<p><b>New page</b></p><div>[[File:AccumulatorChannel.png]]<br />
<br />
HTML entities are fine here: (<tt>&amp;Sigma;</tt> → <big>&Sigma;</big>)<br />
<br />
Define all your required channels, put this all together and you should have the following definition:<br />
<br />
[[File:AccumulatorChannelTree.png]]<br />
<br />
'''''Please note:'''''<br />
* The real sensor channels storing the data for P<sub>AC</sub>, P<sub>DC1</sub>, P<sub>DC2</sub> etc. must be defined '''for each''' inverter!<br />
* The grouping channels <tt>Inverter efficiency [%]</tt> and <tt>&Sigma; Pdc [W]</tt> must be defined only '''once'''!<br />They find out their correct child channels from '''their position in the channel tree''' on request.<br />
<br />
If you want to have a more detailed result for efficiency, set the valid from attribute for example to '''95''':<br />
<br />
[[File:AccumulatorChannelChart95.png]]<br />
<br />
Here you can see, that the efficiency (black dashed) is after noon about 97%!<br />
<br />
All values below 95% are "raised" to 95%, so just ignore them until 8:00...<br />
<br />
