3000 Watt inverters are heavy duty devices capable of running power-hungry appliances like washing machines, microwaves and hair dryers.
Thus, these are ideal power sources for camping sites, RVs and providing back up power to homes in case of emergencies.
In this guide you will find in-depth reviews of 10 of our favorite 3000W power inverters, or if you don't have time to read the full reviews, check out the summary table below of our very best picks.
'Best in class'
'4 power outputs'
You can connect a number of appliances to a 3000 Watt inverter as long as their combined power demand does not exceed 3000 Watts. All electrical appliances have a wattage rating that specifies how much power they need to operate.
This rating is usually available on their labels. It is a conventional practice to have oversized inverters which are capable of handling 15-20% overloads for short periods of time. As per this rule of thumb, a 3000 W power inverter is good for running a load of approximately 2400-2500 Watts.
A 3000 Watt inverter can comfortably power a few lighting loads, a refrigerator, a microwave, a coffee machine and also charge your cellphone and laptop. Of course, specific appliance wattage ratings have to be checked as they may vary from case to case.
Yes, a 3000 watt inverter is capable of running refrigerators which typically have a wattage requirement in the range of 1200-1500 Watts. More power intensive commercial grade refrigerators can also be run. Most large refrigerators have an amperage requirement of 15 Amperes, which can be met by a 3000 watt inverter.
Inverters convert 12 Volt DC from batteries to 110 V AC for running electric devices. The current drawn by 3000 W inverters can be calculated as follows.
Watt (Power) = Volts (Voltage) x Amperes (Current)
Current drawn by 3000 W inverter= (3000/110) A = 27.3 Amperes approx.
