Product description
The EcoFlow DELTA Pro Ultra is a modular whole-home backup system. A 6900W inverter pairs with one to five 6144Wh LFP batteries, giving you 6kWh to 30kWh of storage behind a single 230V output for the house, sheds and workshop.
Choose a complete system with one to five batteries, or buy the inverter or extra batteries on their own to build or expand a setup.
One inverter accepts up to 5.6kW of solar across separate High-PV and Low-PV inputs. Combined with mains or generator charging, input reaches 8800W, recharging a battery to 80% in 1 hour 13 minutes.
When the grid drops out, switchover takes under 20 ms, and loads under 2000W run silently for up to 30 minutes. Self-heating batteries, IP54 protection and a -20°C to 45°C operating range suit sheds and garages. Bluetooth, Wi-Fi and 4G connect it to the EcoFlow app.
