Top 5 Features to Look for in a Solar PV Isolator Switch

When investing in solar components, the isolator switch should never be overlooked. A quality DC isolator switch ensures the safety of your PV system, especially during maintenance or emergencies. Here are five must-have features:

1. High Voltage and Current Rating

Ensure your isolator can safely interrupt the maximum voltage and current produced by your solar array.

2. Arc Suppression Technology

DC circuits are more prone to arc formation. A quality isolator should incorporate mechanisms for safe arc suppression.

3. IP66 Weatherproof Enclosure

If installed outdoors, your switch must resist water, dust, and UV damage. An IP66-rated enclosure is the standard for reliability.

4. Lockable Handle

This feature prevents accidental reconnection during maintenance and complies with workplace safety standards.

5. IEC 60947-3 Compliance

Ensure the isolator switch meets global standards to guarantee long-term reliability and legal compliance.

By focusing on these key features, you can enhance the safety and efficiency of your solar installation.
