so now, we have surge pricing, based on a 3 hour period, that changes every 6 months. one period ends on October 30th and those surge hours are 3-6pm. Then for the winter months it changes over on Nov. 1st, for the next 6 months, based on the surge range from 6-9am. Both 3 hour windows are when the most energy is consumed in our area.
They use ONE of the three surge hours and mark it the highest we use each day. So for an average month they would have approx. 30 highest surge hour usage for each house.
they then use the very highest of those 30 days, one hour out of the three, as our peak usage hour that billing period. They then multiple that usage by an astounding 12 DOLLARS a kwh. (vs our old 12.4 CENTS)
To off set some of that shock, they lower each of the 23 left over hours at a steady 5.9 CENTS a kwh, or less that half of what we were paying before.
So our entire electric bill is 95 cents a day base charge, plus our one highest surge hour times 12 dollars a kwh, plus all the other energy usage that month at 5.9 cents a kwh.
Last month was our last 3-6pm surge range. We used a 2kwh battery all in one, battery, battery management system, and inverter, to run our bedroom a/c. we run it all 3 hours with lots left over.
We have a 1kwh battery on our inside frig/freezer that uses about 130 watts, but goes all the way up to 600 watts while defrosting. We only caught it doing that once in the month so guessing it doesn't defrost often. The 1 kwh battery works great, even through a defrost cycle. It handled the 3 hour period easily.
Lastly we use a .768 kwh battery on our full size garage freezer that seems to consume 127 watts every time we look at it. It must defrost at some point but we have yet to see it. this battery also handles the 3 hours easily.
We use Ryobi battery 7.5 inch fans that we already had to blow the bedroom a/c out into our main house. And from there we use another Ryobi fan to blow into the kitchen and one into a hallway off the main room to a side of the house we don't really use. We recharge the large batteries at 5.9 cents a kwh in off peak hours, along with the Ryobi 4ah cells that also handle 3 hours with 2 bars left out of 4.
In October the most inside temp change that we noticed was an increase of 2 degrees. Our bill was 86 dollars. As best we can remember our lowest monthly bill was never less than 150 dollars, (over a 15 plus year time frame,) and often would go to 275.
The main pain in the backside using this method is that if we miss one day going from the grid to the batteries THAT is what the utility will use as our monthly high peak hour times the 12 DOLLARS a kwh. however by not missing a day last month our bill said 12 dollars times .4x kwh and was 5 dollars and change for that portion of the bill.
Now for the winter months we have the 85 gallon hot water heater off and the heat pump off from 6-9am, but the freezers will be part of the winter months calculations. Too much hassle and we don't want to leave the big lith-ion battery packs plugged in 24x7, so we put them to sleep for the winter, just draining and charging when storing them according to the manufactures guidelines. Outside temp hit 33 last night but our inside temp only dropped from 68 to 66 degrees as we used the 5.9 cent power right up till 5:57 am to heat the house for the three hours down time.
Anyway, sorry this turned out so long, but it is another usage for the batteries.
Reading reviews on Amazon, one person said you cannot use other brand solar panels due to their proprietary connections.Just thought you might want to check that out first.
