A Citadel system, built around your house
Why consider Tesla Powerwall 3?
Powerwall 3 combines battery storage and power conversion in an integrated platform. Citadel starts with what your house asks of it: the circuits you want supported, equipment starting demands and how much energy you use during an outage. That is the foundation for selecting the number of Powerwall 3 units, not a blanket whole-home promise.
A clear capacity baseline
Each Powerwall 3 provides 13.5 kWh of nominal battery energy. Additional units increase stored energy, while the complete system configuration determines usable output.
Plan around demanding loads
Up to 11.5 kW continuous AC output per unit is configuration-dependent. Air-conditioning startup, simultaneous loads and grid requirements still need individual review.
Citadel reviews backup controls, circuit selection, electrical service, placement and any existing solar integration. This offering lists complete Powerwall 3 units only. Solar installation is not part of this battery offer.
Standard totals by battery count
13.5 kWh nominal energy per battery. Power output requires separate configuration review.
| Count | Energy (kWh) | System total |
|---|---|---|
| 1 | 13.5 | $21,500 |
| 2 | 27 | $41,000 |
| 3 | 40.5 | $60,000 |
| 4 | 54 | $79,000 |
| 5 | 67.5 | $98,000 |
| 6 | 81 | $117,000 |
Up to 11.5 kW continuous per Powerwall 3, subject to configuration. Assessment confirms scope; listed totals do not specify permit or electrical-upgrade inclusions.

Your assessment reviews priority loads, runtime expectations and installation scope.
Holiday battery offers apply separately to battery systems and do not stack with other promotions. Your assessment confirms installation scope, permit requirements and any electrical or site-specific work before an agreement. Listed totals do not specify those inclusions.
View the dedicated holiday battery offerEnergy is not power
kWh stores energy. kW delivers power.
A 15 kWh battery does not automatically provide 15 kW of output. Energy capacity describes how much is stored; output describes the power available at a moment in time.
Runtime depends on your selected loads, energy use, starting charge and the system’s usable reserve. We plan capacity around those priorities.
Air conditioning needs particular attention: starting current, continuous draw and simultaneous loads must fit the configuration. Your assessment confirms whether requested A/C loads can be supported.
Citadel reviews your North Texas home before recommending a system. Existing solar compatibility can be assessed separately; new solar installation is outside this offer. Manufacturer information provides product-specific warranty details.
Discuss my home’s backup prioritiesBackup, with clarity
Questions worth asking.
Can a battery support my air conditioning?
Requested A/C loads require review of startup demand, continuous draw, simultaneous loads and system output. The assessment confirms a suitable configuration; battery count alone is not a guarantee.
How long will backup last?
Runtime varies with your selected loads, starting charge, operating conditions and usable reserve. We plan around your priorities rather than promise a fixed duration.
Which platforms can I compare?
Tesla Powerwall 3, FranklinWH aPower 2 with aGate, and EcoFlow OCEAN Pro. Their stored energy and power architecture differ, so we review the complete configuration.
What does the system price include?
The published amounts are customer system totals for listed configurations. Your assessment and agreement confirm installation scope, permit requirements and any electrical or site-specific work.
