elejoy 800W Solar Panel Tester MPPT Photovoltaic Multimeter & Watt Meter Smart Portable Tool for Solar PV Panel Data & Troubleshoot Measures Power Output, Performance and Open Circuit Voltage

Like the ease of connection with the MC 4 connection enabled me to find a bad panel that I couldn’t find any other way. Overall I used it one panel at a time which is what is intended and it works absolutely perfectly. Now I have peace of mind that I can keep an eye on my panels degradation over time and angle placement power generation. It is a one trick pony but performs the trick I needed perfectly every time.

It can do one panel which is nice but I needed it to do a more but not enough room in it other words if you got a run you still have to do each panel to see if that's where it's at on that run where you can't just test the Run and now that I'm going to go with endphase it's useless

This is a handy solar-specific multi-meter for geeks like me. It measures a variety of solar panel parameters with a push of a button. It can handle up to 800 watts at voltages from 12-60 volts. It comes with connecting cables that attach to the unit like most multi-meters. I like to test solar panels but have always used a partially discharged solar generator as the plug-in source. Now I can use this simple to use solar multi-meter. Genius!
