The Data Your Solar Report Actually Needs

When an inspector, asset manager, or client asks why a solar system isn’t hitting its energy yield predictions, the first question is always: what were the conditions at the time of testing? Without a calibrated irradiance measurement taken at the panel surface, any performance comparison against the manufacturer’s STC datasheet is essentially guesswork.

For solar professionals working under AS/NZS 5033 compliance obligations and the requirements of the IEC 62446-1 photovoltaic system documentation standard, having a dedicated, calibrated irradiance meter isn’t optional — it’s a core part of the commissioning and maintenance toolkit.

Four Critical Measurements. One Instrument.

The FLIR PV78 is a purpose-designed solar site measurement tool that consolidates four measurements that previously required separate instruments or cumbersome setups:

Solar Irradiance (W/m²) The PV78 measures irradiance from 0 to 1,400 W/m² — the full range you’d encounter from overcast Melbourne mornings through to peak summer radiation on a north-facing Perth rooftop. The 50–1,400 W/m² measurement range aligns with IEC 62446-1 requirements for solar PV system performance verification, making results directly usable in compliance documentation.

Panel Surface Temperature Connect the included external temperature probe and mount it directly to the panel surface for continuous module temperature readings across a range of −30 °C to 100 °C. Module temperature is essential for accurate STC correction — a panel at 65 °C will deliver measurably less power than at 25 °C, and documenting that temperature gives your performance calculations credibility.

Ambient Temperature The built-in meter sensor captures ambient temperature from −10 °C to 50 °C, logged alongside irradiance for contextual reporting — particularly useful when comparing against manufacturer performance guarantees or modelling seasonal yield variation.

Tilt Angle and Compass Direction The integrated tilt sensor and compass let you verify and document the physical orientation of panels and arrays. For new installations, this confirms panels have been mounted at the specified pitch and azimuth. For performance investigations, it helps rule out suboptimal positioning as a contributing factor to underperformance. A quick check during commissioning can prevent the kind of dispute that arises months later when an owner questions why their north-facing system is underperforming.

METERLiNK — From Rooftop to Report Without the Clipboard

One of the most practical features for busy solar teams is the FLIR METERLiNK® Bluetooth connectivity. Rather than squinting at a screen, manually transcribing values, and entering data back at the office, the PV78 transmits live readings wirelessly to the METERLiNK mobile app on your Android or iOS device.

From the app, you can monitor multiple compatible FLIR meters simultaneously, log readings with timestamps, annotate with site notes, and generate reports directly from the field. Share results with a client or upload to a job management system before you’ve even packed your test kit. For compliance-focused work, the digital audit trail is an added benefit over handwritten site notes.

The METERLiNK app also integrates with compatible FLIR thermal cameras, allowing irradiance and temperature data to be embedded directly into thermal inspection images — a significant workflow improvement for thermographers conducting PV array inspections.

Built for Australian Solar Conditions

The PV78 was designed to be positioned on or near the panel surface for continuous monitoring, not just a quick spot reading. The external probe and mounting bracket enable it to be secured in place during extended testing sessions — useful for monitoring irradiance variation during partial cloud cover, or for logging conditions over a test period to build a more representative performance picture.

The high-contrast, large LCD remains visible in direct sunlight — critical for working on rooftops in Australian summer conditions where display washout is a real usability problem with cheaper instruments.

Who Uses the FLIR PV78?

CEC-accredited solar installers use the PV78 during commissioning to capture the irradiance and temperature conditions at the time of performance testing — providing the contextual data required for IEC 62446-1 documentation and demonstrating diligence under AS/NZS 5033 requirements.

Solar O&M teams use it during scheduled maintenance visits and performance investigations, logging irradiance alongside system output data to calculate performance ratio and identify degradation or shading losses.

Solar surveyors and designers use it during pre-installation site surveys to document available solar resource and verify optimal panel orientation before system design is finalised.

Large-scale solar farm operators use the PV78 alongside dataloggers and monitoring systems to cross-reference on-ground irradiance against pyranometer data for yield analysis and performance modelling validation.

Is Your Solar Array Actually Delivering What It Should?

You’ve just commissioned a new rooftop installation, or you’re six months into a service contract and a customer is reporting lower-than-expected yield.

Without the right test gear, you’re guessing. Shading losses, panel mismatch, cell degradation, or a faulty bypass diode can silently rob kilowatt-hours — and tracking down the culprit with a basic multimeter takes time you don’t have on a busy site.

For Australian solar installers and maintenance teams working across residential rooftops, commercial arrays, and utility-scale projects, having a purpose-built panel tester isn’t a luxury — it’s the difference between a quick sign-off and a costly callback.

One Tool. Every Key Panel Parameter.

The FLIR PV48 is built specifically for on-panel performance testing. Rather than cycling through a multimeter’s measurement modes and manually calculating Pmax, this dedicated I-V curve tracer captures the complete current-voltage characteristic of a solar panel in a single test sweep.

The result is a real-time graphical I-V curve plotted on the large, high-contrast LCD — immediately showing whether the panel is producing power along its expected characteristic curve or whether something is pulling performance off-spec.

In a single test, the PV48 simultaneously captures:

• Pmax — maximum power output in watts
• Voc — open-circuit voltage
• Isc — short-circuit current
• Vmax — voltage at maximum power point
• Imax — current at maximum power point
• Ambient temperature — for contextual STC correction

The graphical I-V curve overlay is the key differentiator here. Rather than just reading a number, you can visually identify whether the curve shape indicates shading, bypass diode issues, internal resistance problems, or general degradation — all without needing to pull the panel off the roof.

Built for the Australian Worksite

The PV48 handles panels up to 800W — which covers the broad majority of residential and commercial modules in Australian installations today, including common 400–700W mono-PERC and TOPCon panels.

The large, high-contrast LCD remains readable even under direct Queensland or WA sun — a practical necessity that many importers overlook. The instrument is powered by a built-in lithium-ion battery, so there are no AA batteries to track down mid-job.

The included CAT III-300V MC4 PV plugs and CAT III-300V double-moulded alligator clips mean you can connect directly to panel terminals without sourcing aftermarket adapters. The compact 206g body — roughly the size of a large smartphone — tucks easily into a tool bag and doesn’t add fatigue on multi-array inspection days.

Certified to IEC 61010-1 safety standards with CE and RCM marks, the PV48 meets the compliance expectations you’d expect from a professional-grade instrument.

Who Uses the FLIR PV48?

Solar installers and CEC-accredited designers use the PV48 during pre-energisation commissioning to confirm each panel meets its rated output before sign-off under AS/NZS 5033. A quick sweep of each string confirms the panels are healthy before the inverter goes live.

Solar maintenance contractors carry the PV48 as their first diagnostic tool when a customer reports reduced generation. An I-V curve sweep quickly distinguishes between a panel fault, a string wiring issue, or an inverter-side problem — reducing callout time significantly.

O&M teams on commercial and industrial solar arrays use the PV48 in scheduled maintenance rounds to track panel performance over time, identifying early-stage degradation or bypass diode failures before they cause larger system losses.

Solar panel importers and quality assurance teams use it in goods-in inspection to verify panel performance against manufacturer datasheets, catching underperforming batches before they’re installed.

Testing Modes

The PV48 offers multiple testing modes to suit different workflows:

• I-V / PV Curve mode — captures and displays the full I-V and P-V characteristic curve with Pmax, Vmax, and Imax
• Batch mode — runs a quick 10-reading test session for rapid screening of multiple panels
• Peak Data mode — takes 30 readings across three data pages for thorough per-panel analysis
• Manual mode — high-accuracy measurements for low-power panels (≤100W), ideal for small or damaged modules requiring careful assessment

Technical Specifications

Conversational query: “What does an I-V curve tracer tell you about a solar panel?”

An I-V curve tracer maps the current-voltage relationship of a solar panel across its full operating range in a single sweep.

The shape of the resulting curve reveals how well the panel is performing — a healthy panel produces a characteristic S-shaped curve reaching its maximum power point cleanly. Flat spots, kinks, or a reduced fill factor can indicate shading, bypass diode failure, internal cell damage, or series resistance problems.

The FLIR PV48 displays this curve graphically on screen, making it possible to visually diagnose panel faults on-site without sending data to a laptop.

Conversational query: “How do I check if a solar panel is performing to specification?”

To verify a solar panel against its datasheet spec, you need to measure open-circuit voltage (Voc), short-circuit current (Isc), and maximum power (Pmax) under known irradiance and temperature conditions.

A dedicated I-V curve tracer like the FLIR PV48 captures all three parameters — plus the full current-voltage curve — in one test. Pair it with the FLIR PV78 irradiance meter to record simultaneous irradiance and module temperature, giving you everything needed to calculate STC-corrected performance and confirm compliance with the panel’s rated specifications.

Anyone who’s commissioned solar installations knows the drill: juggling multiple meters, manually shorting DC terminals for insulation tests, climbing on and off roofs repeatedly to verify string performance, then spending hours compiling test results for compliance documentation. When you’re racing daylight to complete AS/NZS 5033 commissioning on a 50kW commercial array, every minute counts.

The HT Instruments HT PVCHECKS-ONE multifunction commissioning tester cuts through this complexity with a single-instrument solution designed specifically for modern PV installations. Whether you’re commissioning residential arrays under the Clean Energy Council guidelines or managing large-scale solar farms, this Italian-engineered diagnostic platform delivers comprehensive electrical safety verification and performance testing without the equipment juggling act.

One Button, Complete Commissioning Test Sequence

The standout feature that separates PVCHECKS-ONE from conventional testing approaches is the automated “GO” function. Connect to your array’s DC terminals, press one button, and the instrument executes the complete electrical safety test sequence required by IEC/EN 62446 and AS/NZS 5033:2021. Within minutes, you’ll have verified continuity of protective conductors, confirmed polarity, measured open-circuit voltage, tested short-circuit current, and performed insulation resistance testing—all documented with pass/fail indicators.

For solar installers working through combiner boxes on commercial installations, the AUTOSTART mode enables sequential testing of all strings without manual intervention between measurements. Connect once, initiate testing, and the PVCHECKS-ONE automatically advances through each string in the combiner, documenting results as it progresses. This workflow efficiency translates directly to reduced labour costs and faster project completion.

Revolutionary DUAL Function Eliminates External Shorting Hardware

Here’s where PVCHECKS-ONE represents genuine innovation in PV testing methodology. Traditional insulation resistance testing on photovoltaic arrays requires physically shorting positive and negative DC terminals with an external switch before connecting your insulation tester. This means additional hardware to carry, extra connection steps, and increased opportunities for measurement error or safety incidents.

The PVCHECKS-ONE’s patented DUAL function performs insulation resistance measurements at 250V, 500V, or 1000V DC test voltages without requiring external shorting equipment. Whether you’re testing a single module, an entire string, or a complete PV array, the instrument handles terminal shorting electronically while simultaneously measuring insulation to ground from both positive and negative conductors. You receive three critical measurements—total parallel resistance, positive pole resistance to ground, and negative pole resistance to ground—identifying exactly where insulation degradation exists.

This capability proves particularly valuable when troubleshooting installations with suspected ground faults. The included GFL (Ground Fault Locator) function identifies precisely between which modules in a string an insulation problem exists, eliminating the guesswork from fault diagnosis and dramatically reducing repair time.

Real-World Performance Testing Under Operating Conditions

AS/NZS 5033:2021 requires verification that installed modules perform according to manufacturer specifications. The PVCHECKS-ONE measures open-circuit voltage (Voc) up to 1000V and short-circuit current (Isc) up to 30A under actual operating conditions, then mathematically refers these measurements to Standard Test Conditions (STC) when paired with the optional SOLAR03 environmental monitoring unit.

The SOLAR03 remote unit (sold separately) wirelessly connects via Bluetooth BLE and simultaneously measures front-side irradiance using the HT305 reference cell, module temperature via PT305 probe, and array inclination angle. Real-time environmental data feeds into PVCHECKS-ONE’s performance algorithms, delivering accurate STC-corrected results that can be compared against manufacturer datasheets for compliance verification.

For installers working with bifacial modules—increasingly common in commercial and utility-scale installations—the optional KIT BIFACIALONE (2× HT305 cells + SOLAR03) enables simultaneous measurement of front and rear irradiance, accounting for ground reflection and backside gain in performance calculations.

OPT Function: Testing Arrays with Module-Level Power Electronics

Modern PV installations increasingly incorporate module-level power electronics (MLPE) such as DC optimizers, rapid shutdown devices, and microinverters. These devices present challenges for traditional insulation testing because their internal circuitry can interfere with test voltages, often requiring disconnection before testing—a time-consuming process on large installations.

The PVCHECKS-ONE’s OPT function specifically addresses this installation reality. When testing strings equipped with SolarEdge optimizers, Tigo devices, or similar MLPE equipment, the OPT mode applies modified test protocols that obtain valid insulation measurements without requiring disconnection of optimizers from modules. This feature alone saves hours on commercial installations with hundreds of optimized modules.

Built for Australian Solar Installation Environments

Australian solar installers face unique environmental challenges—extreme UV exposure, temperature swings from sub-zero mornings to 45°C+ afternoons, coastal salt air corrosion, and red dust that infiltrates everything. The PVCHECKS-ONE’s CAT III 1000V AC, CAT III 1500V DC measurement category rating and robust Italian construction handles these conditions while maintaining measurement accuracy.

The instrument ships with MC4-compatible connection adapters (KITPCMC4), four-colour alligator clip test leads (KITGSC4), protective hard case (VA507), and factory ISO calibration certificate. For installers coordinating with Clean Energy Council requirements or state-based commissioning documentation, the optical/USB interface enables direct connection to Windows-based reporting software for automated compliance document generation.

Fluke TruTest™ Solar Database App

Make testing easier and more efficient with the Fluke TruTest™ Solar Database App, designed for seamless collaboration with the SMFT-1000 Multifunction PV Tester. The app features an extensive solar panel database that allows for importing panel specifications directly into the analyzer, allowing access to over 120,000 different types of PV panels wherever you are and eliminating the need for manual input to significantly streamline the testing process.

Wireless Irradiance Meter: No leads required

To perform precise I-V curve measurements, real time irradiance and temperature data is needed. The included IRR2-BT irradiance meter wirelessly connects to the SMFT-1000 to communicate data in real time, providing the most accurate I-V curve measurements possible.

If the wireless connection is interrupted for any reason, the IRR2-BT will continue recording data for up to 17 hours that can later be matched to tests taken with the SMFT-1000.

It’s a hassle to change the configuration of test leads constantly while doing different tests. With Fluke’s “Keep the Leads” system, less time is wasted on set-up, and less user errors occur while testing PV systems. Now you can get more testing done in the field in less time

Color Screen with Integrated Interface: On-screen instructions provide an easy walkthrough of tests

Switch the SMFT-1000 to Auto Test Mode to perform an automatic sequence of tests in a variety of combinations:

• With insulation test or without insulation test
• IEC 62446-1 testing for Category 1 or Category 1 and 2
• IEC 62446-1 testing for Protection Class I or Protection Class II

On-location I-V curve results: compare manufacturer I-V curve data to measured data instantly

While taking an I-V curve reading in the field, the SMFT-1000 will display the curve as it loads in the test data, against the module specifications as defined by the manufacturer.

This makes it easy to immediately confirm measurements without the use of a laptop or tablet. Run the I-V curve test on new installations to confirm they are working according to the site specifications, or to test if existing modules or strings are working to their expected performance levels. Accurately measures modules with an efficiency of up to approximately 19%.

Record visual inspections, then manage data with TruTest™ Solar Software

To meet PV system IEC regulations for visual inspections, the SMFT-1000 features a convenient setting in which to record observations directly to the memory. Later, the information can be downloaded to the TruTest™ software and incorporated into the project report.

TruTest™ allows for solar asset management, data storage and reporting on a single platform. Whether you are analyzing panel efficiency through I-V curves, or safety testing the system through the Category 1 test regime in conformance to IEC 62446-1, proper data management is critical for producing easy-to-understand reports for clients.

TruTest™ Software allows you to quickly and easily import measurement results directly from your solar multifunction tester to computer, organize and analyze the data, compare individual asset data against previous measurements imported and provide a comprehensive and visual client report.
