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.

Our Process

  • Outage and load evaluation
  • System design and equipment selection
  • Permits and BC Hydro coordination
  • Professional installation and commissioning
  • Monitoring setup and client handover
