TECHNOLOGY — TESLA POWERWALL

Built for the Long Outage

Powerwall 3 pairs a whole-home battery with a built-in solar inverter, so backup power isn’t bolted onto your system as an afterthought — it’s engineered in from the start.

The Battery That Also Runs Your Solar

Most home batteries need a separate inverter box bolted alongside them — one more enclosure on the wall, one more point of failure, one more thing to service down the road. Powerwall 3 folds an 11.5 kW solar inverter directly into the unit itself. Fewer components, cleaner wiring, and an installation that reads as one deliberate instrument rather than a collection of parts wired together after the fact.

One Box. Four Jobs.

  • Built-in solar inverter — up to 20 kW of solar input, integrated directly into the unit rather than a separate box on the wall
  • 13.5 kWh of storage — expandable with additional Powerwall or Expansion units as your household’s needs grow
  • 11.5 kW continuous power — enough to run essentially any household load, from central air to a well pump
  • Tesla app control — real-time monitoring, storm watch, and remote diagnostics from anywhere

What This Buys You

Reliability

Whole-home backup that engages automatically the instant the grid drops — no generator, no fuel, no noise, no waiting.

Simplicity

One integrated unit means fewer components mounted to your wall, fewer points of failure, and a cleaner, quieter installation from day one.

Scalability

Add capacity as your needs grow — additional Powerwall or Expansion units scale the system without re-engineering what’s already installed.

One Partner, Every Watt

Solar, storage, EV charging, and electrification services are rarely sold as one relationship — they’re usually stitched together from separate vendors, separate warranties, separate service calls. We install and service all of it, so the charger in your driveway and the battery on your wall are designed to work as a single system, not a collection of coincidences.
