I think that's a good approach.My personal choice setup would be to have en engine battery with a 1 way VSR to also charge the domestic bank when the engine is running. A mains powered battery charger connected just to the domestic bank and an emergency parallel switch to allow the domestics to start the engine if the engine battery went flat for any reason. I have rarely ever seen the need to charge the engine start battery from a mains battery charger unless the boat gets left unused for very extended periods.
But I can remember the days before cheap solar panels with no shore power.
There did seem to be a recurrent theme of taking batteries home to charge.
And batteries having short lives.
Affordable solar to keep the engine battery topped up through Autumn and Winter was a major improvement.
With shore power, a small maintenance charger for the engine battery can make sense.
