[QUOTE="Praks, post: 1805065, member: 14590"] @[USER=12693]adder[/USER] Had pathetic exp with APC ( I know they are good) I requested for sales person to come home & explain me various types of models they have & which one will be good for home., Person said there is no margin in APC & he will not come all the way to home just to explain. Just order the model & they will come to fit. Duh.. Anyways, coming back to Sukam issue. Had discussion with their engineer & they promptly came home. they replaced a big capacitor on right side of inverter & zooom all noise stopped. Conclusion: They say out of 1000 Sukam inverters 1 or 2 has this problem. Due to bad quality capacitor, output voltage is not pure sine wave so fans make noise. All is well now. Impressed by prompt service of Sukam +1 for that. No charges at all (in warranty) Thank you everyone for your time on guiding this & hope my feedback is helpful in future if someone refers this thread. [/QUOTE]
