EcoFlow DELTA Pro Ultra X Inverter

Commercial & Home Backup Inverter — 12kW to 36kW Split-Phase Output

EcoFlow

The EcoFlow DELTA Pro Ultra X Inverter is engineered to anchor whole-home power systems, off-grid cabins, and light commercial setups. Delivering a continuous 12kW split-phase (120V/240V) output on a single unit, it scales seamlessly up to 36kW with three stacked units.

Built with true online UPS technology, 10kW dual-port high-voltage solar harvesting, an IP54 weather-resistant chassis, and ultra-quiet cooling under 30 dB, the Ultra X sets a new benchmark in flexible, high-demand energy storage.

Key Highlights

Massive 12kW to 36kW Output: Delivers 12,000W of split-phase 120V/240V power out of a single inverter, expandable up to 36kW by paralleling 3 units.
10kW High-Voltage Dual Solar Input: Dual PV ports handle up to 5,000W each (80–500V / 15A), scaling up to 30,000W total array input across 3 units.
Seamless Online UPS (<10ms): Instantaneous sub-10ms transfer time keeps sensitive electronics, water pumps, refrigeration, and medical devices running without a flicker.
Ultra-Quiet Whisper Operation: Advanced cooling architecture operates below 30 dB at 0.5m (at 4kW load), ensuring quiet indoor mechanical room performance.
Heavy-Duty AC Receptacles: Built-in panel includes dual NEMA 5-20 (120V 20A), NEMA L14-30 (120V/240V 30A), and high-output NEMA 14-50 (120V/240V 50A) ports.
Modular Storage Architecture: Stacks with EcoFlow 6.14kWh LFP battery modules—from 12.3kWh up to 61.4kWh per inverter, and up to 184.3kWh in a 3-unit system.
