As for battery use, for us it is almost entirely the fridge. We do sometimes run Camfro fans (installed two in the pilot house, one of which can be turned to ciruclate air to the berth), plus water usage and led lights (changed everything to led first year we had the boat), but pretty much everything else is run on the genny. 24 hours bill bring our bank of 4 GC batteries down to around 60-70%. However, we run the genny every morning for coffe and making breakfast, and also in the evening to cook and, if necessary, run the AC for a few hours before bed. Charger is on if the genny is on, and we are usually able to bring the house bank back to 80% during this short time. I hate running the genny while sleeping, not becuause of CO, but becuase we've had the strainer clog several times leading to a shut down and destroying the impeller in the process.
We also have the Sterling/ProMariner charger mentioned in another post and have been very happy.
