Good luck selling your wife / flatmate / employee on these tips without a nice visual aid. It gets much harder when there are multiple power users. Great list

Good luck selling your wife / flatmate / employee on these tips without a nice visual aid. It gets much harder when there are multiple power users.
Great list by the way. Our offgrid house uses the same amount of power per day as two towel rails by applying this sort of approach. The main power hogs are pumping fresh water and sewerage.
- jacquesm 17y agoI wasn't aware the 'towel rail' was a new measure of power consumption, would that be the bath-towel rail or the toilet one ? Seriously though, how many KWh do you go through in a day ? We managed to get by on 1600 W of solar panels in Northern Canada, which in some weeks was touch and go on battery depletion (you really don't want to get below 70% or so). That's what kept us going in the dark of winter: http://pics.ww.com/v/jacques/renewables/batteries/IM000398.JPG.html http://pics.ww.com/v/jacques/renewables/batteries/IM000398.J...
- gridspy 17y agoYeah, the towel rail is for the people who don't understand kWh. That is 3.5KWH per day, powered using a 640W solar array and a petrol generator when there are several days of particularly bad weather. The battery bank stores 1200AH at 24V, and like you we try to keep it at 70% charge or above. Gridspy was born out of monitoring power usage at the house both while there and while back in Auckland (90km away).
