Overview

Generator sets, also known as gensets, are essential for providing backup power in case of electrical outages or for use in remote locations without access to the power grid. They consist of an engine and an alternator, which together generate electricity. Gensets come in various sizes and capacities, making them suitable for residential, commercial, and industrial applications.

FAQ

What factors should I consider when purchasing a generator set?

Consider the power output you need, fuel type (diesel, gas, or propane), and whether you need a portable or stationary unit. Additionally, check the reliability of the brand and availability of spare parts.

How can I ensure my generator set is shipped safely?

Choose a reputable shipping company that specializes in heavy machinery. Ensure the genset is properly secured and protected from the elements during transit.

What is the maintenance schedule for a generator set?

Regular maintenance includes checking oil levels, fuel system, and battery. Additionally, perform periodic inspections of the air filter, cooling system, and electrical connections. Refer to the manufacturer’s manual for specific maintenance intervals.
