HUAWEI Back Up Box B1 - for M1 Series Inverters

Description

Huawei Backup Box B1

Backup power module for three-phase inverters of the Huawei M1 series.
The Backup Box B1 is used in rooftop PV systems to control the grid-connected and off-grid status of three-phase inverters of the Huawei M1 series.
In the event of a grid failure, the inverter switches to off-grid operation and supplies loads not connected to the grid with power in backup mode.
When the grid failure has been resolved, the inverter switches back to the grid-connected state. The Backup Box B1 supports the following grid systems: TN-S / TN-C-S / TT.
When installing the Backup Box B1 outdoors, avoid exposing it to direct sunlight.
It is recommended to install it in a sheltered place or to fit it with a cover. In the circuit of the Backup Box B1, an SPD surge protection device must be installed on the grid side.

Basic features:

  • Emergency power module for three-phase inverters of the Huawei M1 series
  • Separate single-phase circuit, maximum power 3.3 kVA, IP 65, weight 11.00 kg.
  • Compatible with Huawei inverters, models M0 and M1
  • Reliable 1-phase emergency power supply
  • Automatic detection of a grid failure and switchover to battery LUNA2000
  • Maximum apparent power 3.3 kVA
