EcoFlow Redefines Balcony Solar System Limits — with Hardware

Big or Small — Power for Everything

Achieve "Bills to 0" with the kit's three smart operating modes. From lamps and routers to refrigerators and appliances, the EcoFlow STREAM series can power loads up to 2,300W, using solar energy as the primary power source.

Parallel Mode with up to 2,300W Solar Coverage

• Device setup: 1 × STREAM Ultra + 1 × STREAM Ultra or STREAM AC Pro.
• Connect two units with a parallel cable to power high-wattage appliances like ovens or dishwashers; all can be powered by solar panels.
• Output power: 1,200W (main) + 1,100W (additional) = 2,300W total power.

Distributed Mode — up to 2,000W Solar Coverage

• Device setup: 1 × STREAM Ultra + 1 × STREAM Ultra or STREAM AC Pro.
• No cable needed — connect each unit to separate wall outlets. Solar power can reach 2,000W with the ability to support a total power of up to 2,300W when needed.
• Output: 1,200W (main) + 800W (additional) + 300W (grid) = 2,300W total power.

Single Unit Mode with up to 1,200W Solar Coverage

• Device setup: 1 × STREAM Ultra.
• One unit provides energy for daily essential appliances — ideal for TVs, stoves, fans, etc.
• Output: 1,200W from a single unit.

Electricity Goes Where Appliances Live

Longer Runtime with Scalable Capacity and Solar Power

EcoFlow STREAM Ultra offers flexible DIY battery capacity and PV input expansion: battery capacity expansion from 1.92 kWh to 11.52 kWh, and PV input expansion from 2 kW (4 MPPT) to 12 kW (24 MPPT) with support for connecting up to 6 devices. Easily connect two devices to double the capacity, or integrate the system with EcoFlow DELTA series batteries for even greater energy storage.

Energy That Goes Where It's Needed

The AI-powered system monitors connected appliances in real-time and ensures that each unit receives enough solar energy for uninterrupted operation. If, for example, the STREAM AC Pro unit in the kitchen runs low, AI-based load balancing automatically redirects energy from nearby units to keep the refrigerator and other critical appliances running on solar power.

AI-TOU (Dynamic Electricity Tariff) — Every Penny Counts

The mobile app matches hourly electricity tariffs with your consumption profiles and weather forecast, optimizing battery charge and discharge. The system automatically charges the battery during low-tariff periods and switches to stored energy during peak hours, saving up to 5% annually. Manual tariff settings are also available for users to have full control over system operation.

Solar Energy Forecast — Always a Step Ahead

By analyzing hyper-local solar radiation forecasts and your appliance usage patterns, the app creates a predictive power plan, suggesting which appliances are best to use and when. With forecast accuracy up to 94%, your home adapts to the next day's weather conditions, helping to reduce grid dependence and increase solar generation efficiency.
