What is a 1000 Watt Generator?

A 1000 watt generator is a portable power source that can generate up to 1000 watts of electricity. These generators come in three main types: portable, inverter, and solar models.

Portable generators are fueled by gasoline or propane and are designed for outdoor use. They are typically more powerful than inverter generators but also louder and produce emissions.

Inverter generators are also fuel-powered but use advanced electronics to produce cleaner, more stable power. They are quieter and more fuel-efficient than traditional portable generators.

Solar generators, like Growatt's models, are powered by solar panels and rechargeable lithium-ion batteries. They are completely emission-free, silent, and can be recharged from the sun or a regular wall outlet. Solar generators are the most environmentally-friendly and versatile option for portable power needs.

How to Calculate Generator Size Needed?

To determine the appropriate generator size for your needs, you need to consider both the running wattage and the starting wattage of the appliances you plan to power. The running wattage is the amount of power required to keep an appliance operating continuously, while the starting wattage is the surge of power needed to initially start the appliance.

When calculating the required generator size, you should add up the running wattages of all the appliances you intend to run simultaneously. This total running wattage will give you the minimum generator output needed to keep those appliances running.

However, you also need to account for the highest starting wattage among those appliances. Many appliances with motors or compressors, such as refrigerators, air conditioners, and power tools, require a significant surge of power to start up. This starting wattage can be several times higher than the running wattage.

To ensure your generator can handle the startup surge, you should choose a generator with a rated output that exceeds the total running wattage plus the highest starting wattage of any single appliance. For example, if the total running wattage of your appliances is 800 watts, and the highest starting wattage is 1,200 watts (for a refrigerator), you would need a generator with an output of at least 2,000 watts (800 watts + 1,200 watts) to accommodate both the running and starting requirements.

By carefully calculating the wattage requirements of your appliances and accounting for both running and starting wattages, you can select a generator that will provide reliable and sufficient power for your needs.

Advantages of Solar Generators

Solar generators like Growatt's 1000W models offer several advantages over traditional gas-powered generators. One of the most significant benefits is their ultra-quiet operation. While gas generators can produce deafening noise levels, often exceeding 60 decibels, solar generators operate at a whisper-quiet level, typically under 30 decibels. This near-silent performance makes them an excellent choice for outdoor activities, camping trips, or residential use, where noise pollution is a concern.

Another compelling advantage of solar generators is their eco-friendly nature. Unlike gas-powered generators that emit harmful emissions and contribute to air pollution, solar generators harness clean and renewable energy from the sun. By utilizing solar panels to charge their batteries, these generators produce zero direct emissions, making them an environmentally conscious choice for power generation.

Additionally, solar generators eliminate the need for gasoline or other fossil fuels, reducing your carbon footprint and operating costs. With no fuel requirements, you can enjoy reliable and sustainable power without the hassle of refueling or the risk of running out of fuel during critical situations.

Runtime and Capacity

A 1000W generator's runtime largely depends on the watt-hour capacity of its battery and the load (appliances) you're powering. Most 1000W models have capacities between 1000-1500 watt-hours (Wh).

For example, Growatt INFINITY 1200 has a 1280Wh capacity, while the upgraded INIFNITY 1300 offers 1382Wh. The higher the capacity, the longer runtime you'll get when powering devices and appliances.

To estimate runtime, divide the battery's watt-hour rating by the total wattage of your load. Let's say you're running a 400W load (e.g. TV, laptop, lights) on the 1280Wh Growatt INFINITY 1200. The formula would be:

1280Wh capacity / 400W load = 3.2 hours runtime

However, most generators are not drained from 100% to 0%. For safety, you'll want to recharge when the battery hits 20%. On the Growatt INFINITY 1200, that's about 256Wh remaining (1280 x 0.2). Subtracting that from the full capacity gives 1024Wh of actual usable power.

1024Wh usable / 400W load = ~2.6 hours runtime

So with a 400W load, you can expect around 2-2.6 hours of runtime from the 1280Wh Growatt INFINITY 1200 before needing to recharge. Lighter loads will obviously extend that time. It's always wise to overestimate your power needs when choosing a generator size.

Portable vs Heavy-Duty Power Needs

While 1000W generators are incredibly versatile for portable power applications, they are not designed to handle the heavy-duty demands of powering an entire household. These compact units are ideal for charging small appliances, electronics, and tools in remote locations or during power outages, but they lack the capacity to sustain the simultaneous operation of multiple high-wattage appliances commonly found in a home.

The 1000W output is well-suited for running essentials like a refrigerator, lights, a laptop, and a TV, but attempting to power energy-intensive devices like air conditioners, electric heaters, or clothes dryers would quickly overwhelm the generator's capabilities. These larger appliances typically require a more robust power source, often in the range of 5000W or higher, to function reliably.

When it comes to portable power needs, such as camping trips, job site operations, or tailgating events, a 1000W generator shines as a convenient and efficient solution. Its compact size and relatively quiet operation make it easy to transport and use in a variety of settings without causing excessive noise or disturbance. However, for whole-house power backup or off-grid living situations, a larger generator or alternative energy system would be necessary to meet the higher energy demands.


What is the difference between starting and running watts?

When powering appliances with a generator, it's important to understand the difference between starting watts and running watts. Starting watts refer to the surge of power required to initially start an appliance with a motor or compressor, such as a refrigerator or air conditioner. This initial surge can be significantly higher than the running watts needed to keep the appliance operating. Running watts, on the other hand, represent the consistent power draw required to maintain normal operation. Failing to account for starting watts can lead to overloading the generator, causing it to shut down or potentially damaging the connected appliances.

How long will a 1000W generator power common appliances?

The runtime of a 1000W generator depends on the specific appliances being powered and their wattage requirements. Here are some examples of common appliances and their approximate runtimes on a 1000W generator with a 1280Wh capacity:

  • Refrigerator (700W): 1.5 hours
  • LED TV (60W): 17 hours
  • Laptop (65W): 15 hours
  • Box fan (60W): 17 hours
  • Coffee maker (800W): 1.3 hours

It's important to note that these runtimes are based on the appliances' running watts and may vary depending on factors such as age, efficiency, and usage patterns. Additionally, starting watts for appliances with motors or compressors will initially draw more power, reducing the overall runtime.

What makes solar generators like Growatt's so quiet?

Solar generators, like Growatt's 1000W models, are incredibly quiet compared to traditional gasoline-powered generators. This is because they rely on lithium-ion battery packs charged by solar panels, eliminating the need for a noisy combustion engine. Solar generators typically produce less than 30 decibels of sound, which is quieter than a whisper. This makes them ideal for use in residential areas, campgrounds, or any environment where noise pollution is a concern.

Can a 1000W generator power a whole house?

A 1000W generator is not designed to power an entire household simultaneously. While it can effectively run several small appliances or devices, it lacks the capacity to handle the combined load of multiple high-wattage appliances found in a typical home, such as air conditioners, electric heaters, ovens, or multiple refrigerators. Powering a whole house would require a much larger generator, typically in the range of 5,000 to 10,000 watts or more, depending on the specific power needs and appliances in the home. A 1000W generator is better suited for powering essential devices during power outages or providing portable power for camping, job sites, or other off-grid situations.


A 1000 watt generator is a versatile and portable power solution ideal for basic energy needs at home, job sites, RVs, or off-grid situations. While it can't handle power-hungry appliances like air conditioners or heaters, a 1000W generator excels at running smaller appliances like fridges, power tools, phones, laptops, TVs, fans, and coffee makers.

By calculating the running wattage of your devices and factoring in the highest starting wattage, you can determine if a 1000W generator meets your power requirements.
