Softbundle BKW EcoFlow STREAM Standard Flex

EcoFlow STREAM Standard Flex Balcony Solar System

The EcoFlow STREAM Standard Flex kit includes a STREAM microinverter, two Sunman SMF200J 200W solar panels, and all necessary cables, including PV, AC, two 3-meter MC4 solar panel extension cables, and two PowerStream MC4 flat cables. It’s an easy and convenient way to start your balcony solar journey — installation and configuration are very simple. With this kit, you can power selected appliances with solar energy and save on your electricity bills! The STREAM microinverter supports two independent MPPT channels, each with an input of up to 600W — totaling up to 1200W from PV panels. It delivers up to 800W output power at 3.48A, making it ideal for on-grid systems. You can also control it via the EcoFlow app thanks to built-in Wi-Fi and Bluetooth.

Optimized for Various Working Conditions

The EcoFlow Stream microinverter features two independent Maximum Power Point Tracking (MPPT) channels, each capable of handling up to 600W input. This enables the device to work efficiently even when panels are placed at different angles or partially shaded. Independent operation of each channel maximizes available sunlight usage and reduces energy loss caused by varying sunlight conditions. What’s more, the microinverter activates at just 3W input, allowing it to start working early in the morning and right before sunset.

Flexible Panel Compatibility

With an input voltage range of 16 to 60V DC, the microinverter is compatible with a wide range of PV panels. It works with 99% of panels available on the market and maintains high efficiency even under low sunlight conditions.

Stable Grid-Connected Power Output

The EcoFlow Stream 800W operates in an on-grid mode — the energy goes directly into the home electrical system, supporting daily consumption or feeding surplus energy back to the grid. The STREAM system can generate up to 858 kWh of energy annually, saving you up to 137 euros based on the average European electricity prices. Additionally, the microinverter operates stably over a wide grid voltage range (183–276V) and frequency range (45–65 Hz).

Intuitive App Control

Thanks to Wi-Fi and Bluetooth connectivity, you can monitor and configure the microinverter remotely using the EcoFlow app. The app provides real-time data, consumption forecasts, and AI-based functions like AI-TOU (dynamic energy rates), AI Power Prediction, and Adaptive Energy Architect. The AI assistant works 24/7 to help optimize electricity usage. Other features include a Savings Calendar and remote control of connected devices. Note: Some features require an additional premium subscription.

Easy Installation – Plug & Play

No special tools or professional assistance are needed — installation takes about 30 minutes. Thanks to the Plug & Play design, the device can be easily set up even in rental apartments without permanently altering the building structure.

Designed for Outdoor Use

The microinverter is IP67 rated, meaning it’s fully dustproof and splash-resistant. It operates reliably across a temperature range from -40°C to 65°C, making it perfect for both freezing winters and hot summers. Ideal for outdoor installations!

Quiet Operation and Compact Size

With a noise level below 20 dB, the device operates almost silently. Its dimensions of 252 × 180 × 35 mm and weight of 3.2 kg make it easy to install even in tight spaces.

High-Efficiency Solar Panels Included

The kit includes two Sunman SMF200J solar panels, each featuring 60 monocrystalline cells, offering an efficiency of 16.9% and up to 200W maximum output. Thanks to innovative eArc technology, the panels combine proven crystalline silicon performance with an ultra-thin (only 2mm) composite material. They are about 70% lighter and up to 95% thinner than traditional glass panels while maintaining high durability and resistance to damage.

Lightweight, Flexible, Durable

Each Sunman SMF200J panel weighs approximately 2.6 kg and measures 1159 × 1026 × 2 mm, making them very easy to transport. Their flexible, frameless design eliminates the need for heavy mounts or aluminum frames. You can simply adhere them directly to surfaces without drilling or damaging waterproof layers, simplifying and speeding up installation. The minimal bending radius of 0.5 m also allows installation on slightly curved surfaces. Additionally, the SMF200J model meets IEC 61215 and 61730 standards and is IP68 rated for full water and dust resistance.

Essential Cables Included

The kit comes with all the necessary cables. EcoFlow PowerStream MC4 flat cables allow you to connect solar panels to the microinverter indoors without drilling holes — simply route them through door or window gaps! Additionally, 3-meter extension cables provide flexibility during installation to ensure optimal solar exposure. AC and PV cables are also included.
