Thanks. Will get a 4-digit. 3 digits inaccurately rounded will do more harm than good. It's for my friends, not for me. My solar controller has a very accurate display.
You do have to get the correct 4 digit ones or they wont be accurate. Do you want to read 12.5 when it's actually 12.41? Or do your want to adjust it and read what it really is? I never bought any 3 digit so mex knows about them but I'm betting if you buy the same type but in a 4 digit you will get what I just described. They say right on them accuracy + or - 1% but they aren't that good.
I consider the small 4 digit models that I bought junk, but then I want to see what it actually is. Anal? Maybe but......
I bought the larger 4 digit that is adjustable on Amazon.
This is the Amazon ad.
