<div dir="ltr"><div>Hilton, Wrenches</div><div>As I recall Tesla does not recommend their battery for off grid applications, they need to be connected to the internet and without that there may be warranty issues. I don't think that the off grid world and daily cycling would work well over time either. How would you jump start the power wall if it died do to low voltage cut out, a genny might work if it connects and stays connected this might also affect the warranty. <br></div><div>Jerry <br></div><div>NABCEP PV inspector <br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sun, Jul 19, 2020 at 9:02 AM Hilton Dier III <<a href="mailto:hiltondier@gmail.com">hiltondier@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

<p><font face="Times New Roman, Times, serif">Greetings, Wrenches,</font></p>
<p><font face="Times New Roman, Times, serif">I have an off-grid
client who has been reading the buzz about the Tesla Powerwall
2.0. I have been reading the data sheets and manual for it and
it appears to be AC coupled only. There was talk of a DC input
version, but apparently that fell by the wayside. I try to be
agnostic about technology, and I'd be willing to subcontract a
Tesla-approved installer if, in fact, this was the best
solution.</font></p>
<p><font face="Times New Roman, Times, serif">Does anybody have
experience using the Powerwall 2.0 in an off grid PV system? Is
it AC coupled only? Can it take generator power without barfing?
What is the lead time on these?<br>
</font></p>
<p><font face="Times New Roman, Times, serif">Many Thanks,</font></p>
