Solar + Battery + Grid (3-in-1)
Solar + Battery + Grid — maximum flexibility, all-day coverage.

The smartest mode. When solar generation exceeds AC consumption, it runs 100% on solar and charges the battery. When solar is insufficient, the battery kicks in. When both solar and battery are depleted, it automatically switches to grid power. Ensures 24-hour uninterrupted cooling with zero manual intervention.
