There are larger generators that can produce 10,000 W of power, and there are also smaller generators that produce 5000 W or less power output. But, the 7500-watt generator hits the middle spots. Suppose you want to run some larger household appliances, such as space heaters, air conditioners, freezers, etc., with the portable generator. In that case, the 7500W generator can provide power to charge those devices — though not all at the same time.
If you are looking to purchase a 7500W generator, it's essential to understand the different types of generators available in the market. For example, propane or gas generators use fossil fuels to work and emit toxic fumes when charging appliances. On the other hand, inverter generators and solar generators use clean energy and do not emit any harmful gases. Let's explain them briefly :
7500-Watt Portable Generator : As their name suggests, the 7500W portable generator has a wattage capacity of 7500 and generally features wheels or handles for easy movement.
7500-Watt Inverter Generator : Inverter generators are best known for their quiet and fuel-efficient nature. They are much preferred for charging sensitive electronics like mobile phones, laptops, TVs, and even RVs.
7500-Watt Solar Generator : Solar generators are reliable and emission-free alternatives to gas and propane generators. They often come with solar panels to generate electricity and charge the portable power station, which can then power household, RV, or outdoor appliances.
Before you choose the generator, it is essential to understand different terms related to wattage. Here, we will explain them :
Starting Watts : As the name suggests, the starting wattage is the wattage required by any indoor or outdoor appliance to start. Many appliances need more wattage to start up and less to keep running.
Running Watts : Sometimes referred to as rated wattage, it is the amount of electricity required to keep the appliance running for hours. It is typically the multiplication of amps and volts of the specific appliance.
Surge Watts : It's the highest amount of wattage or power a generator can produce while charging the appliances. Generally, the surge peak output of the Jackery Explorer Portable Power Stations is double their rated wattage.
Watt-Hour : It is equal to one watt of power delivered in one hour. The watt-hour also defines the battery capacity of the solar generator or portable power station, indicating how much energy it can supply. A generator with a higher battery capacity ensures you can run appliances for long hours.
What Size Generator Do I Need?
The size of the solar generator needed to power a household, work site, RV, or any outdoor adventure will depend on the wattage of the appliances you are charging simultaneously. A generator that can provide anywhere between 5000 - 8000 W would be enough to charge a typical household. With a 7500-watt generator, you can expect to charge almost all the essential household appliances, such as air conditioners, refrigerators, sump pumps, light bulbs, and TVs.
If you are still wondering "what size generator do I need," you need to follow a few steps mentioned below :
Step 1 : List the Appliances
The first step is to list all the appliances that you plan to use "simultaneously" in your household, RV, or while camping. You need to take into account both the running and starting wattage of the chosen appliances.
For example, we assume you want to charge the below-mentioned appliances at the same time :
- Refrigerator : 600 W running / 1200 W starting
- CPAP Machine : 30 W running
- Coffee Maker : 1000 W running
- Electric Water Heater : 1300 W running
- Window Air Conditioner : 1800 W running / 2700 W starting
If you cannot find the wattage consumption on the appliance itself or in the user manual, consider multiplying amps by volts to get watts.
Step 2 : Add Appliance Wattage
Now, add the running wattage of all the appliances you chose in the previous step. In this case, the total running wattage is 4730 W.
Step 3 : Calculate Total Generator Watts
Find the electrical appliance with the highest starting wattage in the list and add the number to the total running watts. Here, the window air conditioner has the highest starting wattage of 2700 W. The total running and starting watts are equal to 7430 W.
The obtained number (7430 W) is the minimum starting wattage of the generator you need.
Here's the diagram that reveals the calculation and how to determine what size generator is required for the needs.
What Can a 7500 Watt Generator Run?
A 7500 W generator can run most small and large appliances, including large window ACs, refrigerators, deep freezers, water heaters, sump pumps, etc. The best method to understand what can a 7500-watt generator run is by checking the running and starting watts of the appliance. In the case of a 7500W generator, remember that the running wattage is 7500 watts, and it will have around 9000-9500 W of surge power capability.
Will a 7500-watt Generator Run a House?
Yes, a 7500W solar generator is a decent-sized generator for most household appliances, including space heaters, ACs, refrigerators, TVs, mobile phones, coolers, and sump pumps. However, it is always a good idea to balance what appliances you are planning to run at the same time with your 7500-watt generator for the house. For example, running a dishwasher, washing laundry, and keeping the AC on all at the same time can put a strain on a 7500-watt generator.

Work Site
Large 7500W generators are suitable for work site appliances that demand high wattage, such as bench grinders, table saws, miter saws, pressure washers, and electric drills. Remember, some power tools and motor-driven equipment used at work sites are measured by horsepower. It's always a wise idea to double-check the starting wattage required for motor-driven equipment, as it may need nearly two to four times as much power to start as it does to run.

How Many Amps Does a 7500-Watt Generator Put Out?
A 7,500-watt solar generator will produce nearly 31.25 amps at 120 volts or 40 amps at 240 volts. This is because amps are equal to wattage divided by voltage.
Here is the mathematical representation of the formula :
Amps (I) = Watts (W) ÷ Volts (V)
When the wattage is 7500 W and volts are 120 V, the amps are :
I = 7500 W ÷ 120 V = 31.25 A.
Similarly, if the volts are 240 V, the amps will be :
I = 7500 W ÷ 240 V = 40 A.
Let's take another example to understand :
Jackery Explorer 2000 Plus Portable Power Station has a LiFePO4 battery capacity of 2042.8 Wh and is typically operated at 44.8 V DC. The amp-hour can be calculated using the below formula :
Amp-hour (Ah) = Watt-hour (Wh) ÷ Volts (V) = 2042.8 Wh ÷ 44.8 V DC = 45.6 Ah.
This means that the Jackery Explorer 2000 Plus Portable Power Station will produce nearly 45.6 amp-hours of power.
What is the Quietest 7500 Watt Generator?
Compared to gas or propane generators, solar generators are quiet as they do not have any moving parts. For this reason, solar generators are preferred for charging indoor appliances at night. The Jackery Explorer 2000 Plus Portable Power Station features a Quiet Charging Mode that ensures the emitted noise level is less than 30 dB.
You can quickly activate the feature using the Jackery mobile app and freely run the generator to charge appliances overnight. Additionally, the Jackery Explorer 2000 Plus Portable Power Station has a capacity of 2042.8 Wh and can be expanded up to 24 kWh, making it ideal for running appliances for a long time.
How Long Does a 7500-Watt Generator Last?
The running time of a 7500 W generator will depend on how many appliances you are charging at the same time. For example, if you are charging appliances that consume high wattage, the running time of the generator will be lower.
Here's an example to understand better :
Suppose you are charging a refrigerator (600 W), electric stove (800 W), TV (150 W), and LED lights (30 W) at the same time. If you are charging all these appliances with the Jackery Solar Generator 2000 Plus (6 kWh), the working hours can be calculated using the below formula :
Working Hours = Battery Capacity in Wh × 0.85 / Wattage Consumption of All the Appliances = 6128.4 Wh × 0.85 / 1580 W = 3.2 H.
We are multiplying the solar generator's battery capacity by 0.85 instead of 100 because charging the appliances will cause some power loss.
Conclusion
If you are planning to buy a 7500-watt generator, we recommend you understand the power consumption of the appliances you want to charge simultaneously. The choice of the best generator for residential, camping, worksite, and RV appliances will differ depending on what you want to run.
If you are still unsure which solar generator will fit your needs, you may consider the expandable and versatile Jackery Solar Generator 2000 Plus, which can be expanded from 2 kWh to 24 kWh. If you wish to charge essential worksite appliances for some time, the Jackery Solar Generator 2000 Plus (6 kWh) might be a good choice.
On the other hand, if your goal is to go off-grid and charge most household appliances with solar energy, you might find the Jackery Solar Generator 2000 Plus (24 kWh) more reliable.
