I will walk you through my favorite clamp meter for all DIY solar panel measurement needs. We will walk through Voc and Isc but also perform voltage and current measurements while the panels are in use. I will also walk you through making your own custom MC4 test leads.

Note that the IDEAL 61-757 ($133) is very similar to the 61-747 ($90 - Lowes special). Major differences are the 757 goes up to 1000V while the 747 goes up to 600V. In addition, the 757 has a low impedance AC Voltage mode for very small voltages. Neither of these features are likely to be important to DYI folks.
Agreed, I have the 61-747 👍 and have found Lowe's to be the cheapest. Thanks for the feedback!
Very helpful, thank you!
Thank you. I just purchased my first solar system
You make some good videos.
You could also
Subtract line voltage from output voltage what should be 274
Then divide buy line voltage multiply by 100 and that will give you the actual percentage that is going into the grid
Which will correspond exactly with the first test
That proves that solar could only put in less than 20%
Ohm's law got to love it
Now take your new vom with amp clamp
To the meter on your house
Measure amps
Turn off the main
Measure line voltage
Multiply the two and that will give you the actual watts that are going into the grid
Good one🙂
It doesn't look like that meter has inrush?
Hello is there anyway to contact you directly.
Unrelated but is it possible to use one solar panel to charge 2 delta pros at same time ? Like with some kind of splitter.
It seems likely that the charge controllers in the 2 Delta Pros would fight each other. Each wants to control the solar panel voltage and current to set maximum power points (MPPT), and they likely would want different voltages and currents. It would likely be more successful to charge one from the solar panel, and run the output of that one to the input of the other to charge it.
It might be possible to disable the MPPT function in the Delta Pros. That would work if they were connected in parallel to the solar panel. But you would lose the efficiency provided by the MPPT function.
Can you put a link to the panels you use? Thanks

@@everydaysolar thank you sir.
Has anyone found the clamp meter for less than $131? Thanks!
I think Lowe’s has it for $89 in my area.
@@everydaysolar Thank you for the video and response, I'll check it out at Lowes.
@@everydaysolar Menards and Home Depot have it too
