A 6144 Wh energy reserve you can move around
EcoFlow’s DELTA Pro Ultra pairs an inverter with a 6144 Wh LiFePO4 battery in a portable power station. It is meant for people who want to run several devices at once: building-site tools, the appliances of a motorhome, workshop equipment or home back-up during an outage. Its job is to store energy, deliver it as alternating or direct current, and recharge from the mains, from solar panels or from an electric-vehicle charging point.
Use cases
At home and on the move
A homeowner can consider it as back-up during a fault or paired with panels to reduce use of the grid. Travellers in a motorhome or on a boat will see a way to power the galley, lighting and chargers.
For professionals
Tradespeople, event organisers and technical crews can power tools and lights where the grid is absent. Always check the power draw of each device before connecting it.
Ports and capacities
The 230 V output delivers 6900 W in total at 50 Hz, spread across four 16 A sockets and one 30 A socket. Bypass mode is given as 220-240 V, 50/60 Hz, 2900 W in total, on five 12,5 A sockets. There are also two 100 W USB-C ports (200 W in total), two 12 W USB-A ports (24 W in total) and a DC output of 12,6 V, 30 A, 378 W max.
Recharging and set-up
- From the mains: roughly 2,6 hours with 2800 W on a 230 V Schuko outlet, according to the data sheet.
- With a 6900 W electric-vehicle charger: roughly 1 hour.
- From solar: High-PV input from 80 to 450 V, 15 A, 4000 W max; Low-PV input via a CP30 connector, from 30 to 150 V, 15 A, 1600 W max.
The station operates from −20°C to 45°C. Place it on a flat, stable surface with space around it. Linking it to a house’s electrical panel must be left to a qualified installer.
Strengths
- A 6144 Wh capacity for heavy loads.
- LiFePO4 chemistry stated for 3500 cycles at 80%.
- Two solar inputs with distinct voltage ranges.
- Wi-Fi control, useful for keeping an eye on the unit remotely.

Safety
With this much energy, caution is needed: never exceed the per-socket ratings, use cables sized for the current and unroll them fully. Do not cover the unit, keep it dry and do not use it after a visible impact or an odd smell. Get help lifting it.
Care and storage
Dust the vents with a dry cloth. For long storage, keep the station at a medium charge level, in a dry place and within the stated temperature range, and consult the manufacturer’s manual.
