That old Trace unit sounds like a very old mercury contactor
regulator, just a simple on/off regulator with a 200 amp rating.<br>
<br>
You most certainly can have 2 or more pwm type controllers on the
same battery bank, this is very common. You may see<br>
one go to float and the other stay in absorption for a short time
because there's no way to truly synchronize them but that's not an
issue.<br>
<br>
You would likely need 3-60 amp controllers to handle that 12 volt
array, too bad he won't agree to rewire it.<br>
<br>
Good luck!<br>

<div>Hello Wrenches,<br>
</div>
<div> 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. <br>
</div>
<div><br>
</div>
<div>If anyone knows of any controllers that would fit that
or if running those in parallel works your advice would be
greatly appreciated. </div>
