I live on a canal barge with 4 generic solar panels and need to update my old PWM system to a modern MPPT system.
There are 4 panels each of 255w parallel feeding 1020w in to a 12v system.
Isc 9.12A (as tested)
I have attempted to use the VE MPPT Calc which appears to indicate that the Blue/Smart Solar 100/30 would do the job- although I cannot input my particular panels.
The problem is that when I look up the characteristics of this controller it appears to be only good for 400w on a 12v system and I need 1020w.
Where am I going wrong? Please advise.
