The project I would love to accomplish, is to harness the creek to produce hydro electricity. This my second attempt to generate electricity from water. The other is my homebrew turgo turbine.
It is very fulfilling to be self sufficient, I am lucky to have the location I have, the water oozes from the hills here in western Virginia.

Because the charge controllers are remote from the house. I keep a calendar next to them. When I remember (which is not as often as I should), I record the accumulated amp hours on the charge controllers on the calendar, then reset the values to zero. I then average the reading across the days from the previous reading.
Also, many times we produce more power than we need and the charge controllers will go to float, effectively wasting energy and making the amp hours low.
I wish I had a meter, so that I know my actual power usage. Currently, I can only estimate based on the amount of power we generate.
