UNI-T UT673PV Solar MPPT Panel Tester — Portable 5–800W Power Meter, Large LCD, MC4 Kit

This compact, self-powered tester combines a large LCD readout with automatic and manual MPPT modes to display multiple solar-panel parameters at once. Designed for field use, the UT673PV runs directly from the solar module—no batteries required—and includes built-in protections against reverse polarity, over-voltage, over-current and overheating. It speeds troubleshooting for installers, manufacturers and maintenance teams by offering clear numeric results, data hold and a rugged carrying kit.

How does the UT673PV determine a solar panel’s true maximum power?

The meter uses an MPPT (maximum power point tracking) algorithm to sweep the panel’s operating point and find the Vmp and Imp where output power peaks. You can choose automatic MPPT for a hands-off test or manual mode to hold specific voltages or currents for comparative checks.

• Measures Pmax from 5 to 800 W, Vmp 12–60 V, Imp 0–35 A
• Automatic MPPT finds peak power quickly in fluctuating light
• Manual MPPT allows fixed-point testing and controlled diagnostics
• Data-hold freezes readings for recording or photographic documentation

What protections and safety features keep the meter reliable on-site?

UNI-T engineered multiple safeguards so the UT673PV tolerates common field errors and protects both the instrument and the operator. The unit includes reverse polarity protection plus over-voltage, over-current, over-power and over-temperature shutdowns to reduce risk during unexpected conditions.

• Reverse polarity connect protection prevents damage from wiring mistakes
• Over-voltage and over-current cutoffs limit stress on electronics
• Over-power and thermal monitoring keep readings accurate under load
• CAT 0 60V rated MC4 test lead supplied for safe connections

Which measurements are shown and how are they presented?

The display presents all key solar parameters simultaneously on a large 52 × 66 mm LCD so you can compare numbers at a glance. Readouts include maximum power (Pmax), peak voltage (Vmp), peak current (Imp), open-circuit voltage (Voc) and short-circuit current (Isc), plus simple icons to indicate test mode and protections.

• Large multi-value LCD shows Vmp, Imp, Pmax, Voc and Isc together
• Multi-language menu supports EN, FR, DE, IT, ES, SV, PL, CZ for global teams
• No internal battery—powered directly by the connected solar panel
• Includes MC4 wrench, test lead, cloth bag and manual for field use

How portable and practical is the UT673PV for daily inspections?

The meter is designed for field technicians who need a durable, lightweight tool they can carry between arrays. Its self-powered operation and included carrying accessories let you test panels without extra power sources or bulky kit, improving speed and convenience during routine maintenance or commissioning.

• Compact form factor and cloth carry bag for easy transport
• MC4-compatible test lead and wrench provided for fast hookups
• Data hold and readable display simplify documenting faults on-site
• 24/7 customer support from UNI-T for setup and troubleshooting

Who is this for: The UNI-T UT673PV suits PV installers, service technicians, manufacturing QA teams and system owners who need fast, accurate field measurements of panel performance. It is particularly useful for people who require a self-powered, protected instrument to validate maximum power point metrics, identify underperforming modules, and speed maintenance checks without carrying spare batteries or bulky test equipment.
