<p>We just did this, and I think as long as each disconnecting means
refers to the other multiple sources and their location, and the
directory refers these multiple sources, you are compliant with
NEC2017.</p>
<p>I guess I will find out..... <br>

<div>I believe it's perfectly fine to have multiple inverter

have an NEC code question on an upcoming project. It
is a home that has an existing 8 kW ground-mounted
grid-tied system. The owner wants to add another 10
kW of grid-tied PV. My question is about 705.12,
point of connection. Specifically section (D)(1).
That section states: </span></p>
<p class="MsoNormal"><span
style="font-size:12pt;font-family:Verdana,sans-serif"> </span></p>
<p class="MsoNormal"><i><span
style="font-size:12pt;font-family:Verdana,sans-serif">The
source interconnection of one or more inverters
installed in one system shall be made at a dedicated
circuit breaker or fusible disconnecting means.</span></i></p>
<p class="MsoNormal"><span
style="font-size:12pt;font-family:Verdana,sans-serif"> </span></p>
<p class="MsoNormal"><span
style="font-size:12pt;font-family:Verdana,sans-serif">So
if there are going to be two inverters on premise, do
the outputs have to be aggregated to connect via one
circuit breaker? This might be difficult to do as the
exiting inverter is connected via a different
sub-panel than the one that is planned to receive the
new inverter output.</span></p>
