<P><SPAN LANG="en-us"><FONT FACE="Times New Roman">Hello all,</FONT></SPAN>
</P>
<P><SPAN LANG="en-us"><FONT FACE="Times New Roman">My final gold is to charge batteries with a solar panel. For my tests, I have built a simple building; a solar panel and a room (see picture 1). The electrical network includes only 2 nodes linked together, one for the PV and one for the load. All my network are on the 24Vdc.</FONT></SPAN></P>
<P><SPAN LANG="en-us"><FONT FACE="Times New Roman">1) First test: No load, open circuit.</FONT></SPAN>
<BR><SPAN LANG="en-us"><FONT FACE="Times New Roman">At first view, the simulation looks good. The PV generates voltage according with sun intensity (see picture 2). The issue is the PV generates power too (see picture 3). It’s not supposed since there is no load (open circuit). More, the generated voltage is at the full charge value of 35V (Vopen = 43.5V). </FONT></SPAN></P>
<P><SPAN LANG="en-us"><FONT FACE="Times New Roman">2) Second test: Add batteries on the load node.</FONT></SPAN>
<BR><SPAN LANG="en-us"><FONT FACE="Times New Roman">Nothing happens. The PV reacts exactly like the first test. More, the load node voltage is zero. I expected the same value than the PV node since they are linked by a wire. </FONT></SPAN></P>
<P><SPAN LANG="en-us"><FONT FACE="Times New Roman">3) Some design details</FONT></SPAN>
<BR><SPAN LANG="en-us"><FONT FACE="Times New Roman">For the PV, I use the crystalline RMS1100 PV include on special component “building integrated-renewable”. </FONT></SPAN>
<BR><SPAN LANG="en-us"><FONT FACE="Times New Roman">For the batteries, I use the “Power sonic Batteries” include on “Power Only Component”</FONT></SPAN>
</P>
<P><SPAN LANG="en-us"><FONT FACE="Times New Roman">It will be appreciated to have some help for the design of my electrical network or some documentations. </FONT></SPAN>

<P><SPAN LANG="en-us"><FONT FACE="Times New Roman">Thank you</FONT></SPAN>
