Most home power systems in Asia, India are now wired for 220-240 VAC, and an inverter is installed to feed these circuits. An inverter not only lets you use standard appliances and tools but conventional wiring as well. In larger remote residences, particularly those using auxiliary generators, inverters can reduce the costs of power generation by up to 90%. Most inverters include a stand-by battery charger, so that when the generator is on, the batteries are automatically recharged. Once the generator is turned off, the inverter system powers the same AC circuits. Not only do you have quiet power available 24 hours a day, but in most cases the fuel savings alone can pay for the complete cost of the inverter system in less than a year!
