The RP12000E 12000 50 generator by the Caterpillar brand is built to power units anywhere and anytime. Ranking thirteenth on our list, it has been receiving generous reviews over the years. Boasting a genuinely simple and easy to use/handle design, it does not take much effort to be moved. 

Users from various walks of life have experienced the 50 amp generator’s extended ability of providing power to various lines. It can sustain stationing electricity to overlapping ports for hours even with low fuel. That is because of its idle control mechanism and a large fuel tank. 

Characteristic among CAT (Caterpillar) constructions is a well-thought and ergonomic design, easy handles, and a practical energy-saving feature planned intelligently by brand engineers. Another notable characteristic of the CAT series models is a built for comfort and sustainability. 

An EPA-compliant model, the RP12000E 12000 yields a perfect balance between heaviness and stability. It is, in fact, plumped so that it reigns heaviest on our list. 

Albeit having been criticized by several users, it manages to maintain an ease of portability (average though) and stability. The generator’s stability, cemented by its rugged steel frame hails it as a grounded generator. 

Engine & Power Performance

This extra-heavy 50 amp generator operates on a grounded command. By being grounded, it fully prepares its system for strong surges, hence its 670cc v-twin OHV engine. As a result, it yields a comfortable, stable and sustained energy flow. 

To further line up its surges, the RP12000E 12000 depends on an idle mode motion  and nine power outlets for continuous surges. This feature works best on high-current power lines like mining bulbs, outdoor posts, and large-scale appliances. 

Due to its large fuel tank, it can run straight for 11+ hours at a 50% load performance. Start it up, and it’ll instantly boost a 15,000 wattage incline; keep it running, and it’ll stabilize at a 12,000 wattage mark. 

Noise Level 

Despite its manufacturers’ claim of a low harmonic distortion feature, the RP12000E 12000 is actually loud. Many think that this is due to shipping inconsistencies as others are quiet.

Overall, its motor performance tends to be stretched up at a range between 75-80 decibels.

13. DeWalt 11700 Running Watts

Best 50 Amp Generators

Main Features:

  • Hydraulic Magnetic Circuit
  • Easy-to-Read Panel
  • Lift Hook Included
  • Covered Outlets
  • Idle Control Mode

The DeWalt PD123MHB008 generator is heavily reviewed and appreciated for its tough, heavy-duty and fast power-traffic performance.

Gearing with 35 AH battery, 120/240v capacity, and a voltage selector switch, this generator ranks as the most luxurious item on our list, hence its “Premium Value” title. 

Why is this generator so expensive? Because, its engine quality is provided for by the Honda GX engine series. This alone, experts believe, make your pocket throw up. 

Honda GX engines have led in the industry for years. And, it continues leading to this day. Engine qualities under this series yield durability, comfort, and high-power performance.

The DeWalt PD123MHB008, for instance, is a CSA, CARB and EPA-complaint generator. Inhibiting one of the strongest surges from any generators in the decade, it normally functions in maximum facilities. Consequently, it also consumes high power energies. 

Another consequence of the DeWalt PD123MHB008’s massive power grid is a tendency to shut down mid-operation. This has been a constant issue with the product. 

Engine & Power Performance

Also one of the heaviest items on our list (second to RP12000E 12000), this premium 50 amp generator costs expensive damages if not properly geared up. It, at least, has the lift hook and GFCI-protected outlets for sustainability. 

Instead of a cc conversion, its Honda OHV engine by an AC frequency of 60 Hz This boosts it with 14,000 starting watts and 11,700 running watts. All these are, of course, supplemented by expensive quality features– digital hour meter, idle control mode, 4 outlets, etc. 

Noise Level 

Since its system has been coated in expensive Honda-quality copper mesh, it’s motor speed is fortunately muted. Staying truthful to its “less than 6% distortion” claim, its noise level doesn’t go beyond 79 decibels.

14. Generac 5802, 10000 Running Watts

50 Amp Generators

Main Features:

  • Covered Outlets
  • 1 1/4″ Steel Tube Cradle for Added Durability
  • 49-State Control Panel

The Generac 5802 generator by the Generac brand is another expensive item that lands last on our list. Distinguishing itself from the rest as an emergency power provider and a uniquely-steeled casing,  the generator ranks as the safest when it comes to power surges.

This advantage comes with a twin. Reviewers criticize it for not being powerful enough to sustain generation. In fact, it is even accused of being mis-categorized in the 50 amp mark. Even with the presence of the counter-claims, the generator actually works on 50 amps. 

Another notable feature of the Generac 5802 is being a temporary power-provider. And, as mentioned earlier, it works best in acting as emergency power.

Even with a large capacity fuel tank, it is still proven to operate for short intervals. Thus, experts suggest cooling it every 2-3 hours. After all, it’s a CARB-compliant engine, so it should not backfire easily. 

Engine & Power Performance

The Generac 5802 is powered by a 220cc OHVI engine that is known for its light and versatile functioning command. Considered to be sufficiently powerful, this engine class fully maximizes pressure using an automotive force to prolong engine life. 

With that, it easily responds to light electric start touch. With a full large capacity steel tank of 4.5 gallons, it can run for up to 13 hours (interrupted) at a 50% load. Its starting mark falls at 5,000 watts, while its running mark is at 4,000 watts. 

Noise Level 

The Generac 5802’s noise level fortunately falls at a 78-80 decibel range. This is further helped by its anti-vibration fold-down handle and never-flat wheels. Nevertheless, full pressure is concentrated in its OHVI engine. Ultimately, in the event of pressure leakage, its PowerBar monitor gives out a beep.

Buying Guides: How to Choose the Right Size 50 Amp Generator?

Either you’re buying a 50 map generator for your RV or homes, you have to buy the right size. And that’s for two reasons. One, to ensure you have enough power for your appliances. And two, to save money. Because buying more than what you need is a waste of money. 

You have to determine how many appliances you need to power. And are you going to power them all at the same time? 

It also helps if you’ll make a list. You need to know the starting watts and the running watts of the generator. Then alternatively, make another list of the starting watts and the running watts of all the appliances that you need to run.

Remember that the starting watts is what you need to “start off” an appliance. And the running watts are what’s needed to maintain them. You can sum the starting watts and the running watts of your appliances. And compare them to that of the generator. Ensure that the generator has enough power to fill in these numbers. 

This will help you decide if you don’t need all the 12000 watts that you can get from a 50 amp generator.

Why You Should Buy 50 Amp Generator

Price-wise, a compact generator might seem a good deal. You might even argue that it’s enough for emergencies.

But it wouldn’t be enough to power all the appliances that you need, in case of a blackout. And you need a generator that has a higher watt vs the total starting and running watts of all your appliances. 

This will ensure that you can run each sufficiently. And if you’re going to run several appliances simultaneously, you need a 50 amp generator.

Even if you’re not going to run all of your appliances at the same time, a portable generator can only supply 25 % percent of your energy needs.

Which Generator Size is Best to Use for Your 50 Amp RV?

Powering the RV is not as easy as you think. Many RV owners, instead of pumping electric current into their RVs, end up doing the opposite. RVs have varied electrical needs and services. Hitting a one-ampere degree should be insufficient if you’re actually aiming for a sustained wattage performance. 

The overarching means for fully understanding the RV’s electric needs is to scrutinize the nitty-gritty of your 50 amp RV system. Only by getting the hang of it can you identify the perfect generator size for your 50 amp RV.

Calculating the Result

To better grasp and measure wattage, you first need to look into the  50 amp RV system. Its system usually comprises a ground wire, two 120v (volt) wires, and neutralizing wires. So when you channel the RV to a generator, you are generating power between 120-240v. Since the 120v is the main surge, it shall be multiplied by two (representing the two surges in the range) that is: 2 x 120v. 

Now, to come up with the total required wattage size, you will have to lay the figures in this formula: 50 (ampere size) x 2 (midranges) x 120v (the main surge), totaling to 12,000 wattage size. 

The highest demand for wattage or generator size, therefore, is 12,000. But that does not mean you’ll have to purchase such a powerful generator because after all, the greatest determinant would be the total kWh needs per appliance. 

If you were keen to observe, our recommended wattage size range– 4,000-8,000- accurately falls within the 12,000 total generator size. 

Here’s a Honda chart for a guided estimation of the generator size. 

FAQs

Can I use a generator even if it’s low on fuel?

That would not be recommended. You either have to shut it down in intervals to allow it to cool. Then, you will have to refuel it. Some models like that of DuroMax and Champion have backup power sources and low-oil auto-shutoff. But, you can’t be fully dependent on these features if you want the generator life to be preserved. 

Which is the best power source– gasoline or propane?

That is entirely dependent on the carburetor. But based on recommendations, the propane power source proves to be mess-free, anti-stick and smooth in terms of delivering power.
