Interesting. My house is typical 1960's build in the U.S. (Colorado urban) and I've done nothing really to make it more efficient other than mostly converting to LED Lighting. I use a max of about 20Kwh per day.... No AC - Swamp cooler in the summer, Natural Gas Furnace and Hot Water (I'd love to get rid of Natural Gas but that would also increase my Electrical usage).As I have said far too many times, LFP has a designed Working Voltage of 3.000-3.400 which is where the deliverable AH are supposed to come from. Generally the "safe zone" is from 2.850 up to 3.425 with A cells. Once outside of the working range, running occurs. I set my LVD to 2.700 because if there is a heavy load when below 2.9 it can drop low "momentarily" so I account for a buffer.
My home uses on average 4kWh per day. sometimes a bit more or little less but not more that 1/2kWh. Everyone freaks at that but there is good reasons for it. I designed & built this house for High Efficiency, my walls are 9" thick, Roof is 12" thick. All Insulation is High Density Foam, I have a Cool Roof system tied into a Rainscreen siding system that provides not only a thermal break but passive cooling in summer and a heat buffer in winter. I tossed away my AC system as the house never gets above 27C/80F even when it is 37C/100F outside. In winter when it is -30C/-22F the house remains at 25C/77F inside and the heating system only runs for 4 hours within a 24 hour period. Yes it is all monitored & tracked.
My final version of Solar (now in progress) will be completed with 1470AH/37.6kWh.
