Two units for plug-and-play solar storage
This bundle pairs two EcoFlow STREAM Ultra X units to reach 7.68 kWh, each contributing 3.84 kWh and able to be expanded up to 23 kWh. The device works in plug-and-play mode: it links to a 230V outlet and to an EcoFlow or Shelly smart meter instead of requiring complex wiring. Solar panels connect to it directly through four internal MPPT inputs.
Who it is for
A home with solar panels
A house whose solar output exceeds the day’s consumption can build up the surplus here. The device then sends energy back onto a grid-connected circuit, up to 1,200 W when that circuit is dedicated.
A professional site
A small farm or workshop that works mostly by day can shift part of its consumption. A noise level of 30 dB allows it to sit in a working space without bother.
Design and construction
Each unit measures 42 x 29.4 x 46 cm and weighs 38.8 kg. The IP65 rating protects against dust and water jets, and the temperature range of −20 °C to +55 °C covers winter and summer alike. Connectivity relies on Wifi and Bluetooth.
Connection and setup
- Place each unit on a level support that carries 38.8 kg.
- Check the voltage of your modules: the MPPT range is 15-60 V.
- Connect the panels to the inputs without exceeding 500W or 14A (20A Isc) per input.
- Plug the device into a 230V outlet and fit the smart meter as described in the manual.
The compliance of the electrical installation, notably the question of the dedicated circuit, is a matter for a qualified electrician; also consult the manufacturer’s manual on the output power to observe.
Strengths of the model
- Four independent MPPT inputs of 500W each.
- 3.84 kWh per unit, expandable up to 23 kWh.
- Operation at 30 dB.
- Stated dust and water resistance with the IP65 rating.

Safety
Respect the current and voltage values of each input, use only suitable connectors and cables, and do not cover the housings. With the power off, let the device cool before moving it.
Care and storage
Dust with a dry cloth and check the tightness of the connectors from time to time. For a long shutdown, store the units away from damp, within the stated temperature range.
