Buying the right generator can seem like a formidable task. Actually, in just a few easy steps, you can effectively determine which generator is right for you.
-
Identify the tools and appliances you wish to operate with your generator.
-
Determine the required wattage for each.
-
Total the required wattage of items that will be run simultaneously.
-
Choose the generator that meets or exceeds this total wattage requirement.
IMPORTANT CONSIDERATIONS:
MOTOR STARTING is another consideration when buying a generator. Keep in mind that, depending on the efficiency of the motor, it may require up to 2 times the running watts to start or 7 times for air compressors, pumps, and air conditioners.
