Little confused, 12v vs. 24v solar
I've got an existing 12v solar array with 1x 130 Watt and 2x 80 Watt for a total of 290 watts @ 12v, fed to a 30 amp MPPT controller (Rogue MPT-3024). I bought what I thought was going to be a 200 wat...

simple questions
what is VMP pf the 80w panels..example 17.2
what is the VMP of the 250w panel .. example 34.5
if the toatal VMP of both 180 panels is really close to the VMP of the one 250w panel
then yes the (2) 80's series-ed together might work paralleled to the the 250
its about matching panel voltage when parallel
series panels must be identical "AMPS" so identical panels are used
parallel panels need matching "voltage for the MPPT parallel circuit input to work correctly
the max will be 410w IF it can work
you are running (3) panels parallel because the voltage is close
the 130 is odd man out in a new configuration with only one controller
like was said Maximum use, would be to replace the Rogue with a new PWM controller, and connect the NEW 250w panel with the rogue with and new wiring for the that panel
you would have two systems connected to the same batteries
that would give 310 + 250 for 560w total
