<p>Just reading more slowly, each inverter has to be on its on
separate disconnect means. You cannot put multiple inverters on
the same disconnecting means unless there are individual
disconnecting means upstream. <br>

<p class="MsoNormal"><span
style="font-size:12.0pt;font-family:"Verdana","sans-serif"">I
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:12.0pt;font-family:"Verdana","sans-serif""> </span></p>
<p class="MsoNormal"><i><span
style="font-size:12.0pt;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:12.0pt;font-family:"Verdana","sans-serif""> </span></p>
<p class="MsoNormal"><span
style="font-size:12.0pt;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>
