    Joel,<br>
    <br>
    I would be very interested in further updates on your Envi
    experience.<br>
    I bought one to use in my PV installer workshops and used it for<br>
    the first time back in May.<br>
    <br>
    I'm really hoping that future software, theirs or 3rd party, can fix
    two<br>
    glaring issues I have with this unit.<br>
    <br>
    One is that I can find no cumulative kwhrs, only cumulative kwh
    cost.<br>
    The other, a biggie in my opinion, is the readout labeled
    instantaneous<br>
    energy....gee, isn't that a lot like POWER?<br>
    <br>
    Other than that, it seems to work as advertised. <br>
