Keep The Lights On When The Grid Goes Out

Storms, wind events, and winter outages are part of life on Vancouver Island. Battery energy storage lets your home or business stay powered when the grid goes dark — without the noise, fuel, or maintenance of a generator.

Netzero Solar designs and installs grid-tied battery backup systems, using proven brands such as Enphase Energy, EG4 Electronics, and LuxpowerTek, to keep your essential loads running when you need them most.

Why Add Battery Storage?

Reliable Backup During Outages

Battery storage keeps critical loads powered, such as:

Refrigerators and freezers
Internet and work-from-home equipment
Key lighting circuits
Furnace or boiler controls
Garage doors and security systems

Unlike generators, batteries are silent, automatic, and require no fuel or ongoing maintenance. When paired with a PV solar System, batteries store excess daytime production so you can use it in the evening or during outages. This increases self-consumption and reduces dependence on the grid.

Essential Backup (Our Standard Design)

Most systems are built around a critical loads electrical panel, which powers only your most important circuits during an outage. This approach:

Keeps costs reasonable
Protects battery health
Prioritizes what actually matters
Avoids overload conditions

When total home backup independence is required from the grid, larger energy storage systems can support expanded or whole-home backup when appropriate.

Typical Battery System Sizes

Small Backup (5–10 kWh)

Short outages
Internet, lighting, fridge, essential plugs

Medium Backup (10–20 kWh)

Multi-hour to overnight outages
Kitchen circuits, home office, gas furnace controls

Larger Backup (20+ kWh)

Large homes or rural properties
Multiple fridges, pumps
Longer outage coverage with load management

System size is always matched to your real-world usage.

How It Works With The Grid

All systems installed by Netzero Solar remain fully grid-tied.

Solar powers your home first
Excess solar energy can charge batteries
During outages, the system isolates and powers only backed-up circuits
When the grid returns, everything reconnects automatically

No off-grid configurations. No unsafe workarounds.
