Select a rating that is approximately 25% higher than the peak load e.g if the load is about 40 KW, opt for a 50 kW Genset. A well rated generator will operate comfortably at approximately 80% of its full capacity and as well as provide a margin of flexibility if the load increases in the future.
Nonetheless Inverter or Genset outcome is same,(backup AC power supplies) decision mainly to do with costs besides other environmental and operation aspects.. A generator will supply power as long as it keeps running-has fuel.. an inverter will only last as long as the batteries... list is endless
..depending on the size of load, inverters have huge initial cost but the long-term cost of ownership would be less etc.. etc
for the genset keep in mind that you need to consider what happens to the computers when power is changing from
KPLC to Genset and vice versa
Some correction.. Inverter running cost is nearer to zero but not Not Zero

have you considered a power backup system ( inverter charger) the initial cost may be high but running cost is zero
