Inverters are electric power generators.They simply convert (invert) battery power (DC) to AC power (that we use for our household appliances). When the utility company (NEPA) or (PHCN) fails, the inverter takes over, delivering noiseless power and it does not require fuel or deidel to operate. And when the utility (NEPA) or (PHCN) restores power, the inverter is equipped with a fast automatic bat
tery charging system that quickly recharges your batteries. And so the system is self sustaining. The inverter is also equipped with an automatic transfere switch that automatically transferes you to the utility whenever power is restored. It even has a standby mode (UPS mode) that prevents you from experiencing power failure by comming ON the instant (in micro seconds) the utility fails. When you activate standby mode, the inverter powers ON the instant the utility fails such that your lights, T.V, decoder, airconditioner, fridge, etc do not even blink, rather they continue working as if there was no power failure.
