Last two years back I purchased this luminous Inverter and ups, two years of using Inverter and Ups recently I am facing the overload problem when ever power cut happens with in 5 to 10 minutes it show Over load and keep on beeping. at first I taught that may be the load is very high so its showing overload, then I remove the output power supply and connected a mobile charger to it, the mobile charger output only 5v 2.5amps but still it shows overload. I called to the service center they told me to buy a new UPS. Very Very bad response.
