Bypass Diode Tester FT4310
Traditionally, bypass diodes can only be inspected for good working condition at night or when power is not being generated by the solar panels in order to verify that any applied current is guided past the solar cells. With the FT4310 Bypass Diode Tester, you can detect for open faults even when the sun is out without covering the panels. Also test for short-circuit faults and cell string losses.
Key Features
- Test for open or short-circuit bypass diodes even during the day
- Easily test using the strings in the junction boxes
- Save time
- Simultaneously measure all electrical parameters
- Automatically transfer data wirelessly (Available for Android and iOS devices)
Product Warranty Period: 3 years
