How much solar should you get from 300W worth of panels of the Roof?

How low do the batteries have to get in order to get a decent reading from the solar charger?

Thanks.

If they are down to 13.2v or lower they should take the max amount they can, which will be way more than your solar can do.


What voltage are you seeing from the solar when charging. If it is low you won't charge fast and it might be stuck in float.
