Compact solar panel tester that delivers the key measurements you need on site with speed and accuracy. Simultaneously measures maximum power output Pmax, open circuit voltage Voc, and short circuit current Isc for panels up to 800W and 60V, helping you verify performance and diagnose issues without guesswork. Key benefits Fast, accurate readings: Get simultaneous Pmax, Voc, and Isc measurements to confirm panel output and detect underperformance quickly. Clear outdoor visibility: Large digital LCD remains readable in direct sunlight so you can work reliably on rooftops or in the field. Protects equipment during testing: Builtin over voltage, over temperature, over current, and over rated power protection helps prevent damage to both the tester and the solar equipment. Lightweight and portable: Compact footprint with included cable kit makes it easy to carry between sites and store with your toolset. Features and specifications Measurements: Pmax, Voc, Isc measured simultaneously for efficient testing. Measurement limits: Suitable for solar panels under 800W and up to 60V. Display: Large digital LCD designed for clear visibility in direct sunlight. Safety: Over voltage protection, over temperature protection, over current protection, and over rated power protection. Size: Measures 5.59 x 2.99 x 0.79 inches; comes with a cable kit for immediate field use. Why customers choose this tester Saves diagnostic time by providing the most important panel metrics at once. Reduces the risk of misdiagnosis with direct measurements rather than calculated estimates. Designed for outdoor use with a visibility display and rugged protection systems. Small footprint and included cables reduce the gear you need to carry for routine checks. Typical use scenarios Rooftop inspection and commissioning: Verify panel strings deliver expected maximum power and confirm Voc and Isc before system activation. Field troubleshooting and maintenance: Quickly identify underperforming panels or string issues during site visits without returning to the . Mobile power and recreational systems: Test portable or RV solar panels on site to ensure panels are producing safely within rated limits. Who this is for Solar technicians, installers, and maintenance personnel who need reliable onsite measurements. Homeowners and hobbyists who want to verify the output of small to medium solar panels. Anyone working with solar panels under 800W and 60V who needs a compact, protective, and easytoread testing tool.
