    The hybrid power plant is a complete electrical power supply system that can be easily configured to meet a broad range of remote power needs. There are three basic elements to the system - the power source, the battery , and the power management center.

  8. Backup battery - Wikipedia

    en.wikipedia.org/wiki/Backup_battery

    The backup battery usually has a lifespan of 3-10 years depending on the make and model, and so if the battery runs flat, there is only one main source of power to the whole system which is the mains power. Should this fail as well (for example, a power cut), it usually triggers a third backup battery located in the bellboxes on the outside of ...
