Hi Daryl,

You cannot parallel two C40's on the array side.  Once one of the units
starts to regulate, the other will see the total array current and become
overloaded or over-temped. Once it shuts down, the same thing would happen
to the first unit. You must separate the arrays.

Hello to all
Can I connect two c-40 charge controllers to one PV
array?  Such that each charges a battery string
seperatly?  

The reason for the question is to seperate two battery
strings to prevent thermal runaway.  

Daryl
