Howdy gusy My inverter is out of guarantee there was some issue, I called to client mind and enlisted. the grumbling and plainly told at whatever point some person visits, he will reach without illuminating. They will check the inverter and on the off chance that it is in guarantee then they will amend it promptly with no part change however in the event that it is out guarantee the designer will tell any of the vital part has gone and they will tell great measure of that and they will convey your old part so you can't check it from outside, is there any issue or not? When you inquire as to why are you taking old part when you are charging sum for new part? why are you taking old one? at that point they will say, sir it is organization arrangement. Why we will give our old Part when it is not working? So terrible experience. Try not to utilize this item
