A little meter that has come highly recommended, and not very costly either, is the Digitek DT-2843R AC+DC True RMS Multimeter with Backlight and Temperature. The seller, apparently, is well recommended as well.
So, I figured I would pick one of these up for testing solar arrays, batteries, controllers, etc. Not to mention, a guy can NEVER have too many multimeters, can he?
I got it, shipped to me, for $44.00 USD. Now that I look back, I should have had it shipped to my address in Cambodia. It would have only cost a couple of bucks to do that. But, it won't take up much room
