Generator sets, as an alternate source of power supply, come in their different sizes — which grows proportionally and in accordance with their output voltage and performance.
Depending on where you intend using a generator (home, office, factory etc), or the appliances, equipment, and machines you intend to use it to power (refrigerators, deep freezers, heavy machinery, air conditioning units etc.), the type and size of the generator set to purchase will differ.
There are smaller generator 2.5KVA and 3.5KVA generator that are available to cater for your basic home appliances (like television sets, electric bulbs, fan etc) that requires electricity. There are also generators (5KVA and 10KVA) with relatively larger output that can supply more power to your office and home.
