Hioki FT4310 Bypass Diode Tester

Hioki FT4310 Bypass Diode Tester
Inspect solar panel bypass diodes for opens and shorts in broad daylight without covering panels

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*1
• Easily test using the strings in the junction boxes*2
• Save time - simultaneously measure all electrical parameters*3
• Automatically transfer data wirelessly (Available for Android and iOS devices*4)

*1 Testing can also be performed at night. Testing for short-circuit faults can only be performed during the day.
*2 There is no need to climb onto the roof and dramatically improving work efficiency.
*3 Measure open-circuit voltage, short-circuit current, and bypass route resistance and display all three values at once.
*4 Automatically transfer data with Bluetooth® wireless technology
