I have uses luminous Inverter. I think Luminous 875 VA sine wave inverter is the best in this power. reasonable price. good looking and fantastic sport for battery.
I agree that It is pure sine wave inverter based on IGBT based PWM technology. The PWM(Pulse Width Modulation technology) is an updated technology that provides output that matches to grid supply. This feature assures safety of appliance against voltage fluctuation or overload.
