EcoFlow's most powerful power solution for self-sufficient energy supply.
DELTA Pro Ultra (inverter + battery) offers the highest output power and capacity of all portable EcoFlow power stations. In addition to enormous energy storage and a flexible design that adapts to your needs, DELTA Pro Ultra uses solar energy to power your most important devices – even your entire household – for weeks without interruption.
- Daily use. Powerful energy for everyday life – charge your electric car, run your kitchen or enjoy entertainment on the patio – all with just one system.
- Solar storage. Generate solar power during the day and store it for later. DELTA Pro Ultra stores excess energy from your solar panels – no energy is wasted.
- Emergency power supply. During storms or power outages, DELTA Pro Ultra immediately supplies your most important appliances or your entire household.
- Commercial & industrial. Do you need mobile energy for tools, medical equipment or outdoor use? DELTA Pro Ultra delivers silent, high performance where you need it.
6–30 kWh capacity for weeks of comfort.
Experience a new level of energy reliability with a battery capacity of up to 30 kWh. For an average household, this means weeks of basic power supply – lights and important appliances such as the refrigerator remain reliably operational (duration depends on consumption). Stackable and space-saving – ideal for the garage or utility room.
A 6,900 W system effortlessly powers all your appliances.
With an output power of 6,900 W, EcoFlow DELTA Pro Ultra runs even power-intensive household appliances – even a charging station for electric vehicles. Thanks to X-Fusion technology, the power remains constant at 6,900 W even during charging.
5 ways to fast charge – ready for use at any time.
With the versatile charging options of EcoFlow DELTA Pro Ultra, you are always flexible. In addition to proven options such as solar or mains power, the system can also be charged via a petrol generator or an EV charging station. Thanks to an industry-leading charging speed of 8,800 W, two batteries can be fully charged in just 2 hours.
Round-the-clock energy management with EcoFlow OASIS.
Take it anywhere. The trolley makes DELTA Pro Ultra easy to transport, whether outdoors or when moving house. Portability refers exclusively to setups with a single battery. Configurations with multiple batteries are intended for stationary use.
Backup – so quiet you hardly notice it.
Thanks to EcoFlow DELTA Pro Ultra's UPS, sensitive devices remain reliably protected – and almost silently. In the event of a power failure, the system takes over in just 20 ms and remains virtually inaudible at power levels below 2,000 W with a whisper-quiet 0 dB – ideal for the home office or a quiet night.
Greater safety thanks to advanced design.
- Inverter. With a flexible plug-and-play design and exceptional solar input, EcoFlow DELTA Pro Ultra adapts precisely to your energy needs. The integrated PV lock provides additional safety and a stable connection.
- Battery. Modern LFP technology and an advanced battery management system (BMS) monitor all important data and guarantee the safety, durability and consistent performance of EcoFlow DELTA Pro Ultra. Each battery achieves over 3,500 charging cycles – after which you still have 80% capacity available. And even then, it continues to deliver reliable power.
Reliable power – even under extreme conditions.
EcoFlow DELTA Pro Ultra proves itself even in the toughest challenges. Whether extreme weather or freezing cold – this powerhouse ensures your power supply at all times.
