When bad weather or other conditions interrupt power service, homeowners can find themselves unable to heat or cool their homes or run necessary appliances and lights.  This situation can be serious if critical applications such as medical devices, telephone, home office computers, sump pumps, or refrigeration are threatened. Emergency backup systems make it possible for homeowners to have continued access to electrical service during power outages. This system is based  on battery-based storage systems.  

The two basic components of battery-based storage systems are an inverter/charger and a set of DC batteries. The inverter/charger converts AC power from the grid to DC to charge the batteries. When power from the grid is lost, the inverter converts the DC battery power to AC for use in the home.

The length of time that a battery-based storage system can provide emergency power to the home depends on its overall capacity and the type and number of appliances connected to the backup system. entertainment and home office electronics, lighting, microwave ovens, and refrigerators. Other appliances, such as electric heaters, electric water heaters, stoves, and air conditioners would place a large demand on the system, and quickly deplete the batteries. Therefore, they are not good candidates for battery-based backup power.
