Components
Pixii Home Off-grid Box
Enables off-grid operation with PV and genset
Prepare Pixii Home for off-grid operation
The primary function of the off-grid box is to automatically disconnect from the grid and initiate off-grid operation for critical loads. The transition typically occurs in less than 5 seconds.
Once the grid is stable again, critical loads are reconnected to the grid, and Pixii Home resumes normal operation in grid-tied mode.
The off-grid box is designed for safe disconnection and isolation of Battery Energy Storage Systems (BESS) from the grid, in off-grid and hybrid systems.
Compatible with both the AC and hybrid versions of Pixii Home.

Functions
Backup power
Maintain power supply to critical loads from the battery during grid outages.
PV self-consumption during outages
Utilize both AC- and DC-coupled PV systems during grid outages, with AC frequency regulation to stabilize local power supply.
Power congestion relief
Increase peak power availability beyond transformer, line, or fuse limitations to handle local consumption peaks.
Microgrid operation
Supply power in a locally isolated grid using PV and/or generators, optimizing solar utilization and reducing fuel consumption per kWh.
Phase balancing*
Control active and reactive power per phase to distribute loads more evenly and support power quality.
* Phase balancing is available only when integrated via an external EMS (Energy Management System). Load balancing is achieved by controlling P and Q per phase.
