<p style="margin:0;padding:0;"><span style="font-family: Arial; font-size: 10pt;">Folks,</span></p>
<p style="margin:0;padding:0;"><span style="font-family: Arial; font-size: 10pt;">I have a residential grid-tied customer in a net metered utility with a favorable TOU rate.</span></p>
<p style="margin:0;padding:0;"><span style="font-family: Arial; font-size: 10pt;">They could use about 10 kW of PV to offset 100% of their usage.</span></p>
<p style="margin:0;padding:0;"><span style="font-family: Arial; font-size: 10pt;">But, they also complain about regular power outages in their neigborhood. They don't want a generator.</span></p>
<p style="margin:0;padding:0;"><span style="font-family: Arial; font-size: 10pt;">With reliable AC coupling now available, do we yet know which is the more advantagous architecture; grid-tied, battery-based inverter w/ PV on the DC side via charge controllers, or grid-tied, battery-based inverter w/ PV AC coupled via grid-tied, utility-based inverter?</span></p>
<p style="margin:0;padding:0;"><span style="font-family: Arial; font-size: 10pt;">Your thoughts?</span> <br /><span style="font-family: Arial;"> </span> <br /><span style="font-family: Arial; font-size: 10pt;">Mark Frye</span> <br /><span style="font-family: Arial; font-size: 10pt;">Berkeley Solar Electric Systems</span> <br /><span style="font-family: Arial; font-size: 10pt;">303 Redbud Way</span> <br /><span style="font-family: Arial; font-size: 10pt;">Nevada City, CA 95959</span> <br /><span style="font-family: Arial; font-size: 10pt;">(530) 401-8024</span> <br /><a href="http://www.berkeleysolar.com"><span style="text-decoration: underline;"><span style="color: #0000ff; font-family: Arial; font-size: 10pt;">www.berkeleysolar.com</span></span></a><span style="font-family: Arial; font-size: 10pt;"> </span></p>
