Battery Backup & Home Energy Storage

Keep your home powered when the grid goes down. Ground Zero Electric installs battery backup systems that store energy from the grid or solar - giving you seamless, automatic backup power during outages and the ability to reduce your electricity costs year-round.

We're certified to install the industry's leading residential battery systems and handle everything from site assessment to permitting and final commissioning.

Why Battery Backup?

Greater Cincinnati averages multiple power outages per year from storms, grid strain, and aging infrastructure. A battery backup system eliminates the inconvenience and risk - no generator fuel, no extension cords, no noise. Your power stays on automatically.

  • Instant automatic switchover during outages - no interruption to your home
  • Works with or without solar panels - charges from the grid when solar isn't installed
  • Protects sensitive electronics, medical equipment, sump pumps, and refrigeration
  • Reduces electricity costs with time-of-use optimization
  • Silent operation - no generator noise, no exhaust, no fuel storage
  • Scalable - add battery capacity as your needs grow

Systems We Install

Who Should Consider Battery Backup?

  • Homeowners in areas with frequent outages or aging utility infrastructure

Battery Backup vs. Generator

Generators have been the default backup power solution for decades, but battery systems have changed the equation. Here's how they compare.

Transfer TimeBattery: under 20 milliseconds (instant). Generator: 10-30 seconds (electronics may reset).
NoiseBattery: silent. Generator: 60-90 dB (lawnmower-level noise).
FuelBattery: none (charges from grid or solar). Generator: gasoline, propane, or natural gas (ongoing cost).
MaintenanceBattery: virtually none. Generator: $200-600/year (oil, filters, spark plugs, test runs).
LifespanBattery: 10-15 years, LFP chemistry can reach 15-20 years. Generator: 20-30 years with proper maintenance.
Daily ValueBattery: saves money year-round through peak shaving and time-of-use optimization. Generator: only provides value during outages.
EmissionsBattery: zero. Generator: carbon monoxide, exhaust (cannot run indoors or enclosed spaces).
Storm ReadinessBattery: auto-charges to 100% when storms are forecast. Generator: depends on fuel level and mechanical readiness.

Generators still make sense for extended multi-day outages in rural areas where fuel is accessible. But for most Cincinnati homeowners, a battery system offers better day-to-day value, faster response, and less hassle. The Anker SOLIX E10 even offers a hybrid option: battery backup with an integrated tri-fuel smart generator for the best of both worlds.

Common Questions

No. Battery systems can charge from the grid alone. You'll still get backup power during outages and can save money with time-of-use rate optimization. Solar can always be added later.

It depends on the system size and what you're running. A single 13.5 kWh battery can power essential loads (refrigerator, lights, Wi-Fi, sump pump) for 10-12+ hours. Multiple batteries or larger systems extend that significantly.

Yes, depending on the system. Both Tesla Powerwall 3 and Anker SOLIX E10 are designed to handle high-draw loads including central AC. System sizing matters - we'll assess your AC unit during the site visit.

Systems range significantly based on capacity and configuration. Contact us for a site assessment and detailed estimate specific to your home and energy needs.

Not always. We assess your existing panel capacity during the site visit. Some installations integrate cleanly with your current panel; others may need an upgrade or subpanel. We handle all of it.

Batteries switch on instantly (under 20 milliseconds), run silently, require no fuel, and need virtually no maintenance. Generators require fuel storage, regular maintenance, produce noise and exhaust, and take seconds to start - which can disrupt sensitive electronics.

Yes. Both Tesla Powerwall and Anker SOLIX systems are designed for modular expansion. We plan the initial installation with future growth in mind.
