A power station that doubles as an inverter
The EcoFlow DELTA Pro Ultra pairs an inverter with a LiFePO4 battery in a single system whose capacity runs from 6 to 30 kWh. People use it as an electricity reserve for a house, as a self-contained source on a job site, or as backup power in a business premises. It recharges from the mains, from photovoltaic panels or from an electric vehicle charger, so the method can follow the situation.
Uses for households and professionals
At home
A family can keep a fridge, lighting, an internet box and a small heater running through an outage. With 5 bypass outlets and 5 discharge outputs, several circuits can be fed side by side.
On site or in the workshop
A tradesperson can plug in tools, a light compressor or area lighting. The 230 V outputs add up to 6900W on discharge, while the USB-C and USB-A ports serve phones, tablets and laptops.
Design
The battery is LiFePO4, rated for 3500 cycles to 80%. The unit measures 690 × 481 × 214 mm, weighs 32.1 kg and works from −20°C to 45°C. Wi-Fi connectivity is included.
Setting up and connecting
Place the unit on a flat, dry and stable surface with free space around it for airflow. For solar panels there are two inputs: the high-voltage input accepts 80-450V 15A and 4000W max, while the low-voltage input with a CP30 connector accepts 30-150V 15A and 1600W max. Check the voltage of your modules before linking them. Any connection to the dwelling’s electrical panel must be left to a qualified installer.

Safety
Respect the current limit of every port, use only cables sized for the intended current, and let the unit breathe. No protection rating is supplied, so keep it away from rain and damp.
Care and storage
Wipe the housing with a dry cloth. If it will sit idle for a long time, store it somewhere dry within the stated temperature range, and check the manufacturer’s manual for the recommended state of charge.
