Solar Power Measuring Instruments for Maintenance and Inspection Applications Verify the Correct Power Level to Solve Power Loss Problems Estimate power In. i- and other information are available on our website. Expected power is estimated based on irradiation and panel temperature. Patent pending. Identify problem Estimate expected production Investigate power and current for individual strings and identify the string with the issue. Using the instrument with a masking shield or similar device, identify the failed module. Problem solved.

Features • Estimate expected electricity production (estimated electrical energy). • Estimate the expected electricity production at the current time under continuously varying conditions of air temperature and insolation. • Compare the estimate with actual electricity production. • Production can be measured without shutting off the circuit. • Investigate module failures by identifying strings with wiring breaks and using the instrument in conjunction with a masking shield. • Add up to 7 more channels of clamp or temperature measurements even in PV mode. • When PV mode is turned OFF, the instrument...

Hioki Meets A Variety of PV Applications Identify power conditioner malfunctions By combining the Hioki Power Analyzer Model 3390 with AC/DC current sensors, you can simultaneously measure power conditioner input and output characteristics. Connecting the instrument is simple with plug-in clamp sensors. Higher-accuracy measurement is also possible by using pass-through sensors. In a grid-tied system, this single instrument can also measure the amount of energy bought and sold over the power lines to which the power conditioner is connected. Power conditioner Commercial power circuit Load Solar...

Extensive Product Line Field Measuring Instruments Complete insulation resistance testing with one single instrument Insulation Tester IR4056-20, IR4057-20 with Bar Graph Use the built-in comparator (comparison judgment) function to compare reference and measured values and generate PASS/FAIL judgments. Identify PASS/FAIL using light and sound. Check charging status behavior with a bar graph. Choose a single-, or 3-range model depending on your application FAIL (Red) When the measured value is less than the reference value Luminous Scale Continuous beep 3-electrode measurement provides greater...
