I recently purchased a Renogy 800w kit that includes 8 100w solar panels and a 40 Amp MPPT Charge Controller. This controller will allow input of 800w at 24v but only 400w at 12v. I need to use it on a 12v RV system.
Do I need two controllers, one for each 4 PV panels or can I split or step down the output to 12v?
If I use 2 controllers at 12v, can I attach them both to the same batteries together?
If I use a 24v to 12v converter between the controller and the batteries will the controller still manage the charging properly?
Or should I charge the batteries at 24v and put the 24v to 12v converter between the batteries and the load?
Any input or ideas would be greatly appreciated.
Thanks.
