Why Powerwall 3
More power. Fewer parts. Zero compromises.
Powerwall 3 is Tesla's most capable home battery yet — engineered to handle your entire home during a Hawaii electric outage, not just a handful of circuits.
Whole-home backup
11.5 kW continuous and 185 A motor starting mean you can run AC, refrigerator, EV charger, and the rest of the house on battery — not just a few circuits.
Solar-to-home, direct
During an outage, your solar continues to charge Powerwall 3 and power the home directly — no daytime blackout, no waiting for the grid to return.
Expandable storage
Add up to three Powerwall 3 expansion units per system — scale from a single 13.5 kWh unit to 54+ kWh as your needs (or your EV) grow.
Built for the islands
IP67-rated for outdoor install, -4°F to 122°F operating range, and quiet operation — engineered to handle Hawaii sun, salt, and trade winds.
Smart charging capable
The weather alert function prioritizes charging your batteries in anticipation of inclement weather — so you head into a storm at full reserve, automatically.
Works with existing systems
Capable of integrating with some existing solar systems — we assess your current equipment and find the most cost-effective path to backup power. Ask about the latest battery incentive and rebate programs.
Tesla app control
Watch every watt in real time. Set backup reserves, storm-watch modes, and time-based control from your phone — anywhere in the world.
How it works
Sun by day. Stored by night. Backup on demand.
Daytime
Solar charges Powerwall
Your Qcells panels power the house first, then charge Powerwall 3 through its built-in inverter.
Nighttime
Battery powers the home
Instead of pulling expensive HECO power, your home runs off the sun you stored earlier that day.
Grid outage
Seamless backup power
Powerwall detects the blackout and keeps your home on — solar keeps charging so backup can last for days.
Prefer modular?
Enphase IQ Battery 10C.
Not every home needs a single big battery. The 4th-generation Enphase IQ Battery 10C stacks 10 kWh modules with PowerMatch microinverter technology — smaller footprint, fewer parts, and the same unmatched reliability. A great alternative to Powerwall 3 for smaller loads or phased build-outs.
Ask about EnphasePowerMatch
Auto-activates only the microinverters needed for real-time demand — higher efficiency, less waste.
Modular 10 kWh
Stack multiple units to match load and budget. Start smaller, expand later.
Fewer components
4th-gen redesign streamlines installs with smarter integration.
15-year warranty
Industry-leading warranty and remote monitoring via the Enphase app.
Keep your home on — no matter what the grid does.
We'll size a Powerwall 3 (or Enphase IQ) system to your loads, your solar, and your budget — and walk you through federal and Hawaii-specific incentives.
