Intro to 1500 Watt Pure Sine Wave Power Inverters
1500W power inverters are designed to power 120V AC loads from 12V, 24V, or rarely 36V and 48V DC batteries in situations when mains power is not available, like during blackouts, emergencies, camping, tailgating, RV, and other off-the-grid situations.
1500W power inverters usually feature two (2) or more 120V AC ports, but very often one (1) or more USB charging ports, allowing the user to charge USB-charged devices directly.
While modified sine wave power inverters are suitable for resistive loads and some tools and appliances, pure sine wave inverters feature very low THD levels and can be used to power sensitive electronic devices, laptops, TVs, multimedia, etc.
To provide power to tools and appliances that require more power when starting, 1500W power inverters have "surge power" usually around 3000W - they can provide up to 3000W (model dependent) for a very short period of time.
Note: a 1500W power inverter that is constantly loaded with 1300-1500W is not the best choice - as a safety margin, always go for a slightly larger unit; for example, if You need a constant 1500W output, go for a 2000W or even a 3000W unit. But, for 1000W loads, 1500W power inverters are an excellent choice.
But, in order for a power inverter to provide such power, even for a few very brief moments, the battery (or battery pack) also must be able to provide such power (increased by thermal losses in the power inverter).
While lead-acid batteries are not that sensitive to surge power, lithium batteries with built-in Battery Management Systems (BMS) can cause issues if their output power is lower than required - in such situations, BMS will protect the battery and cut off the power to the power inverter, which will then cut off the power to the external load.
While lithium batteries are highly recommended as power inverter batteries, they must be carefully dimensioned in terms of capacity, continuous load, parallel/series connections, surge load, etc.
Note: Even when on idle, power inverters require some power. This power, regardless of how small it is, can drain the battery pack; thus, when power inverters are not in use, turn them off.
To increase safety, most power inverters come with safety features that include over-power/over-current shutdown, thermal shutdown, over-voltage, and under-voltage protection; again, this is model dependent.
While electronic protection is a must-have feature, power inverters should also feature classic circuit breakers - if the current is too high and over-current protection is not activated on time, circuit breakers will trip, protecting the battery pack, power inverter, external load, and probably the user.
Here is our list of "the best" 1500 Watt pure sine wave power inverters, with their short reviews and recommendations - when choosing "the best" unit, choose according to your own preferences and requirements.

Frequently Asked Questions (FAQ)
Here are some of the most popular Frequently Asked Questions (FAQ) regarding 1500W pure sine wave power inverters, but also power inverters in general.
1500-watt inverter, what can it run?
1500-watt power inverter can run any device that features a continuous power less than 1500W and a surge power less than the surge power if the power inverter in question - usually, the surge power of 1500W power inverters is ~3000W.
However, don't forget that the battery (or battery pack) also must be able to provide such power.
How much current does a 1500W inverter draw?
1500W power inverter input current depends on its output power and its energy efficiency. For example, 85% energy-efficient power inverter that provides 1500W draws @12V:
I (A) = (1500W / 0.85) / 12V = ~147 Amps
Similarly, if the power inverter features surge power of 3000W and 85% energy efficiency, for a very short few moments, the power inverter will draw double the current (~294 Amps).
How long will a 1500-watt inverter run? How many batteries do I need for a 1500-watt inverter?
Power inverter runtime depends on the battery energy capacity (voltage, capacity, discharge characteristics, etc.), power inverter energy efficiency, and actual load.
For example, if the user has a 1500W power inverter that features an energy efficiency of 85% and the user wants it to provide 1500W for two hours, the user would need:
E (Wh) = (1500W / 0.85) * 2h = ~3530 Wh
The capacity (Ah) of the battery depends on the battery and inverter voltage:
C (Ah) @12V = 3530 Wh / 12V = ~295 Ah
C (Ah) @24V = 3530 Wh / 24V = ~147 Ah
C (Ah) @36V = 3530 Wh / 36V = ~98 Ah
Note: Most 1500W power inverters are 12V units, but there are also 24V units, while 36V and 48V units are relatively rare.
So, for a 12V 1500W 85% energy efficient power inverter, one would need a single lithium 12V 300Ah battery. If longer runtime, one can go for either an even larger battery or can consider connecting more batteries in parallel.
For more information about such batteries, feel free to check our Best 12V 300Ah and 400Ah Lithium Deep Cycle Batteries article (link opens in the new window).
How to install a 1500-watt power inverter?
First of all, check the Owner's Guide/Manual that comes with the unit.
Generally, power inverters are placed as close to the batteries as possible, preferably in a well-ventilated area in the position recommended by the manufacturer to improve passive cooling.
Since power inverters draw some current even when the load is zero watts, they should be turned off when not in use - they should be placed so that they can be easily turned off either directly or via a remote control device.
Also, for maintenance purposes (replacing fuses, for example), they should be placed in an easily accessible area.
Will a 1500-watt inverter run a 1000-watt microwave?
Yes, a 1500W pure sine wave power inverter can easily power a 1000W microwave oven.
If You are unsure about the wattage of your microwave oven, check the small label on the unit, which usually can be found on its backside.
For more information about this topic, feel free to check our Off-the-Grid: How Many Watts and Amps Does a Microwave Use? article (link opens in the new window).
Will a 1500-watt inverter run a refrigerator?
Yes, a 1500W power inverter with 3000W surge power can easily run most household refrigerators easily, even the older ones.
Since newer refrigerators are more energy-efficient units, a 1500W power inverter can run even more than one such refrigerator - when connecting the new loads, always start with the largest ones.

Few Final Words
1500 Watt pure sine wave power inverters are versatile devices able to support relatively large loads - they can power most home devices, appliances, gadgets, some tools, and similar.
When powering various tools, be sure that the power inverter is strong enough for such operation and that the battery (or battery pack) can support such load.
When looking for a new 1500W power inverter, choose according to your needs and requirements. And whatever You do, stay safe - it is your own responsibility ...
