A shunt between the battery and the power sources (wind turbines, solar panels, microhydro, your cousin on the exercycle), tell us the current being generated, and a voltage divider reads the voltage of the battery pack. If another shunt is placed between the battery and loads, power consumption also be tracked. From that we can calculate the watts being produced.
With our SD Card and RTC Module, we can calculate amp hours and watt hours, and save them to a sd card.
We also can record weather data, like temperature, humidity, barometric pressure, wind speed & direction, UV index, and much more.
We give you the ability to upload your sd card files for charting and graphing your data. Real time reporting options with ethernet and wifi are available to the internet or optional local Raspberry Pi web & database server.
