<div dir="ltr">Bill,<div><br></div><div>Watch out for the 480 delta with the SMA inverter. Even though the product literature says it works, it doesn't. If there's ever a ground fault (PV system or customer facility wiring) on one of the 480 legs, the other two legs will jump to 480V to ground (with much higher spikes along the way) and blow up the varistors on the inverter output stage which are not rated for this condition. We learned this the hard way with 10 out of 24 inverters suffering complete failures on one project shortly after they were installed. We're talking catastrophic component failure with bits of varistor all over the inverter boards and adjacent components scorched. In the end, we installed a 750kVA 480 wye to 480 delta isolation transformer to provide a reliable ground reference for the inverters. In the process of solving this problem, we learned of several other sites with the same issue...</div><div><br></div><div>Best,</div><div>Blake</div><div>Sun Light & Power</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Apr 18, 2019 at 3:44 PM frenergy <<a href="mailto:frenergy@psln.com" target="_blank">frenergy@psln.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>Wrenches,</p>
<p> I'm tackling a huge residential system that requires
back-feeding the grid at 480 volts, delta (no neutral, right?).
We're going to GT 30-50 KW. The SMA SB30000TL-US-10 is one of the
few inverters (apparently) that can do this, which I'm planning to
use. The inverter can be fed up to 1,000 vdc,OC. 1,000 volt array
is new to me. I assume they have to accept the high voltage
because its a 30K inverter with only 2 MPPT strings. My question:
Other than not getting fried during installation, what's different
about wiring the array or anything else on the DC side? I don't
see anything in our current (2014) code cycle on this that's
different than 600 volt.
Tips, advice?<br>
<br>
Any links, past webinars, whatever else also helpful
would be welcome. <br>
</p>
<p>Thanks,</p>
<p>Bill<br>
