An Australian community for everything from your backyard to beyond the black stump.

Topics may include Aussie plants and animals, environmental, farming, energy, and climate news and stories (mostly Aus specific), etc. New related communities will be split off when required, think like subcommunities that exist on that other platform.

Trigger Warning: Community contains mostly bad environmental news (not by choice!). Community may also feature stories about animal agriculture and/or meat. Until tagging is available, please be aware and click accordingly.

Depends.

If you have, say, a 75kWh battery, that's 3-4 days of average summer usage in a large house.

So if you use it to shave off peak usage costs from 4 to 9 pm and then you top it up off peak again from 1 am to 6 am, you cycle through about 10-20 percent of it's total capacity. If you kept doing this in the mid-range of your battery , like 55-75 percent, it would have a negligible effect on battery life.

Also consider a car probably sucks a lot more current from the cells than a house (while accelerating). Batteries are much happier about low current draw so it's probably much milder wear than driving the car for the same amount of energy
