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.

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 (1260 V, 035 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>
Applications
Solar PV installation commissioning; panel and string performance checks; preventive-maintenance and O&M surveys; and incoming or quality inspection of photovoltaic modules.
Frequently Asked Questions
Does the UT673PV need batteries?
No it is powered directly by the solar panel being tested.
What does it measure?
Maximum power (5800 W), open-circuit and peak-power voltage (1260 V), and short-circuit and peak-power current (035 A), plus a manual MPPT test.
How does it connect to panels?
Through integrated MC4 connectors, so it plugs into standard solar leads without adapters.
