This integrated design reduces equipment footprint, simplifies wiring, and streamlines the testing workflow on your solar panel production line. ###### Full Automation Capability with PLC Interface Equipped with both RS232 communication and I/O (PLC control) interfaces, this tester is purpose-built for integration into fully automated solar module production lines. Connect it directly to your PLC system to achieve seamless, hands-free safety testing at production speed without manual intervention. ###### Configurable Pass/Fail Judgment with Audible and Visual Alarms Operators can set upper and lower limit thresholds for each test parameter. When a test result falls outside the acceptable range, the instrument triggers both audible and visual alarms, effectively eliminating the risk of defective products passing through undetected and ensuring 100% quality screening. ###### Four-Wire Measurement for Maximum Accuracy The ground continuity test employs a four-wire (Kelvin) measurement technique, which completely eliminates the influence of test lead resistance from the measurement. This ensures highly precise and repeatable resistance readings, which is critical for verifying the safety integrity of solar module grounding connections. ###### User-Friendly Full Keyboard Operation The intuitive full-keyboard interface makes parameter setting and test operation straightforward and efficient. Operators can quickly configure test sequences, voltage levels, current limits, and timing parameters, reducing setup time and minimizing the potential for operator errors. ###### Fast Overcurrent Cut-Off Protection The instrument features rapid overcurrent cut-off circuitry that immediately terminates the test output when an abnormal current is detected. This protects both the device under test (DUT) and the operator, ensuring safe operation even when testing defective modules. ###### IEC 61215 and IEC 61730 Compliance The CHT9980A/CHT9981A fully meets the testing requirements specified in IEC 61215 (Design Qualification and Type Approval for Crystalline Silicon Terrestrial Photovoltaic Modules) and IEC 61730 (Photovoltaic Module Safety Qualification), making it an ideal instrument for both production-line quality control and type-approval testing. ##### Applications The CHT9980A/CHT9981A PV Safety Comprehensive Tester is widely used across the photovoltaic manufacturing industry and beyond: ###### Solar Photovoltaic Module Production As an essential end-of-line testing instrument, the CHT9980A/CHT9981A performs mandatory safety compliance testing on finished solar panels, including PERC, TOPCon, IBC, ABC, HPBC, shingled, and MBB modules in G1, M6, M10, and M12 cell formats. It is a critical component in any complete solar panel production line from Ooitech. ###### DC Withstand Voltage (Hipot) Testing The hipot test applies a high DC voltage between the solar module's active circuitry and its frame or backsheet to verify that the electrical insulation can withstand voltage stresses far exceeding normal operating conditions. The standard test voltage is typically calculated as 2 x rated working voltage + 1,000 V. ###### Insulation Resistance Testing This test measures the resistance between the module's live conductors and its enclosure or frame by applying a constant DC voltage (typically 500 V or 1,000 V) for a specified duration. A sufficiently high insulation resistance value confirms that the module's dielectric barriers are intact and will prevent leakage current during operation. ###### Ground Continuity Testing The ground continuity test verifies the quality of the electrical connection between the module's grounding point and its metallic frame by passing a high current (up to 60 A or 80 A) through the grounding path. Low contact resistance confirms that, in the event of an insulation failure, fault current will be safely conducted to ground. ###### Wet Leakage Current Testing The instrument supports wet leakage current testing procedures, which simulate real-world exposure to moisture and verify that the module maintains adequate insulation performance under wet conditions, a critical requirement under IEC 61215. ###### General Electrical Safety Testing Beyond photovoltaics, the CHT9980A/CHT9981A is suitable for safety compliance testing of household appliances, electronic instruments, electronic equipment, electronic components, wires, cables, and other electrical products requiring hipot, insulation, and ground resistance verification. ##### Contact Ooitech to Order the CHT9980A/CHT9981A PV Safety Comprehensive Tester Ooitech is a leading provider of complete solar panel production line equipment, from 5 MW to 1 GW capacity, covering everything from cell laser cutting, tabber stringers, layup machines, laminators, framing machines, EL testers, IV testers (sun simulators), and safety compliance instruments like the CHT9980A/CHT9981A.
