[RE-wrenches] would this work?

[Larry Crutcher, Starlight Solar Power Systems]

All MPPT controllers I know of all need battery voltage to operate.

ok wrenches... here is a hair brained idea i came up with.
 
i have this customer with the grundfos pump being powered, array direct by 10 astropower 75's in series... so around  170 vdc.
 
what would happen if a hv mppt charge controller were paralleled with the panel output feeding the pump?
would the cu200 & charge controller mppt algorithms fight each other?
 
thanks,
 
todd
