Four MPPT ports for maximum solar energy

Each STREAM Ultra features four independent MPPT inputs, enabling optimal use of available solar energy – even with varying roof pitches or partial shading. Combining both devices creates a storage system with a total capacity of 3.84 kWh and up to 2300 W output power – ideal for power-intensive applications, smart homes, or self-sufficient residential projects.

Intelligent energy distribution & smart control

With its integrated AI engine , the STREAM Ultra analyzes and optimizes energy flow in real time. The system learns from your consumption behavior and automatically distributes power where it's needed, thus increasing your self-consumption rate. Power is stored exactly where you need it—for example, in the basement, kitchen, or home office. The 800W safety circuit ensures maximum safety during daily operation.

Decentralized integration for maximum efficiency

The STREAM Ultra units can be installed in different areas of your home or outdoors. Decentralized storage avoids energy loss due to long cables and allows you to use your generated solar energy even more efficiently. The modular system grows with your needs and can be flexibly expanded up to 12 kWh .

Robust, space-saving & weatherproof

With an IP65 protection rating, the STREAM Ultra Set is weatherproof and suitable for both indoor and outdoor use. Its modern, compact design saves up to 50% space compared to conventional storage systems—perfect for apartments, single-family homes, or balcony complexes.
