If the current capacity of the diversion controller is exceeded then you want the relay to switch in the big load. At that point the diversion controller will back off and pickup the difference. That is why I suggested the the relay controlled load be 50 to 75% of the pwm diversion load, so that whenever it turns on the pwm controller will be working, too.<o:p></o:p></span></p><p class=MsoNormal><span style='font-family:"Verdana","sans-serif"'>David<o:p></o:p></span></p><p class=MsoNormal><span style='font-family:"Verdana","sans-serif"'><o:p> </o:p></span></p><div><p class=MsoNormal><span style='font-family:"Verdana","sans-serif"'>David Katz<o:p></o:p></span></p><p class=MsoNormal><span style='font-family:"Verdana","sans-serif"'>CTO & Founder<o:p></o:p></span></p><p class=MsoNormal><span style='font-family:"Verdana","sans-serif"'>AEE Solar Inc<o:p></o:p></span></p><p class=MsoNormal><span style='font-family:"Verdana","sans-serif"'>P: 707 825-1200<o:p></o:p></span></p><p class=MsoNormal><span style='font-family:"Verdana","sans-serif"'>F: 707 825-1202<o:p></o:p></span></p><p class=MsoNormal><span style='font-family:"Verdana","sans-serif"'>dkatz@aeesolar.com<o:p></o:p></span></p><p class=MsoNormal><span style='font-family:"Verdana","sans-serif"'>www.aeesolar.com<o:p></o:p></span></p></div><div><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> re-wrenches-bounces@lists.re-wrenches.org [mailto:re-wrenches-bounces@lists.re-wrenches.org] <b>On Behalf Of </b>Larry Crutcher, Starlight Solar Power Systems<br><b>Sent:</b> Wednesday, November 30, 2011 8:49 AM<br><b>To:</b> RE-wrenches<br><b>Subject:</b> Re: [RE-wrenches] Diversion load for AC coupled system<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>David,<o:p></o:p></p><div><p class=MsoNormal>Ah..I think I see what you are saying.
