Overview

The UT673PV is a purpose-built solar diagnostic that finds a panel's maximum power point and reads the numbers that tell you whether it's performing: maximum power from 5 W to 800 W, open-circuit voltage and peak-power voltage from 12 V to 60 V, and short-circuit and peak-power current from 0 A to 35 A. It connects through integrated MC4 connectors and is powered by the panel under test — no batteries to charge.

A manual MPPT test, a data-hold function, and a large color LCD make field readings quick, and built-in protections (reverse polarity, overvoltage, overcurrent, overtemperature, overpower) guard the meter in real installations. The compact 143 × 74 × 25 mm body fits a pocket. It's backed by UNI-T's nearly 40 years of test-meter manufacturing.

UT673PV Details

Maximum Power Point on the Spot

The UT673PV runs a manual MPPT test to find where a panel delivers its most power, reading maximum power from 5 W to 800 W. That single figure tells you quickly whether a panel or string is performing or losing output to shading, soiling, or degradation.

The Full PV Picture

Beyond peak power, the meter reads open-circuit voltage and short-circuit current (12–60 V, 0–35 A) — the values that diagnose a panel against its nameplate and pinpoint why output is low.

Battery-Free, MC4-Ready

Powered directly by the panel under test, the UT673PV never needs charging, and integrated MC4 connectors plug straight into standard solar leads without adapters — practical for moving down a string in the field.

Protected & Pocketable

Reverse-polarity, overvoltage, overcurrent, overtemperature, and overpower protection guard the meter in real installations, and a 143 × 74 × 25 mm body with a data-hold function keeps it quick and portable.

Applications

Solar PV installation commissioning; panel and string performance checks; preventive-maintenance and O&M surveys; and incoming or quality inspection of photovoltaic modules.
