I googled a little and found most people recommend Exide IT500 battery not sure about the inverter brand though

Update:
Local dealer of Inverters and batteries suggested Luminous 1050 Sine wave Inverter around 6k
Battery Exide Inva Tubular was not available , InvaRed InvaMaster and Luminous Tubular available totalling around 18k, 19k and 16k all around 100-115AH with the above inverter.
