Tesla Certified Installer for Powerwall 3 systems across Greater Cincinnati and Northern Kentucky. Custom-designed whole-home battery backup, multi-unit configurations for larger homes, and integration with Tesla EV chargers and solar.
The Powerwall 3 is Tesla's current generation home battery, released in 2024 to replace the Powerwall 2. It's a fundamentally redesigned product with several key advantages over the previous generation.
Integrated inverter. The Powerwall 2 required a separate inverter for solar integration. The Powerwall 3 has the inverter built in, simplifying installation and reducing equipment cost. For homes that don't have solar but want battery backup, the Powerwall 3 provides AC output directly without additional inverter hardware.
Higher continuous power output. The Powerwall 3 delivers 11.5 kW of continuous power, up from 5 kW on the Powerwall 2. That's enough to handle high-draw loads (HVAC startup surges, well pumps, multiple appliances) that would have tripped the Powerwall 2.
Solar input direct to the unit. The Powerwall 3 accepts up to 20 kW of solar input directly, eliminating string inverters in many configurations.
Modular expansion. Each Powerwall 3 supports up to 3 expansion packs (Tesla's "Powerwall 3 Expansion Pack"), which add storage capacity without requiring additional primary units. Scaling capacity is more affordable than buying additional primary units.
System-level scaling. Up to 4 primary Powerwall 3 units can be paralleled, with each supporting up to 3 expansion packs, for a maximum system capacity of approximately 94 kWh and 46 kW of continuous power.
The right number of Powerwall 3 units and expansion packs depends on what you want to back up, how long you want to run on battery, and whether you have or plan to add solar.
Appropriate for critical loads backup in smaller homes, typical 1-3 day Cincinnati outages, homeowners who want battery backup without solar and don't need extended runtime, or budget-conscious entry into battery storage.
Adding 1-3 expansion packs to a single primary unit gives you additional storage without doubling installation cost. Good for extended runtime on critical loads, buffer capacity for homeowners who plan to add solar later, or mid-size homes with moderate-to-high critical loads.
Larger homes or higher backup goals call for multiple primary units. Whole-home backup capability (running everything in the house, not just critical circuits), estate-sized homes with high baseline electrical demand, homes with multiple high-draw items (multiple AC units, electric ranges, EV chargers, hot tubs), or maximum continuous power output for complex loads.
The full Powerwall 3 system maximum is designed for very large estate properties, homes with extended outage protection requirements, solar-paired systems where battery cycles daily and storage capacity drives autonomy, or homes with critical medical or business operations that require uninterrupted power.
Standard installation scope includes:
For households with one or more Tesla vehicles, Powerwall 3 integrates directly with the Tesla ecosystem.
Charge from Powerwall during outages. When the grid is down, your Tesla can continue charging from the Powerwall 3, allowing you to maintain mobility during extended outages. The system automatically manages charging rates to preserve battery capacity for home use.
Single app for everything. The Tesla app shows Powerwall status, energy flow, vehicle charge state, and (if applicable) solar production in one interface.
Storm Watch. Tesla's Storm Watch feature uses National Weather Service alerts to automatically charge the Powerwall to full capacity ahead of forecast severe weather.
Time-based control. Configure when the Powerwall charges from grid versus discharges, optimizing for your specific utility rate structure or backup priorities.
Powerwall 3 is solar-ready out of the box. The integrated inverter accepts up to 20 kW of DC solar input directly, eliminating the need for a separate string inverter in many configurations.
For Cincinnati homeowners considering solar plus storage as a combined investment, the Powerwall 3's solar capabilities can simplify the system design and reduce overall equipment cost. We work with regional solar partners on combined installations and can quote the battery scope independently for homeowners working with their own solar contractor.
Tesla's Certified Installer program is selective. Certified installers must complete Tesla's training program, maintain documented technical capability, carry appropriate insurance and licensing, pass periodic compliance reviews, and use Tesla's design tools and approved installation methods.
Working with a non-certified installer creates risk: Tesla's hardware warranty may not apply, manufacturer support is limited, improper installation can damage the Powerwall and void warranty coverage, and future service depends on certified installer access.
You can verify any installer's certification status on Tesla's installer locator at tesla.com.
Tesla Powerwall installations available throughout Greater Cincinnati and Northern Kentucky, including Indian Hill, Hyde Park, Mason, Blue Ash, and Northern Kentucky. View all service areas →
Typical single-unit installations are completed in 2 to 3 days of on-site work, plus permitting time. Multi-unit installations or installations requiring service upgrades take longer.
No. The Powerwall 3 works as a standalone battery backup system without solar. Many Cincinnati installations are battery-only configurations charged from the grid.
Yes. The Powerwall 3 is designed to accept solar input. Adding solar in the future is straightforward.
Tesla has phased out the Powerwall 2 in favor of the Powerwall 3. New installations use the Powerwall 3.
Every installation is custom-quoted after an on-site assessment. Pricing depends on the number of units, existing panel configuration, backup load requirements, service capacity, and installation complexity. Financing available through Wisetack for qualifying installations.
Depends on system size and home load. A single Powerwall 3 (11.5 kW continuous) can run most appliances simultaneously but may struggle with very high baseline loads (multiple AC units, electric range, dryer all running at once). Multi-unit systems can run whole-home loads in most homes.
Tesla provides a 10-year manufacturer warranty on the Powerwall 3 hardware, with specific terms covering capacity retention. Our installation work is covered separately by our workmanship warranty.
With proper Duke Energy interconnection agreement, yes. Most homeowners use the Powerwall 3 primarily for backup rather than grid export, but the option is available.
Powerwall 3 installations are typically scheduled 4 to 8 weeks out depending on equipment availability, permit timelines, and Duke Energy coordination. We provide specific timing during the estimate.
