All good advice, I would just like to clarify the water pump.  While the water pump may draw a lot of power when it is running, it doesn't run very long, and in all will not use a lot of power.  Think of it this way.  Typical 3gpm pump will pull maybe 7A.  A 50g water tank will be emptied in 50/3 = 17 minutes.  This can happen all at once or in short bursts over a couple days.  Either way it will be similar. So 17 minutes is about 0.3 hours, and at 7A the pump consumes a total of 7x0.3 = 2.1Ah.  Not much it the scheme of things!
