<div dir="ltr"><div>Mark</div><div>The smallest battery I have used is the Blue Planet 8 kWhr. its a half stack in there cabinet with a 10.8 k PS-3 inverter system with about 6 k on the roof, 8 K is not much but this particular customer only uses this for some low demand power consumption that must operate. It is less expensive to go with 16 kWhrs vs 8 at a cost per watt also</div><div>Jerry<br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sat, May 23, 2020 at 10:37 AM Mark Frye <<a href="mailto:markf@berkeleysolar.com">markf@berkeleysolar.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">In the way back machine I remember being at a product roll out meeting <br>
for the brand new Outback FX inverter. I asked the engineer, what was <br>
the smallest battery bank that could be connected to the inverter. He <br>
said on the fly that probably you would want the battery to "weight" at <br>
least as much as the inverter. I thought that was a great answer.<br>
<br>
Fast forward, with a 4000w Outback Radian, AC coupled with 2000w of PV, <br>
what is the smallest Li battery I would want for stable operation?<br>
<br>
My loads don't really need more than 40ah of capacity.<br>
<br>
What is the latest best practice on this?<br>
<br>
Thanks.<br>
