Ammeter
New to solar and learning. I have a 100 watt system for a start and it would be desirable to measure how much electricity it is generating as well as how much I am using. Any low cost options? So...

My vote goes for a voltmeter but a good, reliable panel meter, not inaccurate garbage.
If you are conscientious, a gaze at a good voltmeter reading before morning activity will tell you if morning by morning you are waking up to lower and lower voltage. Then it's time to lessen the daily draw - whatever it takes.
A DROK 5-digit voltmeter
100% of these meters come adjusted (calibrated) so accurately that it's almost scary.
Yes, it has extra digits in the display. Ignore the 2 right most digits and you can bet your bottom doohickey that 12.39 is really 12.39 and it will not drift or get weird on hot days or cold nights.
I've gone through too many digital panel meters to count. Accuracy and degradation of same over time is an insane asylum. In the DROK, flip it over and note it's CENTRAL PROCESSOR. It utilizes a reference circuit unlike so may other meters. For the price IMHO, it's foolish to consider any other "economy" panel meter. Why three wires? If you don't understand: A separate circuit for panel LED illumination. The yellow wire is the + SENSE LEAD. Too much error with 2-wire meters.
