Power Backup

Backup Systems There will be times when neither the wind generator nor the Solar panels can produce electricity such as at night or when the wind is not blowing. A good alternative energy system would be able to provide power from a backup generator that can be used to give electricity directly or through a battery storage bank. When the batteries run low an automatic switching system will start the engine-generator and can be run at full power until the batteries are charged. Battery banks are typically sized for one to three days of operation to supply electrical needs during noncharging periods.
