Hi,
I'm setting up a SmartSolar MPPT150/100 to charge batteries with solar panels. Here is my configuration :
-2 arrays of 3 solar panels each (Voltec 385W, Voc = 43.3V each panel)
-2 packs of 12V batteries in series (so 2x 24V batteries)
I've got the Absorption and Float LEDs flashing simulatenously, and the batteries are not charging. I checked the manual and it indicates "Charger or panel over-voltage". I measured the voltage coming from the solar panels and it never exceeded 115V (which is less than the maximum PV voltage).
What could be the cause of this error ?
Thanks in advance.
