EcoFlow DELTA Pro Ultra X Whole-Home Backup Power

Complete ESS Energy Storage System — 12kW Output | 12.3kWh Base Storage

EcoFlow

The EcoFlow DELTA Pro Ultra X Whole-Home Backup system delivers a heavy-duty, plug-and-play energy core for demanding residences, rural homesteads, and off-grid properties. Combining one Ultra X 12kW split-phase inverter with two 6.14kWh LFP Smart Extra Batteries, this base package establishes 12.3kWh of continuous backup power right out of the box.

Engineered with true online UPS transfer times (<10ms standalone), a 10kW dual-port high-voltage solar MPPT controller, IP54 weatherproofing, and whisper-quiet cooling under 30 dB, the Ultra X provides seamless, self-reliant energy security during grid outages or off-grid operation.

Whole-Home Grid Integration Notice: Direct hardwired whole-home panel integration requires the EcoFlow Smart Home Panel 3 and Smart Gateway (sold separately). Please note that the Smart Home Panel 3 and Smart Gateway are not currently available in Canada. For Canadian setups, the DELTA Pro Ultra X operates via its heavy-duty onboard receptacles (including NEMA 14-50 50A and L14-30 30A) or through an approved manual transfer switch / generator inlet.

Key Highlights

12kW Continuous Split-Phase Power: Supplies continuous 120V/240V power out of a single unit, easily running central A/C units, well pumps, heaters, and heavy workshop equipment.
12.3kWh Expandable LFP Capacity: Includes two 6.14kWh LFP battery modules (12,288Wh total). Expandable up to 61.4kWh with one inverter (10 batteries) or up to 184.3kWh across 3 paralleled inverters.
Massive 10kW Dual Solar Input: Dual high-voltage MPPT ports accept up to 5,000W each (80–500V / 15A), scaling up to 30,000W of total solar harvest on a 3-inverter stack.
Sub-10ms Online UPS Transfer: Instantaneous auto-switchover keeps sensitive electronics, medical equipment, and refrigeration operating without interruption.
Heavy-Duty AC Receptacle Panel: Includes built-in NEMA 14-50 (120V/240V 50A), NEMA L14-30 (120V/240V 30A), and dual NEMA 5-20 (120V 20A) outlets.
Ultra-Quiet Whisper Cooling: Operates at under 30 dB (at 0.5m under 4kW load), ensuring whisper-quiet operation in utility rooms or home environments.
