-This occurs because the PPT controller moves Vpanel toward Voc to reduce current when less is needed but battery voltage is high, as in late Absorption .  Counterintuitively, some load to the system can drop PV voltage (and therefore CC temps) to lower levels.((http://forum.solar-electric.com/discussion/comment/256896#Comment_256896))
+This occurs because the PPT controller moves Vpanel toward Voc to reduce current when less is needed but battery voltage is high, as in late Absorption .  This occurs because the greater the voltage conversion the more heat is produced.  For this reason, and perhaps counterintuitively, adding some load to the system in Absorption can drop PV voltage (and therefore CC temps) to lower levels.((http://forum.solar-electric.com/discussion/comment/256896#Comment_256896))
