EcoFlow STREAM ULTRA 2/AC PRO 3/Solar Panel 4*400 Kit

Manufacturer: EcoFlow. Category: Energy Independence > Kits. This kit combines STREAM series portable power stations with four 400W solar panels each to provide a flexible and scalable power source for home or small business.

Three Smart Power Modes

The kit supports three key operating modes that optimize solar energy use and reduce electricity costs:

• Parallel Mode (solar coverage up to 2,300W): 1 × STREAM Ultra + 1 × STREAM Ultra or STREAM AC Pro configuration; connecting two units with a parallel cable provides solar power for high-consumption appliances (ovens, dishwashers); total output power: 1,200W (primary) + 1,100W (secondary) = 2,300W.
• Distributed Mode (solar coverage up to 2,000W): 1 × STREAM Ultra + 1 × STREAM Ultra or STREAM AC Pro configuration without the need for a parallel cable — each unit connects to a separate outlet; solar power can reach 2,000W with support for up to 2,300W in peak situations; output in this configuration: 1,200W (primary) + 800W (secondary) + 300W (grid) = 2,300W total power.
• Single Unit Mode (solar coverage up to 1,200W): 1 × STREAM Ultra configuration, providing 1,200W output power for daily essential appliances — TVs, stoves, fans, and other low to medium power devices.

Scalable Capacity and Solar Input

EcoFlow STREAM Ultra offers battery expansion from 1.92 kWh to 11.52 kWh and the ability to scale photovoltaic input from 2 kW (4 MPPT) to 12 kW (24 MPPT) with up to 6 devices connected. Easily combine two devices to double capacity or integrate the system with EcoFlow DELTA series batteries for even greater energy storage.

Intelligent Energy Management

The AI-powered system monitors all connected devices in real time, balancing the load between units and prioritizing power for critical appliances. If one unit (e.g., STREAM AC Pro in the kitchen) runs low, the AI automatically redirects power from neighboring units for uninterrupted operation of the refrigerator or other critical consumers.

AI-TOU — Tariff Optimization and Savings

The mobile app synchronizes hourly electricity tariffs with your consumption patterns and weather forecasts, automatically charging the battery during low-tariff periods and switching to stored energy during peak hours — this allows for savings of up to 5% per year. Manual tariff settings are also available for full control over the charge/discharge strategy.

Forecasting and Planning

The app analyzes hyper-local sunlight forecasts and your usage patterns, creating a power plan with up to 94% prediction accuracy — you see which appliances to turn on and when to maximize solar energy use and reduce grid dependence.

The kit includes four 400W solar panels (Solar Panel 4*400), compatible with the system's photovoltaic inputs, and allows for autonomous or hybrid power for a private home, dacha, or small office.
