Portable solar panel tester for residential and commercial use Key benefits Wide compatibility: Supports 12 volt to 60 volt PV modules, making it suitable for most photovoltaic panels used in home and commercial installations. power handling: Up to 800 watt maximum power capacity enables testing of small to medium solar panels and strings for a range of energy projects. Precise diagnostics: Builtin LCD displays pmax, vmp, imp, voc, and isc, and provides realtime voltage, current, and power readings for accurate assessment. Flexible operation: Auto and manual testing modes allow automatic sweeps to find operating points or manual adjustments to test specific conditions, helping identify the maximum power point and optimize energy conversion. Practical for field and workshop use: Designed to support both routine commissioning and troubleshooting tasks across different installation scales. What it does Measures opencircuit voltage and shortcircuit current along with operating voltage, current, and calculated maximum power to give a full picture of panel performance. Runs automatic MPPTstyle sweeps when needed or lets technicians select manual settings for controlled tests and verification. Handles a variety of panel types and configurations within the 12 V to 60 V and up to 800 W range. Applications Rooftop commissioning: Verify individual modules and small strings during installation to confirm expected output and spot faulty or underperforming panels. Commercial array maintenance: Test panels or substrings during periodic maintenance to identify declines in module performance and prioritize repairs. Offgrid and smallscale project setup: Confirm component selection and system behavior when assembling offgrid systems, small solar generators, or educational lab setups. Performance and compatibility Voltage range: 12 V to 60 V supports common PV module voltages used in residential and commercial systems. Power capacity: 800 W maximum to accommodate a wide set of panel ratings and test scenarios. Readout: LCD clearly shows pmax, vmp, imp, voc, and isc for immediate interpretation of results. Modes: Auto and manual testing modes provide both handsoff scanning and precision control. Why choose this tester Enables faster, more informed decisions during installation and maintenance by delivering reliable, realtime measurements. Reduces guesswork when identifying underperforming modules or confirming expected output under specific conditions. Suitable for technicians, installers, and system integrators who need a single tool to evaluate panels across multiple project types and settings.
