ok i have a formosa 41 i live on. i have 3 rather large solar panels and i am planning to get a wind genny. i have a honda 2kw genny...lol.....i also have 2 battery banks--one is a d8--i call 3 man and a boy batt as it takes that many to lift it--is for starting the engine, a perkins 4-108. i use the house battery bank--4 of the trojan 6v golf cart batts --they are good and last many years when properly maintained----i have to recharge every day if i use the laptop every night---if i use in daylight and the batteries charge more than i use, i am golden. i use propane stove--as the electric ones use waaay too much electricity and are not efficient enough for onboard use...i rarely use a vacuum cleaner--i clean by hand the surfaces we know of on land as floors..lol--i have teak and holly soles....i use led lighting in the dark and many of those ar ebattery operated as i donot like to waste electricity --my exterior lights are solar powered ....walkway lighting--inexpensive and efficient...i have engine operated refrigeration i rarely use...no need to use fridge for keeping foods cold..lol....many keep well without fridge....there is a book--12 v bible---donot remember the name other than 12 v bible--get it----is white with red and black lettering...in many chandleries--could be nigel calder--donot remember--is excellent---all in all, you will need to use a generator to charge stuff--the sun isnt always strong enough to keep batts charged--my capacity is more than yours by more than 2 times--i have 2X235 amps with 235 amps each bank. the electric stove will not be supported by those batteries--you will need to adjust your usage and needs as you find the capacity not tolerable lol....sorry--but true.....if you are at a dock you will be fine--if on a mooring or at anchor, you will need to find a different method of doing things or add to what you have....
i am not being a smart ass but i found these facts to be true--without all the math ....
a small one burner electric hot plate will take 150 amps per hour ..thru the invertor....so in less than one hour you willnot be able to use the battery anymore----keep it simple--use propane--is more efficient and when used correctly with safety features is excellent...l e d lighting with internal batteries, the walkway lights with solar on each...i have my boats on moorings and i cruise in others boats regularly---have had boats since 1990 for residences---on docks and on anchor and on moorings--if i can help you with anything except math, let me know--the mathematical answer is waaay awesome--but folks like me cannot unnerstan it..lol...i just know what i can get away with and what works...goooodluck...
