I am getting conflicting information. I have a smart solar 100/50 charge controller with four 170 watt panels connected in parallel. My dealer says I am pretty much maxed out in regards to input current. When i asked the panel manufacturer they said that each panel can put out up to 9.4 amps (i assume that would be at 18 vdc). So they said that by adding the fifth panel that would be only 48 amps.
I am thinking If you consider the output current (assuming no loss) when connected to a bank of lithium batteries the output voltage in bulk mode would be 14.4 vdc. With five panels connected the output current would be 59 amps. Am I correct here? Would this be exeeding the capacity of the controller? Does current limiting come into play?
