<p>Discover AES meet residential UL 1973 and UL 9540 for insurable homes. Not sure what the IEEE spec is but would like to know.</p>
<p>A piece of cake to stack up to 20 of the 7.5 kwh. Also a piece of cake to configure with XW+ or XWP. The 6.8 kw xw's will supply 8.5 KW for 30 minutes. A master and 2 slaves would be overkill. Extremely easy to configure and AES is closed loop into xanbus. Just set time and date. Radian would be nice also but it is still open loop and all the set-points have to go in along with other config.</p>

<div dir="ltr">Hi Wrenches,
<div> </div>
<div>I am working on a design for an all-electric home whole-house backup. The utility is requiring either an inverter listed to IEEE 1547-2018 or utilize an effective grounding transformer with associated relay control system. Im unclear whether the grounding transformer is on the customer side or on the utility side, but I'd prefer to avoid this if possible.</div>
<div> </div>
<div>I probably need ~20kW of continuous backup in this case. I prefer to have everything stacked if possible, but I may be able to split up my critical load panels.</div>
<div> </div>
<div>Has anyone worked through this issue? I was planning on Sol-Ark but they don't comply with the IEEE 1547-2018 quite yet. I'm open to suggestions.</div>
<div> </div>
<div>Thanks<br clear="all" />
