Mr Wizard, I ended up buying and installing the cheap DCM meter you have and it seems to be working out pretty well. During the last several days of putting the finishing touches on my solar install I've been keeping a log of my voltage as shown on the DCM and on my DVM right at the battery. It consistently shows .15 volts less than my DVM shows. I can live with that as it's consistent. The amps are a little off, showing 2.4 amps charging when there is actually no charging going on and virtually no load. I think that's just a matter of calibration which I just haven't had time for. I have to go back and re-read the Chinglish instructions again and figure out what I need to do. In any case I just wanted to thank you, and everone else on this thread who gave me advice on this. You are all so helpful
