EcoFlow DELTA Pro Ultra Power Station (Inverter + 3x Battery)

The EcoFlow DELTA Pro Ultra Power Station (Inverter + 3× Battery) forms the complete foundation of the DELTA Pro Ultra system. This bundle combines the powerful inverter with two battery modules for a total capacity of 18 kWh, giving you a full-fledged energy storage system that can handle heavy loads and provides ample reserve capacity for extended use. Thanks to its modular design, the system can easily be expanded later with up to five batteries, offering a total storage capacity of 30 kWh. This allows you to tailor the setup to your energy consumption and future needs.

With a continuous output of 6,900 W per unit, it effortlessly powers multiple high-demand household appliances such as refrigerators, cooktops, air conditioners and washing machines. Peak loads are handled just as smoothly. The built-in UPS function switches over in 20 milliseconds during a power outage, ensuring sensitive devices such as computers continue running without interruption.

You have several charging options: from the grid, via solar panels (both high- and low-voltage), through an EV charger using an optional adapter cable, or from an existing battery system. With its dual PV input, the system makes optimal use of solar energy, up to 4,000 W via high-PV and 1,600 W via low-PV, for a combined total of 5,600 W of solar charging power. This enables fast and efficient charging even under less-than-ideal weather conditions.

The robust LFP batteries are built for long-term, reliable performance. After 3,500 charging cycles, they still retain more than 80 % of their original capacity, equivalent to around ten years of daily use. The advanced Battery Management System (BMS), efficient X-Cooling technology, and IP54 protection against dust and splashing water make the system suitable for both indoor and outdoor installation.

With the EcoFlow app, you’re always in control. Monitor your energy consumption in real time, manage charging times flexibly and take advantage of the intelligent OASIS integration, which automatically responds to your usage patterns, solar generation and energy prices. This way, you use solar energy more efficiently while saving on electricity costs.

With its 18 kWh capacity, high power reserves and modular expandability, the EcoFlow DELTA Pro Ultra Power Station (Inverter + 3× Battery) provides a robust, future-ready energy solution, designed to grow with your home and energy needs.
