages sometimes for days.
A whole home battery backup system keeps your critical loads running when neighbors go dark. No fuel storage & manual startup.
REGIONAL ADVANTAGES
Battery Storage Benefits by Province
Alberta
Alberta's deregulated electricity market means prices fluctuate throughout the day. Battery storage lets you buy low and use high.
With increasing extreme weather events and grid strain, backup power provides essential protection for Calgary, Edmonton, and rural Alberta homes.
LITHIUM-ION TECHNOLOGY
How Home Battery Storage Works
Modern residential energy storage systems use lithium-ion technology, the same proven chemistry powering electric vehicles, scaled for home energy needs.

Solar panels or grid power charges your battery during optimal periods
Energy stored in lithium-ion cells at 90-97% round-trip efficiency
System automatically discharges when you need power or rates are high
During outages, battery disconnects from grid and powers your home
The entire system operates automatically. Modern home battery systems produce reliable backup power for 15+ years with proper installation.

SYSTEM SIZING
Battery System Design Considerations
Critical Load Identification
What absolutely must stay powered during outages? We prioritize circuits based on your specific needs and lifestyle.
Capacity Sizing
Most residential systems range from 10-20 kWh. We calculate your specific requirements based on actual usage data—not guesswork.
Electrical Integration
Proper disconnects, protection devices, and code compliance ensure safe, reliable operation for years to come.
BUSINESS SOLUTIONS
Commercial Battery Storage
Business owners face unique energy challenges. Commercial battery storage addresses peak demand charges, provides operational resilience, and can generate revenue through utility programs.
Batteries offset demand charges which often represent 30-50% of commercial electricity costs.
