we will not be much help as i am not an electrician - but we added 3 130watt kycera
solar panels with a 2512 blue sky controller direct to the
batteries - we do not have
wind (yet) -
we have the same set up as you with a freedom 12, and a house
charger but being a bit older we have a link 10
not sure where you are going to use your
boat but we rarely stay in
marinas (except for upcoming
hurricane season in trinidad) and when we do we do not connect to electricity unless we are running
power tools ( we do not have ac) -
probably not much help
just our opinion
