Safely Disconnect Solar PV Strings for Maintenance & Protection | IMO DC Disconnect Rooftop Isolator Switch
The IMO DC Disconnect Rooftop Isolator Switch is a True DC isolator designed to safely disconnect photovoltaic panels from DC/AC inverters in solar power systems. Engineered specifically for solar applications, this rooftop isolator provides reliable DC switching, enhanced safety protection, and code-compliant system isolation for residential and commercial solar installations.
Key Benefits
- True DC Isolation – Designed specifically for DC solar applications, not a modified AC switch.
- Safe PV System Disconnect – Safely isolates photovoltaic strings from the inverter during maintenance or emergency shutdown situations.
- Supports Multiple Solar Strings – Configured for 4-string solar installations with 8 poles in series.
- Lockable Off Position – Safe-lock functionality helps prevent accidental system reconnection during servicing.
- High-Speed Switching Mechanism – Operator-independent switching with arc cooling chambers improves safety and reliability.
- Weather-Resistant Enclosure – IP67 and NEMA 4X rated enclosure supports demanding rooftop and outdoor installations.
- Compact Installation Design – Space-saving enclosure with easy wiring access simplifies installation.
Use Cases
Ideal for residential and commercial rooftop solar installations requiring NEC and IEC-compliant DC isolation between photovoltaic panels and inverters.
