Ok, yeah
There was a very clear and major miscalculation running through that whole first post that I realized. I didnt take into account the amperage its going to draw at 12v DC, just at 120v AC. Essentially missing the 0. And throwing off everything by ten fold. Damn.
Never to fear. So a major revamp of the plan needs to be made here. If things are gonna be drawing 10x more than what I anticipated, heh, Im doubling the battery bank. And going with a cheaper gel battery as opposed to the AGM in order to compensate.
So the bank will be in the neighborhood of 500Ah.
Air conditioning. Gonna have to scale it down. So as oppposed to that 7000 BTU ac unit I may have to go with a personal space air conditioner such as the Amcor Personal Air Conditioner APC2000E. Power Consumption: 250W/2.1A. So 2.1 Amps at 120v will draw 21 amps at 12v. Thats not too bad.
or
FREECOMŽ RCS-M1000T 4,000 BTU. Power Consumption: 4.1 Amps at 120v so 41 at 12v, also not bad.
But the bigger unit, the freecom, is rated for 100 square feet. The smaller unit is designed to be a personal space air conditioner. Dinky units. Ill have to change up the way I was gonna use them. These things will have to be right in my face as Im sleeping. Not too big of a problem really, just mount it closer to the bed. And possibly change the way I wanted to work them. As opposed to having AirC for the duration of the night, it may need to be on an as needed basis.
Nevertheless, even if I wanted to run it solid....20 amps over 8 hrs= 160Ah. Same as before, I dont wanna draw the bank down too much. 160 x 2 = 320Ah. Good. Even though the inverter is gonna suck up its percentage, with a 500Ah bank I should be good to run it all night if neccessary without croaking. I basically just had to settle for a smaller unit. Itll suffice.
Now, as far as cooking goes, a 1200 watt electric frying pan will draw 100 Amps out of the DC. Ouch. Umm... I guess we can work with that. Its not like ill be running the frying pan for hours on end. 25 Minutes at the most. Still feasible.
Plus I can get an 800 Watt microwave, 66 amps at 12v thatll run for all of what? 4 minutes?
Um. What else. The TV and laptop and radio will draw what they draw, cant really downsize in that area but the doubling of the battery bank will compensate. I didnt intend on using those for an extended period of time either.
So, fixed up the draw calculations and adjusted accordingly. Im still confused in one major area:
How do I determine what the solar charge controller and the shore power charger will need to be rated at???
Matter of fact the whole charge process confuses me. I really need to look into this.
At what pace will a 200watt solar panel at full power charge a battery?
