You can not obtain a very small and light generator because a 12kw generator has a large engine and many parts. A decent 12000-watt generator should weigh between 200 and 300 pounds and be portable enough to be carried about with ease.
Essentials and outlets:
Essentials and Outlets: Depending on the demands of the user, you must choose a machine with all the necessary outlets.
Two 120V, 20amp outlets, one 120V, 30amp RV-ready outlet, one 120/240, 30amp outlet, one 120/240, 50amp outlet, a 12v DC port for charging batteries, several reset breakers, and indicator lights are all essential components of a solid 12000-watt generator set.
Safety features:
Safety Features: The unit you have chosen should have low oil, overload, and voltage fluctuation precautions that have been approved by the EPA and CARB. Additionally, if you want to use any voltage-sensitive appliances, you must be mindful of the THD levels.
Based on our experience with high-wattage generators, it is rare to find a generator with THD levels below 5%; instead, you will need to choose one with THD levels below 10% or 15%, which is still acceptable given that contemporary tools and appliances are capable of handling such high THD levels.
Maintenance and usage:
Usage and Maintenance: Your device should be simple to operate and maintain. I usually like remote-start or electric start 12000-watt generators over manual ones. Additionally, maintaining it should not be too difficult.
Price, Warranty, and customer support:
Price, Warranty, and Customer Support: Your machine’s price tag should be reasonable; a decent 12kw device should cost between $1000 and $3000. Additionally, you must be concerned about customer service and warranties.
For us, a longer warranty indicates that the producers are confident in the product’s longevity and durability.
