# What Can a 5500 Watt Generator Run? – Unleashing The Potential

*This article is all about answering your queries about “what can a 5500 watt generator run? How many appliances can I run simultaneously and will it run my air conditioner, Sump pumps, and other power-hungry appliances?*

**A 5500-watt generator can run almost every essential of a small household, RV, or job site including microwave, refrigerator/freezer, Air conditioner, Oven, Electric water heater, washing machine, sump pump, well pump, welder, circular saw, electric drills, etc.**

**Understanding the Basics of Generator Wattage**

**Starting/Peak watts: **The maximum wattage a generator can produce for a shorter time to power up the motorized tools/appliances.

The purpose of peak watts is to provide initial inertia to the motor/compressor-based appliances/tools rest of the work will be handled by the running watts.

Starting watts will always be higher compared to running watts.

**Running/Rated Watts: **The maximum wattage a generator can produce to run an appliance/tool in a stable condition. Rated watts will always be lower compared to the starting watts.

**Note: **Starting and running watts (power ratings) can be found in the specification section of the machine.

### How Many Appliances Can I Run Simultaneously With a 5.5KW Machine?

Depends on the power ratings of the appliances you are going to use. Typically a 5.5kw generator can handle 7 – 10 appliances of standard wattages, however, if you want to plug an appliance of 5,000 – 5,200 watts you have access to plug another one of 500 – 1000 watts.

The bottom line is within the range of 0 – 5500 watts you can plug any appliance/tool you want.

**NOTE:** We encourage our readers to keep a margin of 10 – 15% load so that the generator can run comfortably. Don’t ever pull 100% of the load from a generator e.g. a 5.5kw machine should be restricted to 5kw – 5.1kw.

The small margin will not only keep you gen–set away from the overloading but also save your future costs of costly repairs and maintenance.

#### Determining the Powering Needs:

- List down the appliances of your household/RV with their power ratings (starting and running watts). You can find the power ratings from the energy labeling.
- If you found the power rating in amperes make sure to convert them into watts with the help of Ohm’s law.

**Ohm’s Law: W (watts or kilowatts) = Amps (ampere) X V (voltage)**

**E.g. **an appliance/tool is consuming 10 running and 14 starting amps at the voltage of 220V.

**W (watts or kilowatts) = Amps (ampere) X V (voltage)**

**Running = 10 X 220 = 2200 watts**

**Starting = 14 X 220 =3080**

**Note: **You can do the calculation in amps if you are comfortable.

- Sump up the starting and running wattages of the appliances/tools, and make sure to keep them in a separate column.
- Compare it with the generator you want to purchase.

**Practical Example:**

Appliances | Starting Watts | Running Watts |
---|---|---|

Refrigerator | 1200 Watts | 200 Watts |

Deep Freezer | 1300 Watts | 700 Watts |

Washing Machine | 0 Watts | 1200 Watts |

Vacuum Cleaner 12 Amps | 2500 | 1440 |

TOTAL | 5000 Watts | 3540 Watts |

From the above calculation, we got 5000 starting and 3540 running watts, hence a solid 5.5kw generator would be more than enough for the above quotation.

### Will a 5500 Watt Generator Run a Well Pump?

It depends on the power ratings of the well pumps you own, below are some of the well pumps that can be easily operated with a 5500w generator.

### Will a 5500 Watt Generator Run a Heat Pump?

It depends on the size and energy ratings of the heat pump you own, a modern heat Pump of 500 – 5000w will not be a problem for a 5.5kw unit, however, I recommend you to skim the user manual of your heat pump before making a buying decision.

Below are some of the heat pumps that can be easily run with a 5.5kw generator.

Size of heat Pump | Wattages |
---|---|

1.5 ton | 1000 – 1400 watts |

2 ton | 1600 – 1800 watts |

2.5 ton | 2200 – 2600 watts |

### Will a 5500 Watt Generator Run a Welder?

A normal welder of 18 – 20 amps at the voltage of 220V is not a big deal for a 5.5kw machine, however, we recommend always checking the power ratings of the welder from the energy labeling and choosing the generator accordingly.

### Will a 5500w Generator Run My AC?

An RV or window air conditioner of 5,000 – 18,000 BTUs is not a big deal for a 5.5kw machine, however, if you have a central air conditioner with more than 6000 starting watts, you should have to consider a bigger generator of 8 – 10kw.

### Can a 5.5kw Generator Run a Hot Water Heater?

Yes, a standard water heater needs about 4 – 5kw which can be easily handled by a 5.5kw generator.

### Can a 5500-watt generator Run a Furnace?

It depends, a normal household or RV furnace will not be a problem for a 5500w generator, however, if you have a bigger furnace of 10 – 20kw, you should have to consider a bigger generator of 12 – 25kw.

Below are some of the furnaces of different sizes you can run with a 5500w unit.

### Will a 5500 Watt Generator Run a 50 amp RV?

Though a 50 amp RV requires 12500 watts (250V X 50Amp = 12500) of power to run everything, still a 5.5kw generator would be sufficient to run small to medium power appliances/equipment.

Here is the detailed guide about **What Size Generator for 50 Amp RV?**

**Note: **You may need an adopter or plug that can convert 30amp to 50amp.

### How Long Will a 5500-Watt Generator Run on a Tank of Gas?

It depends on the size of the fuel tank, its efficiency, and how much power you are pulling. Typically a 5.5kw generator should provide at **least 8 – 10 hrs. of runtime at 25% load**.

**NOTE:** an inverter generator provides more runtime compared to the normal one.

### How Much Gas Does a 5500 Watt Generator Use per Hour?

Again it depends on how much load you are pulling and how efficient a generator is. Normally a brand-able efficient generator will consume about 0.5 – 1 gallons of fuel/hour depending on the load you are pulling.

## Verdict

Though a 5.5kw generator would be ideal for a normal household, RV, or Job site, still we recommend doing the wattage calculation of your household/RV or job site by following this section of the article.

The wattage calculation will not only save your initial cost but also your future cost of fuel and maintenance.

## FAQs – Frequently Asked Questions

**Will a 5500 Watt Generator Run a House?**

Yes, a small household with standard appliances or tools will not be a problem for a 5.5kw machine, however, if you own some of the power-hungry appliances like central air conditioners, dryers, etc. you may have to consider a bigger unit.

**Will a 5500-watt generator** Run a 3-ton** AC Unit?**

It depends on the type of air conditioner and their SEER. A window/RV air conditioner of **3 – tons** with even **14 SEER** could be smoothly run with a 5.5kw machine, however, if you have a central air conditioner of 3 – tons with 6,000 – 8,000 watts, you may have to consider a bigger one.

**How Many Amps Are 5500 Watts at 220 Volts?**

According to Ohm’s law, a 5,500-watt generator will provide you with about 25amps at the voltage of 220V.

**Will a 5500 Watt Generator Run a Camper?**

It depends on the power requirement, generally, a camper with normal appliances like refrigerators, microwaves, washing machines, and window air conditioners will not be a problem, however, if you have a bunch of power-hungry appliances and you want to operate them at the same time, you should consider a bigger generator of at least 10 – 15kw.
