Dual Power Automatic Transfer Switch – ATS for PV Solar & Backup Systems
This dual power automatic transfer switch (ATS) is designed to ensure uninterrupted power supply for critical DC loads in photovoltaic systems. It continuously monitors the primary power source (solar PV / battery) and automatically transfers the load to a backup source (grid / secondary battery) when the primary source fails or drops below preset thresholds. Ideal for off-grid solar systems, hybrid PV installations, and critical DC backup applications where power continuity is essential. With a compact DIN rail design and fast switching response, this ATS delivers reliable, maintenance-free performance for years of operation.
