I purchased the same item on Amazon to track how much current is being drawn from my batteries. Very cheap compared to Victron battery monitor or Trimetric. Mine reads 0.00 when the solar panel is producing more than what is being used from the battery.
Meters, in order of increasing accuracy:
Turnigy, GT Power, Watts Up.
Video review.
Other countless and nameless gizmos from Ebay and Amazon are hit and miss, more often miss.
When very accurate meter like GT costs $40, it's hard to justify $180 for Victron and Trimetric. Display of my solar controller does "half" of the job, reporting real-time and total "in" activity for the day. The total is usually to my satisfaction, i.e. battery reached 14.6, dropped to 13.6 and stayed there for several hours. Don't have that teenager curiosity to explore how much watts my electric shaver or radio draw, and besides, I already know that :)
