Residential batteries are revolutionizing the way we consume electricity. They store energy when it is abundant (daytime with sun, or low night rates) to deliver it when you need it.

Paired with solar panels, they allow you to use your own green energy in the evening and at night. Without solar, they provide reliable protection against power outages, ensuring your essential equipment stays powered.

At Arsenal Électrique, we install state-of-the-art lithium-ion battery systems with integrated inverter and automatic transfer system. Control your consumption via mobile app and optimize your energy savings.

Autonomy duration depends on battery capacity and your consumption. A standard 13.5 kWh battery can power essential equipment (refrigerator, lighting, basic heating) for 8 to 12 hours. For complete home autonomy, multiple batteries can be installed in parallel. We size the system according to your specific needs.
Yes, batteries can be charged from the Hydro-Québec electrical grid. This configuration provides backup power during outages without investing in solar panels. However, pairing with solar maximizes savings and autonomy.
Lithium-ion batteries (like Powerwall, LG Chem) offer superior energy density, longer lifespan (10-15 years), faster charge/discharge, and require no maintenance. Lead-acid batteries are cheaper initially but have a shorter lifespan (3-5 years), require regular maintenance, and have lower efficiency. We recommend lithium-ion for residential installations.
Yes, that is precisely their main function. As soon as an outage is detected, the battery system automatically switches to power your home within milliseconds. You won't even notice the interruption. When the grid returns, the battery recharges automatically.
Cost varies depending on capacity and brand. Expect between $12,000 and $18,000 for a quality lithium-ion battery (13-15 kWh) with complete installation and automatic transfer system. Savings on electricity bills (with solar) and peace of mind during outages justify the investment. Subsidies may be available.
Yes, modern batteries incorporate multiple safety systems: protection against overcharging, overheating, short circuits, and active thermal management. They are certified to strict UL 9540 and UL 1973 standards. Installation by a certified electrician ensures safe integration with your electrical system.
