A professional solar testing solution combining three purpose-built FLIR instruments for photovoltaic installation, commissioning, troubleshooting and maintenance: FLIR PV78 Solar Irradiance and Temperature Meter FLIR PV48 Solar Panel Tester and I-V Curve Tracer FLIR CM78-PV 1500 V Solar Clamp Meter Together, these tools help solar professionals determine whether reduced output is being caused by environmental conditions, an underperforming panel or an electrical problem within the PV system. Available as a complete GoThermal kit or as individual instruments. Request a Kit Quotation Test more than electrical output Understand why a solar system is underperforming A voltage or current reading alone does not always tell the full story. Solar panel output is influenced by irradiance, panel temperature, orientation, inclination and the electrical condition of the panel, string and inverter circuit. The GoThermal FLIR Solar PV Testing Kit gives installers and maintenance teams the tools to evaluate these factors during one structured inspection. Measure the available solar irradiance Record panel and ambient temperature Confirm panel orientation and inclination Measure maximum panel power Generate and assess the panel’s I-V curve Check open-circuit voltage and short-circuit current Measure high-voltage DC solar strings Measure AC and DC current without disconnecting conductors Record and share field measurements Speak to a Solar Testing Specialist One coordinated solar-testing workflow Each instrument addresses a different stage of PV testing. The PV78 establishes the environmental conditions, the PV48 verifies individual panel performance, and the CM78-PV tests high-voltage strings and wider electrical systems. Used together, they provide a structured workflow from site conditions through to panel and system-level diagnostics. 1. Measure the operating conditions Use the FLIR PV78 to measure the solar irradiance and temperature present when the panel or system is being tested. Confirm the array’s direction and inclination so that electrical results can be interpreted in the correct environmental context. 2. Verify individual panel performance Use the FLIR PV48 to measure maximum power, voltage, current, open-circuit voltage and short-circuit current at panel level. Its graphical I-V curve helps identify performance characteristics that may not be apparent from a single voltage reading. 3. Test strings and electrical systems Use the FLIR CM78-PV to measure high-voltage PV circuits, string current and electrical performance across commercial and industrial solar installations. Advanced diagnostic functions support work on both the DC and AC sides of the system. The three tools in the kit FLIR PV78 Solar Irradiance and Temperature Meter with Tilt Sensor The PV78 provides the environmental measurements needed to evaluate solar panel performance under actual site conditions. It measures: Solar irradiance from 50 to 1,400 W/m² Panel and ambient temperature Array direction from 0° to 360° Panel or roof inclination from −90° to 90° The PV78 can measure temperature directly at the panel or continuously through its external temperature probe. Bluetooth connectivity allows readings to be viewed, documented and shared using the FLIR METERLiNK app. The irradiance measurements support PV installation testing requirements associated with IEC 62446-1.

Fault-finding Determine whether low output originates from poor environmental conditions, an individual panel, a string or another part of the electrical system. Panel comparison Compare the electrical performance and I-V curves of similar panels under measured site conditions. Performance verification Capture objective measurements when investigating customer complaints, warranty questions or unexpectedly low energy production. System handover Improve commissioning and handover documentation with recorded environmental and electrical measurements. Why buy the tools together? A more complete view of PV performance The three instruments answer three different but connected questions: FLIR PV78 Are the irradiance, temperature, direction and inclination suitable for the expected output? FLIR PV48 Is the individual solar panel producing and behaving as expected? FLIR CM78-PV Are the strings and wider electrical system operating correctly? Used together, they provide better diagnostic context than relying on voltage, current or irradiance measurements alone. Request a Kit Quotation FLIR METERLiNK connectivity The FLIR PV78 and CM78-PV connect wirelessly to the FLIR METERLiNK mobile app. METERLiNK helps technicians: View compatible meter readings remotely Monitor multiple measurements Track minimum, maximum and average readings View measurement trends Set high and low alarm thresholds Capture readings for documentation Create reports and share findings from the field The PV48 operates as a standalone panel tester with an integrated graphical display.

Yes. The PV78, PV48 and CM78-PV can be purchased individually or together as the GoThermal FLIR Solar PV Testing Kit. Does the kit test both individual panels and complete PV systems? Yes, but each tool performs a different role. The PV48 is intended primarily for individual panel testing up to 800 W, 60 V and 30 A. The CM78-PV is used for higher-voltage string and system-level electrical measurements up to 1,500 V DC. Why is irradiance important when testing a solar panel? A panel’s electrical output depends heavily on the amount of solar energy reaching it. Measuring irradiance and temperature provides the context needed to interpret panel power measurements properly. Does the kit produce I-V curves? Yes. The FLIR PV48 displays the current-voltage curve of the connected panel and measures its key operating points. Which instruments connect to FLIR METERLiNK? The FLIR PV78 and CM78-PV support Bluetooth connection to the FLIR METERLiNK app. The PV48 uses its own integrated display. Can the CM78-PV be used for general electrical work? Yes. In addition to solar PV measurements, it includes True RMS, VFD, LoZ, inrush current, resistance, continuity, frequency, capacitance and other functions for commercial and industrial electrical inspections. Does owning this kit automatically make an installation IEC 62446-1 compliant? No. The PV78 provides irradiance measurements used in testing associated with IEC 62446-1, but compliance depends on the complete inspection, testing, documentation and installation process.
