The EcoFlow Delta Pro Ultra, previously only available on the US market, is now officially coming to Germany and boasts impressive technical values. With a continuous output of 6,900 watts, a base capacity of 6 kWh and the option to expand to up to 30 kWh, the power station is clearly aimed at technology enthusiasts and demanding users. The combination of high performance, versatility and smart control makes the Delta Pro Ultra one of the most exciting products in the mobile energy storage sector.
Highlights
- 6,900 watts continuous output – currently the most powerful power station in Europe
- 6 kWh capacity, modularly expandable to 30 kWh
- Extremely robust design: LFP battery, IP54 protection, use from -20 °C to +45 °C
- Five charging options including solar with up to 5,600 watts
High performance for demanding applications
The Powerstation sets new standards in its class and is likely to generate a great deal of interest, particularly in the areas of emergency power supply, mobile working, outdoor activities and in combination with solar systems.
The device uses long-life lithium iron phosphate cells (LiFePO4), which are not only more temperature-resistant, but also have a significantly longer service life than conventional lithium-ion batteries. Despite its performance, it is surprisingly versatile: at low load, it runs completely silently – a decisive advantage at events, in the home office or when camping.
Robust design for outdoor and emergency use
EcoFlow has also placed particular emphasis on high resistance. With a protection class of IP54, the Delta Pro Ultra is protected against dust and splash water and is therefore predestined for outdoor use. The device can be operated at temperatures as low as -20 °C, which is particularly important for winter use.
At the same time, the output voltage is stable at up to 290 volts – so even sensitive electronics are well protected. The integrated online UPS function (uninterruptible power supply) is also particularly noteworthy from a technical point of view: In the event of a power failure, the power station automatically switches to battery operation in under 20 milliseconds – a safety net for servers, gaming PCs or home office workstations.
Flexible charging system with record values
Another highlight is the charging system. In addition to conventional mains power, the power station can be supplied with up to 5,600 watts via solar panels – a record value in the mobile sector. EcoFlow combines five types of charging here: household electricity, solar charging, EV charging station (via optional PowerPulse adapter), gas generator and manual disconnection for feeding into the household grid.
This flexibility makes the system suitable for off-grid applications as well as a backup for existing energy infrastructures. In combination, the Powerstation reaches a charge level of 80 percent within around 73 minutes – remarkable for a device of this size.
Smart control and modular expandability
Numerous settings can be made via the associated EcoFlow app, including charging limits, time control and prioritization of certain power sources. A so-called self-sufficiency mode also allows excess solar energy to be stored or fed into the grid. The modular expandability – with additional 6 kWh battery modules – enables expansion in line with demand. In an emergency, a detached house can be supplied with electricity for several hours or even days, depending on consumption and capacity expansion.
