EcoFlow STREAM ULTRA / Solar Panel 4×400 Kit

This kit from the EcoFlow brand is an energy independence solution that combines a powerful portable power station and solar panels. This product belongs to the Energy Independence > Kits category and is designed to power household appliances using solar energy, with scalability and intelligent control capabilities.

Flexible Operating Modes and Real Capacities

The kit supports three main usage scenarios, allowing you to adapt the system to your needs:

• Parallel Mode — Solar Coverage up to 2,300 W: 1 × STREAM Ultra + 1 × STREAM Ultra or STREAM AC Pro configuration with two units connected via a parallel cable; allows powering high-power appliances (e.g., oven or dishwasher) entirely from solar energy. Output power: 1,200 W (primary) + 1,100 W (secondary) = 2,300 W.
• Distributed Mode — Solar Coverage up to 2,000 W: 1 × STREAM Ultra + 1 × STREAM Ultra or STREAM AC Pro configuration without a cable — each unit connects to a separate wall outlet; solar energy reaches 2,000 W with the ability to support a total power of up to 2,300 W when needed. Output: 1,200 W (primary) + 800 W (secondary) + 300 W (grid) = 2,300 W.
• Single Unit Mode — Solar Coverage up to 1,200 W: 1 × STREAM Ultra setup for basic needs; one device provides energy for essential daily appliances (TV, stove, fan, etc.). Single unit output: 1,200 W.

Scalability of Battery and Photovoltaic System

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

Intelligent Energy Management

The AI-powered system monitors connected devices in real-time and ensures that each unit receives sufficient solar energy for stable appliance operation. For example, if the STREAM AC Pro in the kitchen runs low, AI-based load balancing automatically redirects energy from neighboring units, ensuring uninterrupted operation of the refrigerator or other critical devices.

AI-TOU and Cost Optimization

The EcoFlow mobile app matches hourly electricity tariffs with your consumption patterns and weather forecasts, optimizing battery charging and discharging. The system automatically charges the battery during low-tariff periods and switches to stored energy during peak tariffs, allowing savings of up to 5% per year. Manual tariff settings are also available to users for full control.

Solar Energy Forecasting

Analysis of hyper-local sunlight forecasts and your usage patterns allows the app to build a prospective power plan, suggesting which appliances are best to use and when. With forecast accuracy up to 94%, your home is always one step ahead, helping to reduce reliance on the centralized grid and maximize solar energy utilization.

The kit is suitable for users who aim to reduce electricity costs and ensure reliable power for household appliances, regardless of dwelling size. The manufacturer reserves the right to change the composition, configuration, color, warranty period, and technical specifications without prior notice; technical specifications and configuration may vary.
