Evaluating The LiTime 3000 Watt 12V Pure Sine Wave Inverter

We are needing to expand our inverter power in our Montana 5th wheel. Our current inverter is used for our residential refrigerator and a few accessories outlets. We also have the need to power our 1800 Watt microwave for lunch stops while towing and Harvest Host overnight stays. With our solar and large 300 amps of lithium batteries, we have ample power to support other 110V AC appliances. Not wanting to change our our current inverter, we wanted to add a second unit dedicated inverter for the microwave. We’re evaluating the LiTime 3000 Watt 12V Pure Sine Wave Inverter to see if it will meet our needs.

The LiTime 3000 Watt 12V Pure Sine Wave Inverter

The LiTime pure sine wave inverter 3000W is reported to efficiently convert 12V DC to 110-120V AC power. Considering this inverter for our use is it’s ability to handle a peak surge of 6000W power while providing clean, stable, and low interference power output for all appliances to operate.

Testing The Inverter

We put the LiTime 3000 Watt 12V Pure Sine Wave Inverter on our test bench to determine it’s standby power requirements and ability to handle high power devices, especially those creating large startup surges. We used a heat gun and a pancake air compressor to generate the compressor surges. The combined usage of both units created 2450 Watts of power and ran continuously without any overload or pause in power by the inverter.

We also connected a small apartment/campus style 110V AC refrigerator to the inverter to determine demand by this type appliance. These refrigerators are very low cost and popular for budget conscious van and bus builders as well as those upgrading older campers. The refrigerator had a 90 Watt demand from the inverter, but the inverter surprised us with it 12V to 110 volt conversion at this low wattage running with a 95% efficiency. Very good news for extend battery life.


Overall the LiTime 3000 Watt 12V Pure Sine Wave Inverter performed very well with the loads we used and our oscilloscope tests showed the inverter provided very clean power regardless of the demand required.

With the rich line of features and efficiency provided, the LiTime 3000 Watt 12V Pure Sine Wave Inverter will be a great addition to our Montana.

Our thanks to LiTime providing the 3000 Watt 12V Pure Sine Wave Inverter for our evaluation. We have provided links below if you are needing more information or wanting to purchase this inverer for your RV, van, or bus builds or if you’re needing high wattage 110V AC power for your off-grid needs.
