EcoFlow Delta Pro 3 - Portable PowerStation Battery - 4000W - 4096 Wh/51.2V

The EcoFlow DELTA Pro 3 Power Station is a high-capacity energy storage unit designed to provide stable power in domestic, off-grid or emergency situations. With 4,096 Wh of capacity, it can power a wide range of electrical appliances for an extension.

The exterior features a sturdy finish and compact dimensions considering the power it can deliver: 693 × 341 × 410 mm. The body appears well-built, with structural elements that suggest it is also suitable for fixed installations. The unit is designed for plug-and-play use, but in cases of domestic power supply via a transfer switch, qualified intervention is required. The predominant colour is dark, with clearly legible front panels and neatly arranged connections.

From an operational point of view, it offers 4 AC outputs with a nominal power of up to 4,000 W and a peak output of up to 8,000 W. The USB-A ports allow fast charging: 5 V at 2.4 A, 9 V at 2 A, 12 V at 1.5 A (up to 18 W). Direct current outputs include a 12 V/30 A (378 W) port, a 5 A DC5521 port and a 30 A Anderson port. Solar charging is managed on two separate inputs: one high voltage (30-150 V / 15 A, up to 1,600 W) and one low voltage (11-60 V / 20 A, up to 1,000 W), for a maximum cumulative PV power of 2,600 W. Charging from the mains reaches up to 2,900 W and the device also supports charging from cars (12 V / 8 A) and 48 V systems (20 A).

The battery uses LFP (lithium iron phosphate) chemistry, known for its stability and durability. The declared life cycle is 4,000 cycles, maintaining at least 80% of capacity. The unit communicates via WI‑Fi (2.4 GHz), Bluetooth and CAN, allowing monitoring via an app. The battery-powered unit has an IP65 protective rating, making it resistant to dust and splashes. The control system includes the X‑Guard system, which monitors dozens of parameters for safety.

• 4,096 Wh capacity: allows for extended load power supply; excellent for domestic or off-grid use.
• AC outputs 4,000 W / peak 8,000 W (X‑Boost up to 6,000 W): supports appliances with high absorption.
• Dual 2,600 W photovoltaic input: accepts high and low voltage panels to optimise solar charging.
• LFP chemistry + 4,000 cycles at 80%: ensures long life with reduced stress.
• IP65 protection rating for the battery-powered pack: dust/splash resistance, suitable for controlled outdoor conditions.

The EcoFlow DELTA Pro 3 power station charging system is designed to manage multiple input power sources, optimising charging time.

The AC input from the mains is compatible with voltages from 200 to 240 V, with a maximum power consumption of 2,900 W. The system is protected by electronic controls that regulate temperature, current and voltage.

The unit is equipped with dual solar inputs with a combined power of up to 2,600 W. The first input accepts high-voltage panels (30–150 V / 15 A), with a maximum of 1,600 W.

The second input works on low voltage (11–60 V / 20 A), up to 1,000 W. The presence of two independent channels allows for flexible photovoltaic configurations.

The car input is compatible with 12 V and 48 V voltages, with absorption up to 20 A, useful during mobility.

The DELTA Pro 3 output panel includes all the interfaces needed to power AC and DC appliances:

• 4 AC sockets: 4,000 W nominal with a maximum peak of 8,000 W. Stable voltage and pure sine wave to power household appliances and professional equipment;
• 2 x 100 W USB Type-C ports: support variable 5/9/12/15/20 V output up to 5 A for charging laptops and fast-charging devices;
• 2 fast-charge USB Type-A ports: up to 18 W, compatible with Quick Charge standards for smartphones and tablets;
• 1 x 12.6 V / 30 A output: dedicated high-power Anderson port, ideal for DC systems or automotive devices;
• 1 DC5521 port: 5 A max, for small accessories.
