[RE-wrenches] GFP and multiple charge controllers

[Nathan Stumpff]

Wrenches,

In a job coming up I have a customer with an existing FM60 controller,  520 watt (!!) array. We are doing a ton of work, including adding a 4 kW solar array with Classic 150 charge controller. I am trying to figure out how to handle the GFP.

For the Classic, I need a 90 or 100 A output breaker minimum. 80 A is not an option. The OutBack dual GFP is 80 A, and so it not an option.

Is there a 100 A GFP breaker assembly I have just never seen? Is there a way to use the Classic's GFP to run an external relay via AUX (to trip the FM60 output breaker at the same time)? Any ideas?

Thanks,
-Nathan
