This AC/DC auto‑switching controller in the 15–22 kW range is built for demanding applications—such as large‑scale solar‑pumped irrigation, commercial bore‑well water supply, or any heavy three‑phase motor load with both solar and grid/backup power available. It accepts high‑voltage DC from the solar array (via MPPT technology) and AC mains (or generator) input, and intelligently selects the most optimal source—prioritising solar when available, switching to AC when solar input drops below a threshold.
