BATTERY BACKUP Backup Power Source - Powered by Alternative Energy - is a complete plug & play automatic power grid connected standby power system or off-grid system, that includes a solar module package that is capable of 1250 running watts, or 1850 surge watts for 120V appliances with 220/Ahrs of battery (included) storage. Includes 1 or 2 120 Watt (or greater) solar PV panels, adjustable roof mount racks, cabling, and all required fusing and controls to make 120-250 watts of peak power production. This backup power system is a complete solution providing power to run your critcal systems in the event of a power outage.  It is constructed using state-of-the-art components and guaranteed to provide power when you need it most. 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. 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. Potential owners need to identify which appliances will be supported by backup power and determine the load needed to accommodate them. The capacity of the system can then be sized to fit the needs identified by the owner.
