I have a 430 CPMY with lots of room in the lazerette for batteries.
I do not currently have an inverter system but want to install a solar system, primarily for dual 12V / 110 V fridge.
My simple solution is as follows and want to know opinions on feasibility.
The installation will be with proper wiring / connectors / fuses / controllers etc.

1) Install 2 600 watt panels on the hard top and run cables to the lazerette.
2) Install 1 400 A/H lithium battery
3) Install 1 4000 watt pure sine wave inverter.

I then want to install a 30 amp power inlet into the side panel of the cockpit and connect that to the inverter.
Then simply run a shortened shore power cord from that inlet into the main shore power inlet that is used for the shore power connection.

This should then supply 110 V to my main panel when switched to shore power.
I should then be able to run any 110 V circuits from my DC panel.
This would include my battery charger for the main start batteries if required.

Does this sound feasible. primarily used for the fridge / coffee machine / TV / lights.
I would still run my genni for any heavy loads such as stove top / hot water when required.
Feedback would be much appreciated.
