EcoFlow DELTA 3 Max Plus Portable Power Station (082199 EFD3MP-EU-CBOX)

The EcoFlow DELTA 3 Max Plus is a portable power station designed to maintain the operation and safety of essential devices in almost any situation. It provides 3000 W of continuous power (with a 6000 W surge) and a base capacity of 2 kWh, expandable up to 10 kWh using additional batteries. With its intelligent energy-management system, multiple charging options, and UPS functionality, it ensures reliable access to electricity without fuel, noise, or stress.

Power You Can Depend On

DELTA 3 Max Plus keeps your equipment running when the grid fails. Its 3000 W continuous output and 6000 W surge capability support key household appliances such as refrigerators, lighting, kettles, and power tools. With X-Boost technology, the station can handle loads up to 3900 W. This makes it a practical solution for blackout protection and essential energy independence.

UPS Function for Reliable Backup Power

Even a short power interruption can cause data loss or equipment damage. With its built-in UPS mode, DELTA 3 Max Plus switches to backup power in under 10 ms, ensuring uninterrupted operation of computers, NAS servers, 3D printers, and security systems. HID support allows data to be saved safely and devices to shut down automatically before the battery is depleted. This guarantees smooth operation even during unexpected outages.

Flexible Capacity from 2 kWh to 10 kWh

The station adapts to your needs. You can expand the standard 2 kWh capacity up to 10 kWh using additional batteries. For even greater reliability, DELTA 3 Max can be paired with an intelligent fuel generator, ensuring extended operation during long-lasting outages.

Charging Options for Every Situation

DELTA 3 Max Plus supports several charging methods. Using an AC outlet and X-Stream technology, it charges from 0% to 80% in about 47 minutes. Solar charging of up to 1000 W (2 × 500 W) restores 80% capacity in about 1.7 hours. Charging via a vehicle alternator takes about 2 hours at up to 1000 W. Fuel-powered generator charging is also supported. With the Storm Guard feature, the EcoFlow app automatically starts charging when a severe-weather alert is detected.

Smart Energy Management with EcoFlow OASIS

The app gives you full control over your energy system. Output Priority mode lets you assign which circuits receive power first, ensuring that essential appliances such as refrigerators or lights continue to operate during an outage. Self-Powered, TOU, and Scheduled Tasks help shift charging outside of peak-price hours. PV forecasting and an AI assistant provide recommendations to optimize usage. This is more than emergency power—it is an intelligent home energy hub.

Long-Life Battery with Advanced Protection

The station uses LFP (lithium iron phosphate) battery cells, capable of maintaining full performance for up to 10 years. The ARM Cortex-based BMS monitors battery health around the clock. More than 40 protection layers safeguard against overcharging, overheating, and short circuits. AI-enhanced learning adapts charging behavior to prolong battery lifespan.

Durable Automotive-Grade Construction

The CTC (Cell-to-Chassis) structural design results in exceptional durability, resistant to shocks and pressure up to 100 kg. The device operates in various conditions, charges at temperatures as low as 0°C, and discharges down to −10°C. EMC Class B compliance ensures no interference with home electronics, while X-Quiet 3.0 technology keeps noise below 30 dB—similar to a whisper or the ticking of a clock.

Energy Independence with Eco-Friendly Operation

Combined with solar panels, the DELTA 3 Max Plus forms a fully self-sufficient system. Charge it during the day using solar power and use the stored energy at night or during grid failures. This reduces reliance on the power grid and lowers household energy costs without compromising comfort.
