Solar panel multimeter for testing voltage, current, and power on photovoltaic systems. Designed to help you verify that a solar PV system is operating correctly and to compare panel performance quickly on site. Key benefits Fast verification of system performance: measures voltage, current, and power so you can confirm a panel or array is producing as expected. Compare and optimize: identify performance differences between panels or brands and find the tilt or placement for maximum output. Simple, reliable operation: no battery required plug directly to the panel and read results immediately. Built for field use: long PV connecting cables and two crocodile clip cables provide flexible connections for onroof or bench testing. Safety minded: builtin protections for overvoltage, over temperature, overcurrent, and over rated power help protect the meter and the user. Main functions and compatibility Measures solar panel voltage, current, and power for basic troubleshooting and validation. Compatible with standard photovoltaic panels and solar PV systems for onsite diagnostics and performance checks. Two PV connecting cables and two crocodile clip cables included for convenient connection options. What makes this product stand out No battery required: connects directly to the panel for immediate readings without charging or battery replacement. Multiple protective features reduce the risk of damage during measurement and support safer testing in the field. Practical cable set up supports a range of installation and testing positions without additional adapters. Performance notes Provides direct readout of key electrical parameters used to assess panel condition and output. Cable length accommodates common installation scenarios and makes it easier to reach test points. Use cases panel acceptance testing: verify voltage, current, and power on delivery to confirm panels meet expected output before installation. Roof angle and placement optimization: measure output at different tilt angles and orientations to determine the mounting position for maximum generation. Onsite troubleshooting: quickly locate underperforming panels or check array segments after shading, soiling, or suspected failure. What you get A photovoltaic panel multimeter that operates without batteries, two PV connecting cables, and two crocodile clip cables. Builtin overvoltage, over temperature, overcurrent, and over rated power protections for safer use. This tester offers a straightforward, practical way to check solar panel performance, compare panels, and troubleshoot PV systems with minimal setup.
