Hioki FT4310 Bypass Diode Tester

Description

The Hioki FT4310 is a bypass diode tester designed for the maintenance and inspection of solar photovoltaic (PV) systems. It allows for the detection of open and short-circuit faults in bypass diodes during daylight hours without needing to cover the solar panels, a task that was previously difficult or required testing at night.

Key Features

• Daylight testing: It can detect open faults even when panels are generating power, eliminating the need to cover panels and improving work efficiency.
• Comprehensive measurements: In addition to open and short-circuit faults, it can detect cell string losses and the degradation of bypass diodes, which can manifest as increased resistance.
• Simultaneous parameter display: A single measurement displays all three electrical parameters needed for fault identification: open-circuit voltage, short-circuit current, and bypass route resistance.
• Bluetooth wireless technology: The device can automatically transfer measurement data to smartphones and tablets via Bluetooth, using Hioki's dedicated app, GENNECT Cross.
• Easy-to-use comparator function: A built-in comparator function provides pass/fail judgments based on preset values, making it easier to discover anomalies.
• Enhanced safety: The tester allows for measurements from junction boxes, avoiding the need to climb onto roofs. It is also built to be drop-proof (1 meter).
• User-friendly accessories: Features include test leads with a built-in "hold" button and a backlight for working in poorly lit locations.
