Looking for advice.

I have a 456 year 2000. This boat does not have an inverter just battery charger. I want to add solar to avoid running geny (or at least limit the time it is running) while anchored. The purpose of solar addition is to operate my fridge (which is ac only) and maybe another outlet for computers etc.

I am trying to decide if I should replace battery charger with a new unit that is a battery charger/inverter, thus tying solar into the boats entire electrical system, or just keep the present design and add an inverter and enough batteries to run the fridge independently while not on shore power.

I have lots of room to mount solar, house batteries and could easily arrange inverter installation beside my fridge enabling me to plug into shore power/geny or switch and plug into inverter/solar.

Any past experience/ideas will be appreciated.

Thank-you
