Description

EcoFlow DELTA Pro Ultra portable inverter

Be prepared for unexpected emergencies, save on bills and have the confidence that your home appliances will work no matter what. The EcoFlow DELTA Pro Ultra is an inverter that, when combined with one or more batteries (sold separately), creates a powerful portable power station – a flexible and scalable power source with impressive performance that allows you to supply power to the equipment of your choice for long periods of time. With its huge output power (up to 6900 watts), photovoltaic compatibility (up to 5600 watts) and online UPS (Uninterruptible Power Supply) function, it is perfect for even the most demanding applications. It is the ideal solution for those who want to become independent from the grid or protect their home in case of an emergency! Note: the inverter works only in conjunction with a battery.

Power up to 6900 watts – will power almost anything

Thanks to X-Fusion technology, the DELTA Pro Ultra offers continuous output power of up to 6900 watts and peak power of up to 10300 watts (for up to 10 seconds) – even while charging. This means it can easily power up to several appliances with high energy demands – including washers, dryers, heat pumps or air conditioners.

Scalable up to 30 kWh – tailor the system to your needs

The inverter works in conjunction with DELTA Pro Ultra EB batteries (sold separately) – each with a capacity of 6 kWh, which translates into many hours of power for the appliances you need. Need even more energy? You can connect up to five units together, reaching a maximum of 30 kWh. Thanks to the modular design, expansion is quick and requires no specialized tools.

Create an efficient photovoltaic system – up to 5.6 kW from panels

The DELTA Pro Ultra inverter is equipped with two PV inputs – one with a low voltage of up to 150 V and the other with a high voltage of up to 450 V, which allows you to connect up to ten photovoltaic panels of 400 W each. This allows you to get impressive power from photovoltaics – up to 5,600 watts (4,000 watts + 1,600 watts). Power your devices with free energy from the sun and save on your bills! DELTA Pro Ultra is the first power station in the world to support 450V high voltage PV input.

Several ways to charge – hassle-free access to energy

The DELTA Pro Ultra system offers extremely flexible battery charging options – you can choose from several different methods that allow you to match the way energy is replenished 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 function, which allows you to switch to emergency power within 20 ms. This way you can be sure that even in the event of a sudden power outage, your appliances, such as a refrigerator or computer, will continue to work 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.

Thoughtful design and surprisingly quiet operation

The EcoFlow DELTA Pro Ultra will work well in almost any space – from a single-family home to a vacation home to travel applications. Thanks to its modular design and 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. What’s more, the DELTA Pro Ultra’s EcoFlow system works extremely quietly – at a load of less than 2,000 watts, the noise level is 0 db! And during more intensive work, the volume does not exceed 30 dB, which is about the same as a whisper. So you can easily use the station at night – it will not disturb you.

Save on your bills

The DELTA Pro Ultra system helps reduce your electricity bills 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!
