S-FLOW

TENED S-FLOW is a professional 48 V sodium-ion energy storage module engineered for thermal stability, predictable lifetime behavior, and long-term operational reliability.

The polyanionic sodium-ion chemistry (NFPP) provides a low intrinsic thermal risk and stable performance across a wide temperature range, supporting safe indoor installation.

Highlights

Safe sodium-ion chemistry
for indoor technical environments

Protection layer
Professional BMS supervision and

48 V building blocks
for DC and small hybrid systems

Predictable performance
across wide temperature range

High Performance, Flexibility and Versatility

Each module integrates a professional BMS for voltage, current, and temperature supervision, protection against abnormal conditions, and controlled reconnection within safe limits.

System integration is supported via CAN bus and RS485, enabling compatibility with external energy anagement systems without closed ecosystem dependency.

The design features a 48 V modular architecture, industrial metal enclosure, fixed electrical connections, and a compact form factor optimized for technical rooms.

Indoor installation is supported using standard electrical safety measures, subject to local regulations.

Enhanced Safety: NFPP chemistry is inherently safe and does not support thermal runaway, effectively preventing fires or explosions.

No special fire suppression systems are required beyond standard electrical safety measures, subject to lo cal regulations and project-specific risk assessment.

Applications: residential and small commercial ESS, backup and emergency power, self-consumption and load support, fixed 48V DC systems, and projects where lithium-ion is restricted or less suitable. Supports cyclic and stand-by operation.
