A Citadel system, built around your house
Why consider EcoFlow OCEAN Pro?
OCEAN Pro separates modular battery energy from system power conversion. Citadel uses that distinction to make the comparison useful: module count tells you stored energy, while inverter configuration and connected batteries determine available power. We size both around your home, not around the largest number on a specification sheet.
System-level power planning
EcoFlow advertises an inverter system with up to 24 kW continuous output. That is not a promise of 24 kW from one 10 kWh module; configuration and battery capability matter.
A coordinated design
Citadel reviews the inverter, modules, controls and priority loads together. Existing solar compatibility can be assessed separately without assuming new solar installation.
Module count, inverter configuration, placement, electrical service and backup controls are reviewed together. Final output and A/C support require manufacturer configuration guidance and a site assessment.
Standard totals by battery count
10 kWh nominal energy per module. Power output requires separate configuration review.
| Count | Energy (kWh) | System total |
|---|---|---|
| 1 | 10 | $24,500 |
| 2 | 20 | $46,000 |
| 3 | 30 | $64,000 |
| 4 | 40 | $80,000 |
| 5 | 50 | $96,000 |
Inverter system up to 24 kW; not guaranteed one-module output. 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.

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.
