No it can be done, management of your watt usage is first, the biggest continual current draw is your water heater, I suggest going with a small diesel water heater and a flat plate heat exchanger like we did in our Newell. You can have endless hot water after you turn it on then when not in use turn it off, has a remote to do this. NOTE in the pictures you'll see blue plastic fittings this was just to experiment they have all been changed out to brass now its completed.
