Resilience guide
Keeping the lights on through a BC winter.
Atmospheric rivers and windstorms take out power across the North Shore, the Fraser Valley, and Sea‑to‑Sky every year. Here’s how a solar battery keeps your home running — and how it stacks up against a gas generator.

First, a surprise: solar alone won’t power your home in an outage
Grid‑tied solar is required to shut down during a grid outage — an anti‑islanding safety rule that protects line workers. So without storage, a blackout leaves even a solar home dark. The battery is what changes that: it isolates your home and keeps feeding it from stored energy.
How battery backup works
When the grid drops, a hybrid inverter disconnects your home and powers your chosen circuits from the battery — automatically, usually within a fraction of a second. Your solar keeps recharging the battery by day, so on a multi‑day outage you can ride through far longer than a single charge. You decide what’s protected: typically fridge/freezer, heat pump or furnace fan, internet, lights, and outlets for phones and medical devices.
Battery vs. generator
- Automatic — no going outside in a storm
- Silent, no fumes, indoor‑safe
- Recharges from your solar — no fuel
- Earns its keep daily (bill savings + Peak Saver)
- Up to $5,000 BC Hydro rebate (with Peak Saver)
- Runs indefinitely if you have fuel
- Lower up‑front cost for whole‑home
- Noise, fumes, refuelling, maintenance
- Does nothing on the other 360 days a year
- No rebate; fuel logistics during storms
For most Metro Vancouver homes, a battery wins on convenience and daily value; a generator can still make sense for very long rural outages or whole‑home heavy loads. The two aren’t exclusive — we can design a battery as primary backup with a generator as a deep‑backup layer.
