, generator, and some solar panels
. Most do not have lithium batteries but that is usually easily solved
by getting the lead out. A reasonably sized lithium bank in 2017 is 9kwh to 20kwh.
For me one of the first design criteria for my boat was the removal
of the gusher manual pump
powered head. I retain the new holding tank for hydroponics or yet undecided uses like rainwater filtration or holding.
I can relate my experience to the original posters question and Lepke does the same. If others outfit and equip in 2017 with technology from 1917 there is little to enlighten or convince them. 12v x 2 100ah lead acid batteries yields a 2400 kwh battery
bank with only 1200 kwh usable. In their reasoning 1200kwh is adequate for a sailboat which in the case of using a modern appliance it is not. Some are even appalled by the thought of having to start a generator like denverd0n who sounds like he need to actually use the facilities.
What it comes down to for the modern liveaboard
is what they define as an acceptable level of power on their boat or what they consider well supplied electrically speaking. So if the in terms of the OP's question on incinolet on a boat the benefits far outweigh the hassles and are a very viable alternative.
It appears Lepke is even just running his off lead acid and an alternator from his main engine
. So probably based on what what an acceptable C rate of the batteries to handle the charge or cycling of power through the batteries is what it comes down to.
