## Long description

EcoFlow STREAM Ultra X is a scalable home battery system designed to maximise solar energy use and reduce electricity costs. With support for parallel connection of two units and up to 2000W solar input, the system stores surplus daytime solar power for use from sunset to sunrise. Integrated hardware and software safety features combine with AI-driven energy management to optimise charging, discharging and savings across varying electricity tariffs.
Advantages
By combining two STREAM units in parallel you can reach a peak output of 2300W, enabling 100% solar operation for heavier appliances. Four MPPTs and a 2000W PV input increase solar capture efficiency, and advanced low-light technology extends daily solar harvest even under muted skies. EcoFlow OASIS AI analysis offers dynamic optimisation including tariff-aware charging to increase annual savings, while compatibility with EcoFlow Smart Meter and Smart Plug enables automatic real-time grid-matching and device-level control.
Key specifications
Parallel output (two units): up to 2300W
Battery usable capacity range: from 3.84 kWh (single configuration) scalable up to 23 kW equivalent capability
Solar input: up to 2000W via four MPPTs
Low-light harvesting: improved capture for up to ~1 extra hour daily vs industry average
AI Mode: tariff- and forecast-aware optimisation for increased annual savings (up to 29% stated)
Compatibility: EcoFlow Smart Meter, Smart Plug, and third‑party devices using Tiber, Matter, Shelly
Construction: paint-free, eco-textured unibody with interchangeable front panels (Natural Wood, Matte Black)
How to use
Install the STREAM Ultra X according to the manufacturer manual and connect solar panels to the MPPT inputs. For higher output, link two STREAM units or pair a STREAM Ultra X with STREAM Extra Batteries using the Parallel Cable. Configure EcoFlow OASIS and enable AI Mode to allow tariff-aware charging and automatic optimisation. Optionally connect EcoFlow Smart Meters or Smart Plugs for device-level control and automated grid matching. Monitor performance and system status via the EcoFlow app.
Recommendations
For best results, size your solar array and battery configuration to match typical household peak loads and local solar conditions. Use the AI Mode and Smart Meter integration to schedule low-tariff charging when forecasts predict cloudy periods. Follow official installation and safety instructions and consult a certified electrician for grid-tied setups.
