The system uses eight deep cycle batteries to store energy while the grid is operational, and delivers electricity from the batteries to the telecenter equipment when grid power is out.

The inverter plays a central role in this solution by converting AC from the grid to DC to charge the batteries; by regulating the battery charging; and by converting DC from the battery back into AC to power the telecenter computers when the grid power is out.

The total cost of three backup power systems to equip three telecenters was approximately US$16,000.
