Exide sine wave 850 va using for last 4 years and no problem till now .
Happy with the inverter and the backup getting
I am getting a backup of 14 to 20hr with average usage with 150AH C10 battery , not exactly same backup every time because of different usage every time.
Best part of this is it has an absolute nice feature of charging the battery at different speeds as slow, med, fast also button for ups mode and non ups mode
Another unique feature is two output slot of 3 pin socket.
