Marstek 1-Phase SmartBox - Backup & Connection Hub for Venus E 3.0

The Marstek SmartBox 1-Phase provides a smart backup solution for homes seeking protection against power outages. This system functions as an energy manager and an automatic emergency power switch. The device works seamlessly with the Marstek Venus E home battery. The connection ensures that critical loads like lighting and medical equipment remain operational during grid failure. The setup is designed for single-phase connections and fits the majority of residential distribution boards.

You choose a clearly designed hub with a lightweight housing. The system monitors the grid status continuously and passes through the full grid load during normal operation. The internal safeguards are arranged clearly for safe mounting on site. This hub represents a functional extension for modern installations with energy storage.

Important system configuration

The manufacturer adjusted the recommended setup for optimal stability after field testing:

  • Maximum support: the hub supports a maximum of two Venus E units.
  • Backup output: the configuration delivers a backup output power of 3.5kW to 4.0kW.

Advantages of Marstek SmartBox 1-Phase

  • Fast switchover: the system detects a mains interruption and switches to battery power within approximately 1 second.
  • Clear installation: the light enclosure and logical layout save time for the installer during mounting.
  • safe current transfer: the built-in components protect connected groups effectively against overloading.
