I got one of these 150A meters and tested it with the 12V adapter on the picture just to make sure it was working.
The screen turns on instantly and displays the correct voltage.
Surprisingly, when I try to use it with a 100W solar panel (where I measured about 18V with a multimeter), the meter doesn't turn on.
Same with a Rutland 913 marine wind turbine that also delivered about 18V when I did the test in strong winds.
Does this meter need more amps or something?
Thanks
