| Estimating my power usage for the coming day. I started the day out with a deficit of 1212 watts or 101 a/h (amp hours), do to the refrigerator and pellet stoves night usage. It is partly cloudy and cool. I figure the pellet stove will come on about 4 times during the day, as it has been doing all week. Using 400 watts for 4 min each start will be 16 minutes. Running 30 min each cycle at 20 watts (auger) equals another 80 watts for a grand total or 180 watts in round numbers. By having the blower disconnected and using a sterling engine electrical usage is cut by about 60 %. This and the refrigerator are power usage's that are essential. 180 watts divided by 12v = 15 a/h The refrigerator uses 1.2 k/w (kilowatt hours) per 24 hr period. Usage for the day ½ = 600 watts or 50 a/h (1k/w = 1000watts) grand total of 780watts or 65a/h. Computer time for writing this article say 2 hours @ 28 watts per hr = 56 watts more or 4.66 a/h. The importance of amp/hrs. is that the batteries capacities are rated in a/h as is the e-meter which monitors the batteries. Grid electricity is figured in watts, kilowatts, megawatts, etc. My usage is now increased by 56 watts plus I have a deficit of 1212 watts from last night, giving me a grand total of 1992 watts or 166 a/h. Now that the necessities are out of the way I can figure the little things like laundry, cooking, and entertainment. I have a stabre washer which is very economical on water and elect. I would like to use the crock pot to cook ham and beans while I'm out and about. I also need to make a loaf of bread. I have built an electrical chart of all the appliances that I own. And use it to figure my consumption. Washer 150 watts per load or 12.5 a/h. For the crock pot 550 watts per pot of beans or 45.8 a/h the bread maker 375 watts per loaf or 31.3 a/h bringing my total to 3066 watts (3.06 k/w) or 255.5 a/h. I need a cup of coffee!! 60 watts Ooh!! 3126 watts or 260.5 a/h. Skip the toast!! 36 watts or 3 a/h. In this partly cloudy weather I have been averaging around 2.2 k/w a day elect from the sun and about 25a/h a day wind. Equaling 25 x 12 = 300 watts + 2200 watts = 2500 watts @208 a/h, giving me a deficit of about .6k/w. I will have to hope for better sunlight today. When one has a deficet like this, they can carry it in their storage for a few days and see what happens, or they can fire up a generator. (which I don't own) lets wait and see how the day turns out. If need be I will use less tomorrow and make up the deficit then, as it is suppose to be sunny. The washer uses 15 gal of hot water from a 120 gal solar hot water tank which is @ 104 degrees reducing the temp to 84 degrees. With good sun the temp will rise to about 120 degrees by late evening. I would like to use the jet tub this evening if the water is hot enough. It uses 40 to 45 gal of water and will need to be 120 or greater to keep from kicking on the aqua star propane, demand hot water heater that is a backup to the system. I hate to use propane if I don't have to. The tub uses 175 watts every 10 minutes. Sure would be nice to go at least 20 min. Showering runs the 12v pump which don't use much elect. I don't have a meter that measures my actual usage other than a watts-up, but it only measures 1 item at a time. So it is hard to figure my losses, between the inverters and the batteries to come to full charge. This cost about 20% of my charging or about 600 watts or 50a/h gives me 3726 watts total or 447 a/h. Looks like I will get 3k/w solar, but under 10 a/h, 120 watts wind until the prevailing wind kicks in later tonight for a total of 260 a/h..447-260= -187 a/h My e-meter says that I am actually down -135 a/h. Pretty close. Think I'll use the hot tub for 20 min. almost sun down and the wind is coming up check then for final numbers. 3.4 k/w from the sun and e-meter @ 113. Lost 2 a/h. Good day! Will have plenty of sun tomorrow. Hope to equalize as I won't need much elect. Maybe vacume. Will use 20a/h maybe tonight on x-m radio and florescent lights. I have a real neat 12v led lite that uses 300 miliamps, lights up nice for relaxing or when elect is in short supply. Water at 130 degrees, jet tub filled, Aaaaah!!!! love that electricity!!!!.==erne |
