Hi Guys, let me clarify.

Coincidentally the image above of the solar controller is exactly the one I am using - CMTD

I am using the connector where it says Leads and has the light globe on the end.
That is where I have connected the two outlets to power the motor and the micro processor

I know it works, why I asked the question was because my understanding is that this outlet
can be used to power other components once the battery is full with so called surplus power?

I know that the correct way of connecting this up should be directly to the battery but because the
needed power is very low I have done the connection to this outlet.

So back to the original question - Is this  going to be OK using this method?

Hope that has made it clearer.

The light bulb marks the load terminals. 

  1. Your panels connected to the first two terminals.
  2. Battery connected to the middle two terminals.
  3. loads connected to the load terminals.
  4. It is working fine.
You are using the charge controller a way it was designed to be used. Your good to go.

If later you decide to add more DC loads your need to make sure you don't overload the load terminals, there is a limit.  If you ever want to power heavy loads you would need to do so directly off the battery.

You're very welcome! Hope it was of help.

Solar is like the wind. It may be free, but putting it to work isn't!
