EcoFlow DELTA Pro ULTRA Inverter — Power and Reliability from EcoFlow

The EcoFlow DELTA Pro ULTRA Inverter from EcoFlow is a modular power system in the Energy Independence > Inverters category, combining high output power, large battery capacity, and multi-variant charging methods. A single unit provides a stable output of 6,900W, effortlessly powering all household appliances, including energy-intensive devices and EV charging stations.

Power and Capacity

The system delivers 6,900W of output power thanks to X-Fusion technology, which ensures constant power during charging. Battery capacity is scalable from 6 to 30 kWh, providing weeks of basic power supply for an average household: lights, refrigerator, and other essential appliances will remain operational depending on actual consumption. The design is compact and stackable — convenient for a garage or utility room.

Fast and Flexible Charging

The EcoFlow DELTA Pro ULTRA supports 5 charging methods: from solar panels, grid power, a gasoline generator, an EV charging station, and alternative sources. A maximum charging speed of up to 8,800W allows two batteries to be fully charged in approximately 2 hours, making the system ready for use almost anytime.

Reliability, Safety, and Silent Operation

The system operates as a UPS with a switching time of just 20ms — ensuring uninterrupted operation of sensitive devices. At power levels below 2,000W, the device operates almost silently (0 dB), suitable for working from home or during sleep. Advanced LFP cell technology and a sophisticated Battery Management System (BMS) monitor key parameters for safety and long service life.

Each battery provides over 3,500 charging cycles while retaining approximately 80% of its initial capacity after this lifespan, after which the battery continues to provide reliable power. The advanced X-Cooling system and optimized management via BMS ensure stable operation under various loads.
