Thanks to Steve for sending in this blogtip! Check out more info here.
We are rolling out our newest Wind & Solar Power Datalogger. 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. 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. A second shunt between the battery and the loads will also tell us our power consumption, and then we can calculate the approximate level of juice left in the battery. We have also designed a website where you can upload the contents of your SD card, and track your production (and consumption) over time. Although this was designed for those without internet access at the monitoring site, if you do have internet access, we offer real time data uploads.
