Customer Questions & Answers

Question:
What is the noise level of the GENMAX DIY Open Frame Dual Fuel Inverter Generator?

With its innovative design, you can enjoy the benefits of a generator without disturbing your family, neighbors, or the natural environment. -
Question:
What is dual fuel capability and how does it work?
Answer: The dual fuel capability refers to the generator's ability to run on both gasoline and propane. This maximizes convenience and flexibility, allowing you to choose the fuel option that best suits your needs. For example, using propane can often lead to cleaner emissions, while gasoline might be more readily available in certain locations.

Question:
What is the CO Alert feature, and why is it important?
Answer: The CO Alert feature is a crucial safety mechanism that detects carbon monoxide levels in the environment and automatically shuts down the generator when unsafe levels are detected. This is important because carbon monoxide is a colorless, odorless gas that can pose serious health risks. With this feature, users can operate their generators with peace of mind, ensuring the safety of themselves and their loved ones. -
Question:
How does the parallel and series capability work?
Answer: The parallel and series capabilities allow you to connect two GENMAX generators to double your output power.

To connect, you’ll need the appropriate parallel kit, making this a practical solution for users needing more power without buying a larger generator. -
Question:

Answer: The GENMAX inverter generator has compact dimensions, typically measuring around 23 x 18 x 17 inches, and weighs approximately 100 pounds.
