Our cabin recently was subjected to multiple days of no electricity during
to a bad storm taking out trees and power lines
I would like to set up a generator to run the following
1) well water pump 3/4 hp (120v)
2) refrigerator (120v)
3) freezer (120v)
4) hot water heater (240v)
5) stove (240v)

I would like to set it up so that is one appliance is drawing power,
everything else waits.
It would also be nice to set up the chain in the order listed above

It should also be noted that:
a) the stove is optional since there is a great fire pit where food can be
cooked and hot water heated in large enough quantities for hand and
dishwashing and sponge baths.
b) the hot water heater is big enough to hold enough water from one
heating cycle for all daily hand and dishwashing needs + couple of showers.
Which means that unless there are more than 2 people using the cabin, it
would only need to run once - possibly in the morning to start the day
c) the freezer only needs to run once every 2 days
d) the refrigerator only needs to run once a day if access is controlled,
otherwise twice a day will keep it cold enough
e) the well water pump only needs to run if water pressure has dropped
low enough to trigger it.

I already have an electric start generator to run everything at the same
time.
But I would prefer not to load it to the gills at the same time,


So I'm looking at
1) a box that will make sure that when the generator is going, it will
sequentially feed the 5 devices and then shut off by itself when there is no
demand...
2) If the generator is going, then IF a higher priority device wants
power it can bump of a lower priority one. After which the bumped device
gets serviced.


Any help and suggestions are appreciated

I hear there may be a few NASA engineers in need of work shortly.

If you have the budget I'm sure you can find someone to design the
system, write the software,find the parts, assemble the parts, and
install.
