In off-grid operating mode, the hybrid system prioritizes energy independence. Here, solar PV and the battery bank become the primary sources of power, supplying the load throughout the day and night. The national grid is treated only as a secondary backup resource, used when both solar production and battery levels are insufficient.

During the day, solar energy directly powers the load and charges the batteries. At night or in low-sunlight conditions, the stored battery energy takes over. If battery levels run too low, the system can automatically switch to the national grid, or to an optional generator, solely for backup support. This mode is ideal for customers who want maximum reliance on renewable energy and minimal dependence on the grid.
