This luminous inverter is very helpful. A few months ago when we dont have any backup source we decided to buy it after that we never reaize that light has ever cut or whater happns to light. It very good in backup and giving power. We run almost 10 to 15 LED’s and 4-5 fans and it never shows any fault or anything so its just very useful and helpful for those who are buzy in life and who needs light every tym so my advice that its very safe to buy it and it is not much expensive. So its good it aowsome its usefull. At last it is very good.????
