Lithium-ion and emerging battery engineering, from residential to utility-scale. Sizing, integration, safety, and interconnection under CSA, UL, and NFPA standards.

How big of a battery do I need for whole-home backup?

A typical 3-bedroom home in Ontario needs 10–15 kWh for essential loads (lights, fridge, furnace fan) for 8–12 hours. Full home backup including AC and EV charger may require 20–30 kWh. We model your specific loads to right-size the system.

Key Deliverables

• Battery sizing calculation (kWh capacity, kW power rating)
• Integration single-line diagram, P.Eng stamped
• Protection coordination study for BESS
• Thermal management specification
• Fire safety compliance review (NFPA 855)

What is the difference between AC-coupled and DC-coupled?

AC-coupled systems connect the battery inverter to your AC panel, which is simpler for retrofits. DC-coupled systems share the solar inverter and are more efficient for new solar+storage installations. We recommend based on your existing equipment and goals.
