Backup systems are required for Off-Grid does not. By definition you do canrrrt you create the Power Company's control. Your stored energy is the initial line of backup. That is designed for getting a 24-hour fill. What do you do later? If your solar, wind and magnetic power sources no longer work you'll need a gas or diesel generator. Because may energy storage, you only need to recharge the batteries which will take a substantially smaller motor. A 400-watt gas generator will cost $102 and maybe a 3,750-watt gas generator price you $500. Overlook these generators have a fuel and maintenance cost as well as provide free energy.
Now, regarding the latter case, the luxury cars [petrol/30kw diesel Generator], people can easily still buy them, but they cant be driven in cities.for practical reasons which you and also me realise. They can be kept purely for that driving comfort and experience with long shots off the tee. This is for the driving supporters.
