When buying generators the major question to consider is how much power do need. I most cases visiting a generator manufacturers website can solve the issue since some of them have calculators which helps you with estimates of the amount of power you need. The 5 KVA generator is easily recommended for standard homes. The 5 KVA can power most appliances in the home at the same time but I will not include AC since the power will not be enough. power you need, you'll want to consider the criteria below.
Most people do not understand that a stand-by generator refers to generators with automatic process which kicks in and starts and starts the generator when there is power outage within seconds. That term "Stand-by generator" is misused often. So when buying a generator here in Ghana, consider this. If it is not a "Stand-by generator" you will have to manually start it when there is power outage.
A silent or sound-proof generator is is reasonably quiet and does not disturb the your neighbors. It is the best to buy if your budget can afford it. Technology has evolved and many manufacturers like Honda, Hyundai, Perkins, Cummins, bobo, TEC, Elemax are building generators that are relatively silent. Always check the dba description on the generator. Sound levels are measure in decibels.
Finally, you need to consider if you need a diesel or petrol generators. Price of fuel might be the most important consideration here. In some cases the prices of diesels are higher but you will need to consider the fuel consumption of the generator per hour.
