EcoFlow DELTA Pro Ultra Rechargeable Battery
Rechargeable battery for EcoFlow DELTA Pro Ultra
Be prepared for unexpected emergencies, save on your bills, and be confident that the appliances in your home will work no matter what. The EcoFlow DELTA Pro Ultra EB is a powerful battery unit designed for next-generation power systems. Combined with an inverter (sold separately), it creates a flexible and scalable energy source with impressive performance - allowing you to power your chosen equipment for a very long time. The battery itself offers a capacity of 6 kWh, which can be expanded up to 30 kWh. This is ideal for those who want to become independent of the grid or protect their home in case of power outages! Note: the battery works only in conjunction with an inverter.
Scalable up to 30 kWh - tailor the system to your needs
Each DELTA Pro Ultra EB battery has a capacity of 6 kWh, which translates into many hours of power for the appliances you need. Need even more energy? You can link up to five units together, reaching a maximum of 30 kWh. Thanks to its modular design, expansion is quick and requires no specialized tools.
Several ways to charge - hassle-free access to energy
The EcoFlow DELTA Pro Ultra offers extremely flexible charging options - you can choose from several different methods that allow you to match the way you replenish energy to current conditions. You can use photovoltaic panels in (up to 4,000 watts or up to 1,600 watts), an electric vehicle charging station (up to 6,900 watts), a power generator (up to 2,800 watts) or a standard wall outlet (up to 2,800 watts). In addition, simultaneous charging from two sources (PV + grid) is possible, giving an impressive maximum input power of up to 8800 W. You also don't have to wait too long for the system to be ready for operation. It only takes about 1 hour and 13 minutes to charge one battery to 80%, and two batteries can recover 100% in as little as 2 hours.
Simple connection to home installation
Combined with a separately available switch (MTS - Manual Transfer Switch), the DELTA Pro Ultra can power an entire home installation. The accessory makes it easy to switch between the power grid and the EcoFlow system, making it possible, for example, to use solar energy stored during the day to power the entire house in the evening and at night and save on bills. Such a solution will also work well in emergency situations.
UPS emergency power supply
An unexpected failure? You don't have to worry about it anymore - the DELTA Pro Ultra station (battery with inverter) supports the online UPS (Uninterruptible Power Supply) function, which allows you to switch to emergency power within 20 ms. This ensures that even in the event of a sudden power outage, your appliances, such as your refrigerator or computer, will run uninterrupted!
Full control with the EcoFlow app
Convenient operation of the station is made possible by the EcoFlow app. It gives you full control over the flow of energy - real-time monitoring of consumption, charge level and much more. The intuitive interface allows you to automate charging and discharging schedules, customize operating modes and optimize the performance of the entire system. The app is also compatible with other brands such as Google, Shelly, Tapo and Kasa Smart.
All-weather readiness
The EcoFlow DELTA Pro Ultra station will perform well even in extremely demanding conditions. It offers an auto-heating function, so it's not intimidated by freezing temperatures - it can easily operate in temperatures from -20°C to 45°C. It also has an X-Cooling system and is distinguished by its IP54 rating. Dust or splashes are no threat to it! In addition, the high-end LFP (Lithium Iron Phosphate) battery has a long life, and its excellent condition is taken care of by the BMS (Battery Management System) and SOC (State of Charge) cell balancing technology.
Surprisingly quiet operation
Although it hides enormous power, the DELTA Pro Ultra's EcoFlow system operates extremely quietly - with a load of less than 2,000 watts, the noise level is 0 db! So you can easily use it while working or at night - it will not disturb you.
Thoughtful design
The EcoFlow DELTA Pro Ultra is a well-designed solution that will work in almost any space - from a single-family home to a vacation home to travel applications. Thanks to its modular design and a separately available transport cart, you can easily move the station and take it on vacation, to the garage or garden. It will also be great for professional use - for example, in offices, on film sets or at events. It's ready to serve you, wherever you need it!
Save on your bills
As part of a smart power system, the DELTA Pro Ultra EB battery helps to reduce your electricity bill in real terms. The self-powered mode allows you to use energy from solar panels first, and only later reach for power from the grid. It's also worth taking advantage of charging and discharging schedules. All of this makes it easier to reduce your power consumption from the grid and save on your bills!
