EcoFlow DELTA 3 Ultra Plus Power Station

The EcoFlow DELTA 3 Ultra Plus is an advanced power station that provides a reliable source of power during power outages, as well as while traveling, working on the go, or for everyday use at home. It offers an output power of up to 3600 W and a peak power of 7200 W, allowing it to easily power demanding home appliances, power tools, or electronic devices. The system can be expanded from 3 kWh to as much as 11 kWh, allowing you to tailor it to your needs—from emergency power for essential devices to hours of operation for your entire home infrastructure. The station supports 4 charging modes, operates in UPS mode with a switchover time of less than 10 ms, and integrates with the EcoFlow OASIS platform, which offers smart energy management features, including weather alerts and automation. Additional advantages include exceptionally quiet operation (below 30 dB), an intelligent BMS system with over 40 safety features, and a mobile design with integrated wheels and a handle.

Power to Power Home and Professional Appliances

The DELTA 3 Ultra Plus was designed for users who need high power and complete energy independence. A continuous AC output of 3600 W allows you to easily power refrigerators, electric ovens, microwaves, dishwashers, washing machines, dryers, and garment steamers. X-Boost mode increases the station’s capacity to up to 4,700 W, and the 7,200 W peak power allows you to safely start devices that require high power consumption at startup. As a result, the station is ideal not only as an emergency power source at home, but also when working on construction sites, in workshops, on film sets, or in a camper. The mobile design with integrated wheels makes transport easy, even when frequently moving the unit between locations.

Smart energy management and device priority power supply

The EcoFlow DELTA 3 Ultra Plus offers an advanced energy management system that helps extend the runtime of critical devices during a power outage. The four AC outlets are divided into two independently controlled zones that can be turned on or off separately via both the device panel and the app. This allows you, for example, to turn off the microwave or other less essential devices while keeping the refrigerator running. The station is also equipped with an Output Priority feature, allowing one of the AC outputs to operate as a priority. If power consumption exceeds the system’s limit, the remaining outlets will automatically shut off to maintain power to the most critical equipment—such as medical devices. This solution reduces energy loss, extends runtime, and additionally protects the system from overload.

UPS Function and Data Security

Sudden power outages can lead to data loss or damage to electronic equipment. The EcoFlow DELTA 3 Ultra Plus supports a UPS function that automatically switches to emergency power in less than 10 ms—without the need for manual intervention. This makes the station ideal for protecting computers, NAS servers, network devices, entertainment systems, and precision electronic equipment. It also allows for the continuous operation of CPAP devices, which can be crucial during nighttime power outages. An extensive set of ports further enhances the device’s functionality. Users have access to a 30A Anderson output, a 12V 10A car port, a 140W USB-C port, two USB-C ports with a maximum combined power of 45W, and an 18W USB-A port, enabling the simultaneous powering of a wide variety of devices.

Expandable up to 11 kWh and flexible operation

The system’s base capacity is 3072 Wh, but the DELTA 3 Ultra Plus is designed for expansion. By using additional DP3 EB batteries and the EcoFlow Smart Extra Battery Expansion Adapter, you can increase the total capacity up to 11 kWh. This solution is ideal during prolonged power outages, off-grid operations, or as a backup power source for a single-family home. The system’s flexible design allows you to tailor the configuration to your current needs—from briefly powering essential devices to providing hours of power for your entire home.

Multiple charging methods and quick setup

The EcoFlow DELTA 3 Ultra Plus portable power station supports four charging methods, allowing you to get it ready for use in virtually any situation. X-Stream technology enables fast charging from an AC outlet, allowing you to quickly recharge before a trip or an approaching storm. The device also supports solar charging with up to 1600 W via two MPPT ports, providing greater flexibility when setting up a solar power system. It is also possible to charge using a car alternator with a power of up to 1000 W and to work with power generators (including those from other manufacturers). The Smart Generator Auto Start/Stop feature enables the automatic starting and stopping of the generator depending on the battery charge level, ensuring uninterrupted power even in demanding conditions.

EcoFlow OASIS – Smart Energy Management Hub

The EcoFlow OASIS platform offers extensive automation features. The app allows you to monitor battery charge levels, the amount of energy harvested from solar panels, financial savings, weather forecasts, and current energy rates. The emergency power priority feature allows you to redirect remaining energy to the most important devices with a single click, extending their runtime by up to 32 hours for a refrigerator and other appliances. The system can also automatically shut down less critical circuits, protecting key devices from power loss. Storm protection mode monitors weather alerts and automatically initiates AC charging before a storm or weather hazard arrives. Charging and discharging schedules are also available, along with an energy independence mode that limits power draw from the grid and smart AI recommendations that analyze energy consumption and predict solar panel output based on local weather conditions. As a result, the system helps reduce electricity bills and make even better use of renewable energy.

Advanced BMS and readiness for harsh conditions

The intelligent BMS system, based on a high-performance ARM Cortex chipset, monitors key battery operating parameters around the clock. The system ensures safety, operational stability, and optimal energy management. Over 40 safety features have been implemented to protect against overheating, overcharging, short circuits, and voltage imbalances, among other issues. The EcoFlow DELTA 3 Ultra Plus uses a durable LFP battery with a lifespan of approximately 10 years. The automotive-grade CTC construction increases resistance to shocks and drops from up to 0.2 m, and the unit can withstand a surface load of up to 100 kg. The station can operate at discharge temperatures as low as -10°C, charge in the range of 0 to 45°C, and is designed to function in humid environments with humidity levels between 20 and 95% RH. It has also passed a 5% NaCl salt spray resistance test, so it will perform well even in coastal locations. Class B EMC certification ensures that the device does not interfere with TVs, Wi-Fi networks, and other home electronics.

Exceptionally quiet operation and convenience for everyday use

Despite its high power output, the EcoFlow DELTA 3 Ultra Plus operates exceptionally quietly. X-Quiet 3.0 cooling technology keeps noise levels below 30 dB during operation, ensuring the power station does not disrupt daily household activities. You can easily use it in the bedroom, RV, office, or while working at night. The mobile design with wheels and a handle makes transport significantly easier, so you can take it with you whenever needed.
