how to wire two different amp Smartsolar charger controllers
Hi @ronanddeb
Just parallel them into the same batt terminal/bus on both +/- sides.
They should work fine individually, but the newer Smart firmware should be able to sync their 'charge states' if you link them via bt. Try it..
I have done this very simply as the previous answer but put a seperate breaker in for each before joining up so you can seperate the inputs if needed, i have then put another breaker after that so you are protecting the wiring as a whole, (belt and braces)
They each work fine and there is no conflict at all.
