When I was planning to buy a new inverter I consulted my friends and colleuges some of them asked me to go for the local brands as they are cheap but as I had already suffered the consequences with my old inverter so I decided to go for a branded one, in the branded segment there were many option but I opted for sukam as my brother was using it and was satisfied with the performance
I bought Sukams Pure sine wave product from last 1 year now and have not faced any kind of problem till date, I had also bought a Sukam SMF battery(One which does not require water topping).
There are frequent & long power cuts in our area, sukam inverter charges the battery faster hence during frequent power cuts we get uninterrupted power supply
there is no problem with the backup and I dont know why but my fan does not make that irritating buzzing sound that it use to make earlier, with my old inverter. The display on the inverter is very user-friendly and is easy to operate, it gives clear indications of Overload and stuff so it is always easy to manage it.
In short thumbs up for the product
