EcoFlow Delta Pro Ultra

The EcoFlow Delta Pro Ultra is a whole-home backup power system featuring a massive 6kWh capacity per unit, expandable up to 90kWh for extended off-grid capability. The system delivers 7.2kW to 21.6kW output depending on configuration, compatible with both 120V and 240V electrical systems. LiFePO4 (LFP) battery chemistry provides 3,500+ cycles before capacity drops to 80%, ensuring years of reliable service with the included 5-year warranty.

The Smart Home Panel 2 integration enables automatic switchover in just 20 milliseconds during power outages, maintaining uninterrupted power for critical appliances. Through the panel, you can customize which of up to 12 circuits receive backup power and set priorities—keeping refrigerators and medical equipment running while limiting non-essentials. The EcoFlow app provides real-time monitoring, scheduling, AI-powered optimization that analyzes usage patterns, and 4G dongle connectivity for control even when WiFi is down.

Versatile charging options include 5.6kW solar input per inverter (16.8kW with three inverters), EV charging stations via the X-Stream Adapter at 7,200W, wall outlets, and generators. The inverter includes four 120V AC outlets, 30A RV outlet, 240V heavy appliance outlet, USB-A and USB-C ports, and DC output. Full charge completes in just 2 hours. The system qualifies for the 30% federal clean energy tax credit, significantly offsetting the initial investment. Bluetooth 4.2/5.0 connectivity supports local control when internet is unavailable.
