<p>Humm, so maybe a 3kwhr would work for my situation.<br>

<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>

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>
