Predator 3500 Generator – Things to Consider
The Predator 3500 watt super quiet inverter generator is perfect for outdoor recreational use, RV use, camping, and even tailgating.
It also produces enough power for home use and emergencies. Specs and features play a significant role in your generator choice.
The other factor to consider is watts. Everything you use that is electrical has a specific number of watts that it runs.
You determine your wattage by multiplying your volts and amps. You will need to do the math to see how much your volts and amps equates to in watts.
You want to focus on running the generator at its running Watts and generally want to avoid pushing it to its peak watts for prolonged periods.
Running it at peak watts for an extended time can put a strain on the inner workings of the unit. This type of strain can cause the unit to malfunction or stop working altogether.
Another factor to keep in mind is, in most cases, improper use will also void the warranty.
The Predator 3500 is an inverter generator. This feature makes it quieter and more fuel-efficient, but what exactly is an inverter also it comes with an electric start.
What Is an Inverter?
An inverter takes power and changes or “inverts” it into cleaner energy that is more usable for your sensitive electronics.
Inverter technology is newer to generators. The inverter itself is a unit made of specialized electronic circuitry and magnets.
Green Gear Global states that the technology behind inverters puts out an “AC current like most conventional generators, but the current is then connected to DC voltage.
This energy is then “inverted” into AC voltage power again, but this version is clean and consistent energy.
Regular AC power is block waves. However, this new inverted power is composed of sine waves. Total harmonic distortion is the measurement for these waves. Total harmonic distortion allows power systems to have:
- Lower peak currents
- Less electronic heating
- Low electromagnetic emissions
- Low probability of core loss in motors
This new current of power produced by this process is a constant flow of volts to your appliances, which protects your more sensitive electronics such as laptops and televisions.
The THD plays a vital role in allowing you to use inverter generators for high-tech devices.
This constant flow of energy is also what allows the inverter generators to be more fuel-efficient. The engine speed adjusts to the power flow that is needed instead of running at a constant RPM as traditional generators do.
As far as quality goes, the inverter generator’s power is similar in quality to the electricity that you will generally get from your electric company.
Why Is an Inverter So Quiet?
By design, inverter generators are automatically quieter than conventional generators. Their engines are quieter and have specialized mufflers and technology for sound dampening.
Because of its microprocessors and electronics, it will automatically lower engine speed when it is running a lighter load of power, which leads to the reduction of noise.
Conventional generators are generally noisier because their power output is continuously fluctuating.
Many inverter generators can run at a decibel level that is similar to a group of people conversing, whereas a conventional generator is similar to a chainsaw.
Since the noise level of generators is a sticking point for many buyers, manufacturers spend extra time and energy on ensuring that the inverter generators have everything they need to be as quiet as possible since this is one of its primary selling points.
Is an Inverter Generator Powerful?
Because they are smaller and portable, the amount of power that can be produced by an inverter generator does not pass around 4000 watts.
While shopping, you will most commonly see them running anywhere from 1000 watts up to that 4000 watts.
While inverter generators may not be powerful enough for heavy-duty use, it is perfect for outdoor activities like Rving, camping, hunting, and other recreational activities.
The bonus is it will allow you to enjoy nature still and have a conversation without the noise pollution.
Why Is an Inverter Generator More Expensive?
Just like anything we buy, having more features comes with a higher price tag. When it comes to pricing, you are paying for these benefits:
- Fuel efficiency.
- A constant flow of power
- Quiet operation
- Ease of use
These features factor into the price of the unit on top of the usual factors such as watts, engine size, and fuel tank capacity. Ease of use and easy product care also comes along with an inverter generator.
Predator 3500 Generator Housekeeping
Since Predator 3500 is an inverter model, it is easy to maintain. It comes with a manual that lays out easy care instructions and a maintenance schedule.
The unit also has an illustrated quick start guide to make running the generator as user-friendly as possible.
It is important to remember to perform the first service on time within the conditioning period and to make sure the maintenance happens on schedule after that.
This will keep your Predator 3500 running in tip-top shape and will keep your warranty intact.
Problems and Common Issues
All generators come with their issues and we’ve identified some of the most common below.
1. How do I Start my Predator?
To start your generator, use the clearly marked electronic start that is built into the machine, which is displayed on the control panel. It doesn’t take a lot of effort to get your generator started. Once you rotate the throttle knob into starting position, then flip it back once it runs.
2. Why is my Predator 3500 surging?
The most common reason for your predator surging is because the fuel supply has been cut off due to the float in the carb being stuck. To solve this, tap on the side of the float bowl and you should quickly fix this.
Another issue we come across can be related to the fuel bowl needing to be flushed or debris built up in the fuel line. To fix this, disconnect your fuel line and clear out all of the debris.
3. Why does my Predator keep dying?
If you’re experiencing your generator dying you will need to ensure you don’t have an issue with the carb being clogged or not getting sufficient amounts of fuel. This will prevent the motor from running and result in the machine dying.
It usually takes a period of time for this to clog up and shouldn’t be something that happens on initial use. It is recommended that you regularly use a carb cleaner for your engine to mitigate this issue.
4. Why is my Predator leaking gas?
The reason your machine will leak gas is because the float bowl is stuck and can’t move to switch off your gas feed. Make sure to regularly clean out the float bowl and carb. You should correctly drain the float inlet needle or get a professional to service your generator.
Now that we have explained more about the technology behind an inverter generator, and how it differs from conventional generators, you can see how Predator 3500 is the best of both worlds.
It is quiet, compact, and portable. The 3500 peak watts give you plenty of power to run your essentials, whether you are enjoying your favorite outdoor activity or using it to help power tools for your business.
If you are using the Predator for emergency backup, your neighbors will enjoy its quiet functionality as much as you will.
Most importantly, its power is clean and will not harm your electronics, especially those with microprocessors, which these days can be a lot.
It has a decent cost to features ratio and its fuel efficiency will allow you to recoup some of the cost associated with buying an inverter generator.
Its overall versatility and excellent consumer ratings make the Predator 3500 a reliable purchase for taking care of your generator needs.
