BACKUP POWER SYSTEMS
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. While fireplaces can provide some heat and flashlights or lanterns can
provide light, many appliances will remain unusable until power from the grid is
restored. 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 currently available on the market make
it possible for homeowners to have continued access to electrical service during
power outages. These systems are typically based either on fossil-fuel-powered
generators or on battery-based storage systems. While the goal of both
approaches is the same - to produce backup power - they each have advantages
and disadvantages. For emergency backup power during typical power outages,
battery-based systems represent a fairly simple and silent alternative.
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. Battery-based systems are not
designed to provide power over an extended length of time. For example,
product literature by a producer of backup power systems, indicates that a
typically configured 2000-4000 watt system can provide typical priority household
appliance loads for 2 to 12 hours. However, power conservation can extend
operating time considerably longer. Additionally, fossil fuel-fired generators or
photovoltaic equipment can be integrated into some systems to replenish or
supplement the batteries when power is not available from the grid, or to help the
batteries support the home's load.
These systems are well suited to maintaining service to furnaces, entertainment
and home office electronics, lighting, microwave ovens, and refrigerators.
