Morning! My father-in-law and I are doing a cabin project together. We are building a 512 sq ft cabin with essentially house construction. The cabin will be a retirement home later, as well as an escape of sorts now. This will be in Northern Arkansas, and Solar Irradiance calculations appear to range from 2-6 ish, depending on the time of year. I really need some help organizing my thoughts around this. I am anticipating a 48v system. Please help?
From a load perspective, we are looking at trying to run panels, batteries, and an inverter to power these items. There is no grid power option. We have a 25amp 3500w generator we could tie in in times of low sun coverage but we REALLY want to avoid if possible. Currently, we anticipate using the cabin in 3-5 day bursts, typically a Fri/Sat/Sun but sometimes we get lucky and can get a 5 day or so week out there.
-Approx 0 to 24 LED bulb lights that are either all off or all on depending on how rowdy we are getting.
-approx 15 cu ft refrigerator that would remain on
-propane stoves electronics always on
-coffee pot for 2 hours a day max
-Mr.Cool DIY 12k 120v unit during hot summer months, mostly running at night but some midday as well
-Possibly a second Mr.Cool DIY 12k 120v Unit that would run the bathroom and bedroom area (running the DIY Multi Zone Would require 230v service). Might not ever run concurrently with other unit, basically cooling Bedroom at night.
-1 ceiling fan
-small LED track lighting throughout
-plugs throughout the house that will charge a max ever of 4 iphones simultaneously, though typically only 2 at a time, 6 hours max in a day.
-plugs throughout the houe that will charge a max ever of 2 computers simultaneously, though typically only 1.
-tankless propane hot water heaters electronics that are always on
I think I have everything there. Or for the most part. I am anticipating picking up with 100 or 200ah lithium batteries, have seen the stuff on the SOK and Ampretime Batteries and am ready to pull trigger on parts, basically from you guys recommendations. My FILaw and I have good working knowledge on how to handle the AC wiring from the home breaker box out in the construction, but this solar calculating and planning is eating my lunch. Any help would be much appreciated.
