i have the Renogy 100w solar KIT...i later bought 1 more 100w panel..soo i have 200 watts now...when i purchased KIT i upgraded the charge controller to the 20 amp mppt TRACER model....
my question is do i need to upgrade that 20 amp controller when i get 2 more 100 watt panels....can i use what i have if i wire them in series??? or combo series/parallel..
...........Thanks for helping a newbee...
