Hello
I need an up to 1000 mA and 12 v meter with datalogging capabilities into a .csv file for a solar project.

I use a Protek 506 for that.

blueroomelectronics, it dosent need to be very accurate maybe +- 100 mA +- 1 v also it does not need to be a datalogger as I can connect it to a PC. Also 1 sample per two minutes should be a good sample rate.
KMoffett, Do I need extra parts? Or do I only need the logger?
Since the input is +/- 10vdc you will need two resistors to make a voltage divider to scale the ~+12v down to +10V. You will also need a low resistance resistor (0.5Ω/2W) to convert current to voltage that the converter can read.
