How to Choose a 3000w Inverter.
The very first thing you must consider when choosing a 3000w inverter is your intended use for it. What appliances or tools do you intend to use with the inverter? You have to answer this question so you can determine how much power you need. Checking reviews at Amazon.com is always a good idea to help make an educated decision, too. The size of the inverter that you will need is going to depend on the wattage of the appliances or tools that you want to run. Then, you must purchase an inverter that exceeds your maximum wattage by at least 10% to 20 %. For instance, you will need at least a 440 watt inverter to power a 400 watt power tool.

How do you determine the total wattage of the appliances and/or tools that you need to use? First, you need to know to things — the starting (peak) load and the continuous load of every tool or appliance. The starting (peak) load is the initial surge of power needed to start up an appliance or tool. The continuous load is the power needed by the appliance or tool to continue running.
To get the approximate continuous load in watts, multiply the continuous load in Amps by 120 volts (AC voltage). For instance, if a refrigerator has a continuous load of 4 Amps, its continuous load in watts is 480 (4 Amps x 120 volts).
Most appliances have a starting load that is twice the size of their continuous load. Thus, if a television has a continuous load of 100 watts, its starting load would be 200 watts (100 watts x 2).
However, appliances with induction motors such as freezers, refrigerators, air conditioners and pumps have staring loads that are three to seven times higher than their continuous loads. In the above example, the refrigerator would have a starting load of at least 1,440 watts (480 x 3). Remember, the total starting load is the number that you need to take into consideration when choosing the size of the inverter that you are going to purchase.
It only makes sense to choose a high-capacity inverter over one with a lower capacity. You may need to run more appliances in the future. With a high-powered 3000w inverter, you will not need to buy a new inverter. You will save money in the long run.
High Capacity 3000w Inverter Brands to Consider
There is a whole jungle to navigate when you’re looking to buy a 3000 watt inverter. These two are pretty much regarded as two of the best on the market today.
Whistler Pro-3000W 3000 Watt Power Inverter
This inverter is easy to setup and fairly simple to use. It features the “Smart Surge Control” which attempts to start loads above its continuous rating for up to 10 seconds. This is useful when starting old motors or compressors. It has 3,000 watts continuous power and 5,000 watts surge capacity (peak power). It has a USB port for USB-powered gadgets, current overload protection, low and high voltage protection, over-temperature protection and a thermostatic-controlled high speed cooling fan to prevent overheating.
Xantrex Freedom 3000 Watt Pure Sine Wave Inverter
This Xantrex model is easy to configure. It charges dual 12 volt batteries quickly. The built-in transfer switch automatically shifts from inverter power to incoming AC power and back. It operates in virtually all climate conditions and can withstand low temperatures between -4 degrees to -140 degrees Fahrenheit. The coated circuit boards protect the machine from humidity.
