## Summary description

The Unit UT673PV is an MPPT tester designed for testing and evaluating solar MPPT charge controllers and PV panels. Supporting power range 5–800 W and current 0–35 A, it measures output behavior under load, verifies MPPT tracking, and helps diagnose performance issues. Useful for installers, technicians, and hobbyists for commissioning, maintenance and troubleshooting of solar systems.

## Long description

The Unit UT673PV MPPT Tester is a diagnostic instrument for evaluating the performance of solar MPPT charge controllers and PV panels. It is designed to apply controlled loads and measure output behavior across a power range of 5–800 W and a current range of 0–35 A, enabling observation of MPPT tracking, voltage and current response, and stability under realistic operating conditions. The tester helps verify whether a charger follows maximum power point algorithms correctly and assists in identifying mismatches, wiring issues or performance degradation in solar systems.
Advantages
The tester offers precise load application and real-time measurement of voltage and current to replicate typical PV operating conditions. Compact and purpose-built for MPPT evaluation, it supports a wide power span from small to mid-size installations and provides repeatable test conditions for commissioning and troubleshooting. The instrument is suitable for field use and lab checks where controlled, measurable loads are required to validate controller behavior without depending on variable sunlight.
Suitable for
Commissioning and functional checks of solar MPPT charge controllers
Verification of PV panel output and MPPT tracking performance
Maintenance and fault diagnosis of off-grid and hybrid solar systems
Training, test benches and product evaluation in workshops
Key specifications
Supported power range: 5–800 W
Output current range: 0–35 A
Designed for testing MPPT charge controllers and PV panels
Measures output voltage and current behavior under load
Enables observation of MPPT tracking and stability
How to use
Connect the tester between the PV panel (or simulator) and the MPPT charge controller following the controller and tester connection diagrams. Set the desired load or power parameters within the supported ranges and start the test sequence to monitor voltage, current and power behavior. Observe how the controller adjusts its operating point and record any deviations from expected MPPT tracking. Use incremental changes in load or irradiance simulation to assess dynamic response and repeat tests to confirm reproducibility.
Usage recommendations
Use the tester in well-ventilated areas and ensure connections are secure before applying loads. Keep tests within the specified power and current limits, and allow equipment to cool between extended runs. For safety and accurate results, follow the MPPT charger manufacturer’s wiring and operating instructions and perform tests under controlled conditions to avoid transient damage or false readings.
