South African portable compressed air and power generation rental company Rand-Air offers a few key tips when considering the rental of a portable power generator.
The first factor to consider is making sure the generator meets the power needs of the user.
In addition to meeting energy requirements, understanding the parameters of the power needs will help identify which genset equipment will best suit the situation, said Lukas Hopley, service manager of Rand-Air.
Hopley said: “Hiring a generator that is undersized when the power requirements of the job are greater than the capacity of the machine, means that the generator will either shut down or trip the circuit breaker.”
“An undersized generator will also slow down the engine by pulling too much horsepower, the voltage and frequency output will become unstable and can result in the damage of the equipment connected to the generator”, Rand-Air said in a company statement.
According to Hopley “an oversized generator is when less than 50% of the rated capacity is used. If the generator is not producing the required horsepower to reach the rated capacity, it can cause it to glaze.”
Rand-Air fleet manager Craig Swart explained: “It is important to size the generator correctly for the application, and to only use a qualified electrician when connecting the generator to the application.”
