What more would you want than a small and efficient inverter? The 600watt power inverter is mediumsized and suitable for mediumduty operations. Its medium size allows you to carry it around more easily. It is economical in many ways but has power limitations. However, it can power several appliances. So, what will a 600watt power inverter run?
Key Takeaways

This article is a guide to all you need to know about 600watt inverters. Also included are the appliances this small and efficient inverter can run, the amps it draws, its efficiency, and the number of batteries you’ll need for your 600watt inverter. Read through.
What Can a 600Watt Inverter Run?
A 600watt inverter has two types of capacity; surge and running watts. The running wattage is the power you need to run the essential functions of an appliance. On the other hand, surge wattage is the extra power you need to start the electric motor in home appliances such as refrigerators. This wattage is usually required for two to three seconds.
The 600watt inverter has a running capacity of up to 600 watts. On the other hand, its surge capacity is 1200 watts (double the running wattage).
A 600watt inverter can power several small and mediumsized appliances. You can use your 600watt power inverter to run the following equipment.
 TV sets
 Sound system
 CFL lights
 LED lights
 Standard desktop computer
 Laptops (some come with USB ports)
 Box fan
 Battery charger
 Portable nail gun
 250w drill.
 Some models have a cigarette lighter cable for lighting cigarettes.
There may need to be more than the 600W inverter to run power tools like an average kitchen fridge. However, it can run the small 12volt camping fridge. This fridge only draws five amps when connected to the 12volt power source. Given that a fully loaded 600watt inverter draws 50 amps from a 12volt battery in an hour, the fridge can run for up to 10 hours.
The 600W inverter can run any appliance with a 600watt running watt requirement and a 1200watt surge wattage requirement. However, you should ensure that the combined appliance load wired to the inverter is below 600 watts to avoid overload.
Of course, for more powerdemanding appliances and power tools, you should look for inverters with bigger wattage.
600 Watt Inverter Amp Draw – How to Calculate
You should note that the amps your 600W inverter draws depend on the load, not capacity. If the load amounts to 440 watts, the inverter will draw 450 watts instead of 600 watts. The formula for calculating amps is as follows.
(Amps = watts/volts)
Let’s say the combined load for your 600W inverter is 450 watts. If the voltage is 120 volts, the amps drawn would be:
Amps = watts/volts
450 / 120 = 3.75
If the same inverter now has a load of 600 watts and is connected to a 120volt power source, the amps it draws will be:
600 / 120 = 5.0
However, things are slightly different when you’re on an offgrid system. Instead of drawing amps in relation to the load, the inverter draws amps depending on the battery voltage. Therefore, for the 600watt inverter connected to a 12 volts battery, the amps it draws will be:
600 / 12 = 50; the inverter draws a continuous power of 50A per hour.
Besides the load and battery voltage, other factors may also affect power consumption. Environmental factors, appliance design, and efficiency may lower or increase electricity usage.
How Long Will a 600Watt Inverter Last?
Your 600W inverter will continue running as long as there is power. Power inverters linked to the ongrid system are always active without a power outage. However, if you link your inverter to an offgrid system, how long it runs will depend on the battery bank size. The battery bank dictates how much power the inverter supplies to its load. Also, the battery cables affect the effective running of the inverter.
Make sure you have a bigger battery if you want your inverter to run for longer. Also, have battery reserve power for power backup while charging the other battery.
Inverter Efficiency – Does It Affect Power Consumption?
Yes, the inverter’s efficiency affects power consumption. Power inverters use power to run internal functions even when disconnected from devices. This power is insignificant as the inverter consumes less power on standby mode.
The primary concern, however, is the conversion efficiency of your inverter. The converter converts DC power into AC power. How much wattage the inverter retains after the conversion constitutes the inverter’s efficiency. Thus, a 90% conversion efficiency converter retains 90% power after converting DC power into AC power.
Use the formula below to determine how much power your 600W inverter requires. (inverter efficiency is 90% at full load)
Watts = total load x (100 + energy lost percentage)%
Therefore, the total wattage will be:
600 x (100+10)% = 660 watts
The inverter uses more watts to compensate for the lost power. When purchasing, it is a good idea to take the inverter efficiency into account; as inverter size grows, so does the requirement for high efficiency.
There are two types of inverters; pure sine and modified sine wave inverters. A pure sine wave inverter is highly efficient as it loses minimal power. It is, therefore, best suited for sensitive electronics. They are more expensive than the sine wave inverter and if you’re looking for a topoftheline inverter for your semitruck, you’ll want to check out the 5000watt pure sine wave inverter.
How Many Batteries Do I Need for a 600Watt Inverter?
Unlike inverters connected to offgrid systems, which don’t require batteries, ongrid systems do. A thing to remember is to ensure that the battery size matches your power requirements.
If you connect your 600W inverter to a 12volt 100Ah battery, the inverter will draw 50A per hour. This means that the battery will run the inverter for only two hours. If you factor in the inverter’s efficiency, this time can be less than two hours. Using this formula, you can determine how many batteries you need to run your 600watt inverter.
You can determine the minimum amps you require using the following formula.
minimum battery amps = Inverter load x runtime/battery voltage
As a result, the minimum amp required to run your fully loaded 600W inverter for four hours on a 12V battery is as follows:
(600 x 4)/12 = 200.
If connected to a 24V battery, the minim amps will be:
(600 x 4)/24 = 100
As the battery voltage rises, the inverter’s wattage capacity also increases. However, the amps drawn are inversely proportional to the battery voltage. For instance, if the amps drawn from a 24V battery are less than the amps, the same load will be drawn from a 12V battery.
How Many Solar Panels Do I Need for 600 Watts?
On a single day, 4,400 watthours for your 600watt inverter. Given that a solar setup can produce 70 mW per square inch and the number of hours of active sun is five hours, the watts produced per hour will be 350mW per day. Hence, you’ll need about 41,000 square inches of solar panels to power your house efficiently. The equivalent solar panel for this area is about 26 square meters/285 square feet.
Is a 600W Inverter Enough?
Whether a 600watt inverter is enough or not depends on your peak power requirements. The information discussed in this article should give you a clear hint of the power you need.
This inverter is handy when you want to spend your weekend away from home. Its portable design allows you to move around with it more easily. You can power several appliances, as listed in this article.
However, I can’t guarantee that the 600W inverter will be reliable for your everyday needs. Six hundred watts is too small to handle some operations, like your refrigerator and other powerintensive functions like remote job sites. You’ll need a larger inverter for a standardsized refrigerator, toaster, or freezer.
