Revision as of 05:11, 31 December 2012

All of the OEM Replacement portable units and permanent home installation units appear to cost well over $1000. So I decided to look into other options such as building my own. At this point I have built one of three units. I have yet to add true energy monitoring but intend to add that feature. Stay tuned as I update this information.
