A large portable generator can be a lifesaver during power outages, providing the essential energy to keep your home lit and appliances working. They’re also a popular choice for powering tools at construction sites, supporting outdoor events, driving food trucks or coffee vans, and even operating heavy-duty industrial machinery. But selecting the right one can be challenging, especially when trying to balance size, power output, noise levels, and budget constraints.

In this article, we’ll compare two models from the popular Hyundai line: the compact yet powerful HY3200SEi and the high-performance Hyundai HY4000SEi designed for professional use. We will examine their power output, fuel efficiency, physical specifications, functionality features, and overall performance. With this comprehensive comparison guide, choosing between these two robust models is now easier.

Performance & Power

Running Power (W): The Hyundai HY3200SEi provides a continuous power output of 3200W compared to the HY4000SEi’s 4000W. A higher running wattage is essential if you plan to run several high-wattage appliances simultaneously. For instance, both these generators can comfortably handle a water heater that needs around 3000 W but only the HY4000SEi could run an additional welder machine requiring 4000 W without faltering.

Starting Power (W): Both generators have the same starting power as their running power.

Engine type: Both models feature OHV engines; however, there’s a slight difference in size: 210cc for the Hyundai HY3200SEi versus 223cc for the Hyundai HY4000SEi. OHV stands for “Overhead Valve” and signifies that an engine is built with its intake and exhaust valves located above the combustion chamber resulting in better fuel efficiency and improved power output. The HY4000SEi’s larger engine indicates that it can generate more power.

Rated Output (kVA): The Hyundai HY3200SEi offers an apparent power of 4kVA, while the HY4000SEi provides a slightly higher 5kVA. This means slightly more current can be generated by the HY4000SEi without resulting in an overload.

Inverter: Both generators use inverter technology to provide clean power ideal for running sensitive electronics like your laptop or smartphone. Plus, they run quieter and save fuel — a win-win situation for everyone!

Fuel & Run Time

Fuel Type: Both models are petrol-fueled machines, a commonly available fuel source in Australia.

Fuel Tank Capacity: The difference in fuel tank capacities is not huge but noteworthy; the Hyundai HY3200SEi has a 7.8L tank, while the HY4000SEi comes with a larger 9L one. A larger tank simply means you can run the generator longer between refills.

Run Time: The HY3200SEi boasts six hours of operation at 50% load; unfortunately, we do not have specific data for the HY4000SEi’s run time but expect it to be around this range as well.

Physical Specs

Dry Weight: At 35kg, the Hyundai HY3200SEi is substantially lighter than its counterpart which weighs about 55kg. This could make the former easier to move around.

Size: The HY3200SEi measures 40cm x 40cm x 56cm, while the HY4000SEi is bigger at 60cm x 45.2cm x 50cm. While neither of these are massive, consider how much storage space you’ve got.

Wheels: Unfortunately, we do not have statistics on whether either product comes with wheels — sorry about this!

Outlets & Parallel Use

AC Outlets: Both the Hyundai HY3200SEi and the Hyundai HY4000SEi feature two AC outlets.

DC Outlets: Each model has one 12V DC outlet, useful for charging small devices like mobile phones.

Parallel Use: We don’t have data on whether parallel use is allowed for either of these generators.

Features & Usability

Features: Both generators come with a Recoil/Electric/Remote start system, making it easier and convenient to get them running. Both also feature a digital display providing relevant operational information in real-time.

The Hyundai HY3200SEi also boasts a digital overload protection and low oil shutdown system, but there is no analogous information on these safety features for the HY4000SEi.

Noise Level

Noise Level: If noise levels are a concern for you, then the Hyundai HY3200SEi might be the better option with a slightly quieter 54-59 dBA range, compared to the 59 dBA of the HY4000SEi. To give you an idea of how loud that is: regular conversation ranges between 60-70 dBA; your refrigerator hums around 55 dBA.

After comparing all essential aspects, both models come out as strong contenders in their own right. The Hyundai HY3200SEi distinguishes itself with a compact design and lower noise level; it could be an ideal choice for domestic uses like caravans or motorhomes. The Hyundai HY4000SEi, on the other hand, offers higher power output and run time capacity, making it suitable for professional tasks or more intensive energy demands like camping trips or construction site operations.

Remember though, choosing between these two depends mainly on what you value most — power output, compact design, noise levels, or extra features.
