Want to purcahse inverter then consider my this review for microtek inverter and its tubular battery. I purchased it 2 year back, 1 year its working fine but after that its backup is down to 50% we checked it out with its technician but no increment in its performance.
We are caring its by checking it battery water on every 2-3 months if required we fill it. Its battery performance is also low. Before we used exide battery its much better than it.
Customer service is ok of it.
But if you want to it then from my side a big No to it.
Go for Su-kam its much better from it
