<DIV><BR></DIV><FONT face=Verdana>One key requirement for the installation of
grid-tied PV is that it be connected to a dedicated circuit. This is
mandatory to prevent circuit conductor overloading under certain fault
conditions. A DIYer may be inclined to connect his PV into an existing
circuit. We even get inquiries about putting a plug on the end of the PV
branch and plugging it into an existing 240vac outlet. <BR><BR>Very

<DIV style="FONT-FAMILY: Arial,sans-serif; FONT-SIZE: 10pt">Since the new
micro-inverters can be easily wired into the nearest 240 VAC circuit, odds
are this will be the new do-it-yourself project for homeowners.
However, odds also favor new round of outlaw solar systems that are not
inspected, do not have properly sized wires and breakers, and do not have
exterior utility dis-connects (although many states are no longer enforcing
this requirement).<BR><BR>So, it appears to me all the codes still apply
regardless of where the inverter or inverters are located, so are any of you
seeing an increase of these micro inverter systems installed by the
homeowner?<BR><BR>Jeff Yago<BR>DTI
