Adding 80W AKT Solar Panel & 10A charge controller to national luna split charge sys.

[JimmiSashimi]

Hello Hubbsters,

I am about to get an 80W AKT Solar Panel Kit with 10A charge controller for my defender 110, 300 tdi before leaving for Africa in Jan. 1 year over land.

Can any one recommend best set up to add the solar panel into the national luna split charge system that is already installed?

I am hoping I can simply add the solar power feed from the solar 10a charge controller directly to the main battery terminals (as a standard recommended AKT installation). Is the theory sound that when the engine is off then the solar charge controller will do its job BUT when engine is running the national luna split charge system will kick in and the solar charge controller should hopefully turn off by sensing higher voltage (i.e. sensing the battery is "fully charged" - despite the voltage that is turning off the solar charge controller would actually come from the alternator)?

This way the 80w solar system would infect keep both batteries at close to full capacity and split charge solenoid would do its "5 minute on after main battery receives charge" cycle.

Any thoughts before I cause damage?

Perhaps Plan B would be to wire the solar charge directly to secondary battery (including the 10A solar charge controller)?

FYI - System is 2 x PC1500 Odyssey batteris (AGM).

Many thanks,
JS
