I bought a Renogy Rover Elite, 20 amp, MPPT solar charge controller.
The manual shows:
Max solar input voltage is 100VDC.
Max solar input power is 12v @ 260w - 24v @ 520w. (I am charging a 12v LiFePO4 battery)
Does this mean I can't use more than 260 watts worth of panels?
I recently purchase three (3) of the BougeRV, 180w, 9bb panels. I was planning to use two of them for charging this battery and the other panel for a different purpose. The BougeRV panels show the following specs:
Voc - 23V
Vmp - 19.2V
Short circuit current Isc - 10.23A
Max power current Imp - 9.38A
What I don't understand is if I put these panels in series I'll have Voc of 46V, which is less than half of what this controller is rated to handle, but is the max power input cutting it too close for a 20 amp model? Did I make a poor choice in charge controllers, limiting me to using only one of the panels at a time?
Sorry if this a really dumb question and thanks in advance for anyone who can help me understand my options.
