Are You Sure All Positive and Negative Poles of Your PV Panels Are Connected Correctly?
Incorrect polarity can lead to serious issues:
equipment damage, power loss, and even safety hazards like electrocution or fire.
That’s exactly why polarity testing matters — and it’s just one of the essential tests AQ Electric performs to ensure your solar system is safe, efficient, and built to last.
Why Polarity Testing Matters:
– Confirms correct DC wiring connections
– Prevents reverse polarity that can damage inverters or modules
– Reduces risk of short circuits, overheating, or fire
– Helps identify wiring or installation errors before energizing the system
– Required as part of IEC 62446-1 standard for system verification

Don’t skip this test and depend on good luck — incorrect polarity can lead to costly damage, performance loss, or even dangerous hazards.
