I think what Grant t1 was referring to above was the load current. For instance my Projecta
solar control is also a battery manager. Standard setup, 20A
solar controller, battery connected to the battery terminals,
solar panels to the
solar terminals, load to load terminals.
It monitors charge into and out of the battery, catch 22 is the controller is rated at 20A, if you try and draw more than 20 amps from the battery the overload protection trips and disconnects the battery, therefore in this case the controller not only needs to be dimensioned on the
solar input but also on the peak demand.
