Having recently upgraded my system, I can now actually see more accurately what power we are using.
Background load seems to be about 400W daytime, dropping to about 250W overnight. I wonder how this compares to other peoples usage?
It's a fairly modern, purpose built house - 4 beds, 3 full time occupants, most normal conveniences etc. 2 large freezers + fridge/freezer.
I haven't been particularly careful about reducing standby loads, although there may be scope to do so.

Re: Off Grid base load?
The figs i have always seen suggest the typical house has a standby load of 200-300W and my own is 250W. This accounts for 50% of the average leccy bill! before water and EV.
Re: Off Grid base load?
Ordinary 5-bed house with 2 adults, 2 children, and a dog. My overnight baseload is around 400W this rises to around 500W in the daytime. We have a truly vast number devices that draw teeny tiny amounts of electricity. There is no "quick win", although I did find an old TV booster in the loft that'd been drawing 20W, 24/7/365 for the 10 years since we bought the house, even though we'd never once watched terrestrial TV...

When the (brand new) fridge freezer's compressor isn't running my base load is 45-50W.*
That's just one (LED) light on, Wifi router, CH controller + Rasberry Pi and standby on TV+box.
*the old fridge freezer used 20W even when the compressor wasn't running!

Re: Off Grid base load?
Fridges and or freezers are sneaky vampires when old. We run at about 130W average base load. Can dip down to 90W but not for long.Stig wrote: ↑Thu Sep 23, 2021 2:16 pm <Smug mode>
