EcoFlow DELTA Pro Ultra Power Station Inverter

The EcoFlow Delta Pro Ultra offers a combination of capacity, power and reliability rarely found in a single system. Each battery module has a base capacity of 6 kWh and can be expanded up to 30 kWh per system, providing enough energy for long-term use in a wide range of applications. This makes the power station suitable as a complete home solution or as reliable storage for your own solar energy.

With an output of 6,900 W per unit, you can easily power heavy household appliances such as refrigerators, induction cooktops, air conditioners and washing machines. Even during peak consumption, the system remains stable. Thanks to the built-in UPS function, the Delta Pro Ultra switches over within 20 milliseconds in the event of a power outage, keeping connected devices running without interruption.

The Delta Pro Ultra stands out for its charging flexibility. You can choose from four methods: via the grid, solar panels (both high and low voltage), an EV charger with adapter cable (sold separately), or an existing battery storage. This ensures you always have a suitable way to recharge quickly.

A unique feature is the dual PV input, allowing you to make optimal use of solar energy:

• High-PV Input: 80–450 V, max. 15 A, up to 4,000 W

• Low-PV Input: 30–150 V, max. 15 A, up to 1,600 W

Together providing 5,600 W of solar input, enabling fast charging even under less favorable weather conditions.

The smart battery management system works together with the efficient X-Cooling system to ensure performance and safety, even during prolonged use. Below 2,000 W the system operates silently at a noise level of 0 dB, ideal for indoor use or quiet environments.

With the EcoFlow app, you stay in control of your energy supply anywhere in the world. You can monitor real-time consumption, set charging schedules and adjust settings in detail. The app also integrates with EcoFlow OASIS, an advanced energy management system that automatically makes smart decisions based on energy use, solar input and electricity rates. This way, you charge during off-peak hours, maximize your solar power and save consistently on energy costs.

The robust LFP batteries are designed for daily use, retaining more than 80% of their original capacity after 3,500 full charging cycles. This corresponds to a lifespan of about ten years under normal use. Thanks to the IP54 certification, the unit is protected against dust and splashes, making it suitable for both indoor and outdoor use. EcoFlow provides a standard five-year warranty for extra peace of mind.

With its modular design, quiet operation and high performance, the Delta Pro Ultra forms a solid foundation for any future-proof energy system.

Important: The EcoFlow DELTA Pro Ultra Power Station Inverter can only be operated in combination with at least one expansion battery.
