[RE-wrenches] PWM Controllers in parallel

[Andrew Perkins]

Hello Wrenches,

                    I have a client who has a large 2000 watt 12v array that he said used to be hooked into an internal solar charger on his old trace. Never seen a trace with one of those in it but he claims it could do 200a. This internal charger has now died and needs a replacement. He is refusing to rewire his panels into a new configuration and their aren't many options for him out there. I did get him a Coleman Aire 400a Charge controller but it is more of a load controller and wants to be able to properly absorb is batteries off the sun. He currently has a c60 running only part of the array and now he is asking about running another c60 in parallel. Not quite sure if this would work or not but my gut feeling says no and there will be problems. 



If anyone knows of any controllers that would fit that or if running those in parallel works your advice would be greatly appreciated.
