EcoFlow redefines the event boundaries of balcony solar systems — by hardware

Big or small, power everything

Go to "Accounts to 0" with 3 smart settings. From lights and routers to refrigerators and kettles, EcoFlow STREAM series devices power appliances up to 2,300 W - all powered by the sun.

Parallel mode with solar coverage up to 2300 W

• Device settings: 1 × STREAM Ultra + 1 × STREAM Ultra or STREAM AC Pro
• Connect two units with a parallel cable to power high-powered appliances such as ovens and dishwashers — they are all solar powered.
• Power output: 1,200W (primary) + 1,100W (secondary) = 2,300W total power

Distributed mode Solar coverage up to 2000 W

• Device settings: 1 × STREAM Ultra + 1 × STREAM Ultra or STREAM AC Pro
• No cable needed — simply plug each device into individual wall outlets. Solar power reaches 2,000W with support for total power up to 2,300W when needed.
• Output: 1,200W (primary) + 800W (secondary) + 300W (grid) = 2,300W total power

Single unit mode with solar cover up to 1200W

• Device settings:1 × STREAM Ultra
• One ​​device powers your everyday essentials — ideal for light operation of TVs, stoves, fans, etc.
• Output: 1,200W from one battery

Electricity goes where household appliances live

Longer runtime with scalable capacity and solar power
 

EcoFlow STREAM Ultra offers flexible expansion of the solar panel and input of photovoltaic modules with your own hands — solar panel expansion from 1.92 kWh to 11.52 kWh⁴ and PV input expansion from 2 kW (4 MPPT) to 12 kW (24 MPPT) with up to 6 devices connected. Easily connect two devices to double the capacity, or integrate with EcoFlow DELTA series batteries for even more storage.

Energy that goes where it's needed

The AI-based system monitors all connected devices in real time, ensuring that each unit receives enough solar energy to power your appliances. If the EcoFlow STREAM AC Pro system in your kitchen runs low, AI-based load balancing automatically redirects energy from neighboring units, keeping your solar-powered refrigerator running uninterrupted.

AI-TOU (dynamic electricity tariff) — every penny counts

The app matches hourly electricity rates with your usage patterns and weather forecast to optimize your savings. It automatically charges the battery during periods of low consumption and switches to stored energy when tariffs peak, helping you save up to 5% per year⁶. Manual tariff settings are also supported for full control.

Know tomorrow's sun, always one step ahead

By analyzing hyperlocal sunlight forecasts and your appliance usage patterns, the app creates a forward-looking power plan, showing which appliances to use and when. Thanks to forecast accuracy of up to 94%, your home adapts to tomorrow's sky, helping you actively reduce dependence on the grid and maximize solar energy efficiency⁷.
