Tesla power wall I am hearing that for the first time, it stores a lot of charges from the look, I know how it last is determined by the appliances used, so how many appliances can be used at a time and how long does it last if it is lighting only bulbs and mobile devices
For the above it would last a couple of days
the powerwall will discharge 5 kWh maximin at one time, it will run both our air conditioners at the same time.
But the more power load we ask it to provide the quicker the battery level will go down.
If there is sun in your arrive there is absolutely need for electricity then, if it can carry an iron too.
