I bought an Inverter from Kongu Engineers three years back for my house use. The inverter is working fine and it gives very good backup during powercut. This inverter requires minimum maintenance. Their service support is excellent. I have recommended the product to many of my friends and every one is happy about this product.

My office is protected by a Ryben UPS. It has saved my equipment from surges, spikes and blackouts on numerous occasions. The best UPS to me is Ryben.

The UPS system has proven to be an excellent system and choice for Kalgan. We have experienced zero downtime or disruption to our business when the local power fails, which happens many times a day. We are very proud and happy with our solution and recommend Kongu Engineers for any companies.

We have purchased several Invertor's from Kongu Engineers for most of our stores & it is works without any trouble for last couple of years. The most impressive part is that, they do same level of service care even for products that are not supplied by them. They are too good for customer service.
