Midnite Classic 150 limits

My current system is:
6 240 watt schott panels
midnite classic 150
magnum PAE4024 inverter/ME-RTR control
600amp/hr forklift battery
I have a chance to buy 6 more of these panels for $1000
can I add them to my system without adding another charge controller?
the 6 I have now face south, the next 6 would face east.
Midnite sizing tool says 2611 max watts.
I cant afford another controller right now.
What are my options?
Thanks for the help folks.

There is one change I think you should make, however. Change your array configuration to a string length of 2. That will give you a string Vmp of 60 volts rather than the 90 volts you currently have. The reason to lower the voltage is it makes the controller more efficient which means it can handle more power before it melts. Realize that when you reach the power handling limits of the Classic, it limits its output to prevent itself from melting. It is not a good to design a system where the controller spends most of its time on the verge of melting.
Doubling the array AND lowering the string voltage will both have the effect of requiring a heavier cable between the combiner and controller. I hope your array is not too far from the controller.

I have 6awg solid copper wire running from the combiner to the controller All inside the building, I believe it will handle the amps.
Thanks for the reply.

I'm running 3 strings of 3 because I didn't know any better.
I'm learning.
Thanks for the reply.

Once you go well over ~2000 watts, 48 volt systems are the logical choice according to my readings. Something to keep in the back of the mind perhaps. Wires lose a lot less power at higher voltages. Perhaps I should refrain from certain suggestions...
My different oriented panels aren't on the same controller though. Maybe someone doing that (@softdown ?) will chime in.
Main daytime system ~4kw panels into 2xMNClassic150 370ah 48v bank 2xOutback 3548 inverter 120v + 240v autotransformer
Night system ~1kw panels into 1xMNClassic150 700ah 12v bank morningstar 300w inverter
Every time I used the Sharp panels wired in strings of 3 (105 volts) or the Sanyo HIT panels in strings of 2 (113 volts) on my 24 volt system I logged much higher temperatures and had several over temp occurrences with the Kid controllers. I do not have excessive power or heating using the lower string voltages.
I have used as much as 3200 watts of panels on the Classic 150 controllers and 1200 watts on the Kid controllers in my sometimes fowl winter weather, I’m only a few miles from the Pacific Ocean and have severe foggy/overcast weather in the winter months, I switch out extra panels for extended fair weather.
