Don’t buy numeric inverters, as the inverter itself is very bad and about the customer service is worst. I bought numeric ups 15 days back, and getting some continuous buzzing sound. I reported to them and they have sent a technician, who dont know about buzzing indication. one week gone, no representative turned up to rectify the problem.
I am having another one Amaron its working without any issues from last 2 years.
Please don’t this product.
