Pure Sine Wave Power Inverter Reviews

Are you planning a long boat trip, RV, or long camping? Or are you working at a construction site with no generator? It is easy to find yourself away from traditional wall outlets and power grid, but that doesn’t mean you can’t power your electrical devices.

A pure sine wave inverter may well just be the best solution.

Pure sine power inverters are the gold standard in power inverters, like all power inverters they take DC power from the batteries and transform it into AC power. This guide will help you find the best pure sine wave inverter that best suits your needs.

What is a Pure Sine Wave Inverter?

A pure sine wave inverter converts DC current to AC current. They can simulate the AC power that is delivered by the utility and they are used to operate sensitive electronic devices that require high-quality waveform with little harmonic distortion. Additionally, they have high surge capacity which means they can exceed their rated wattage for a limited time.

Pure sine wave inverters are typically more expensive than modified sine wave inverters because of the added circuitry. However, this cost is made up for in its ability to provide power to all AC electronic devices, allowing inductive loads to run faster and quieter, and reduce the electric and audible noise in audio equipment, fluorescent lights, and TVs. 

How to Size Your Pure Sine Wave Inverter?

The best pure sine wave inverter for you should have enough capacity to power all your devices. If you only need to use one at a time, then that is the only one you should look at. It can get a bit complicated as you add more devices but it is still a relatively simple calculation. You will need to figure out how much wattage your devices require.

Usually, this information is printed somewhere on most electronic devices. If you can find the specific wattages for your device, you will want to add them together to get a bare minimum figure. This number will be the smallest possible pure sine wave inverter that could suit your needs, so it is a smart idea to add between 10 and 20% to that number when buying the inverter. 

How many amps does a Pure Sine Wave Inverter draw?

The formula for calculating how much DC amps a 2000 watts inverter will draw is as follow:

Watt (Power) = Volts (Voltage) X Amperes (Current)

Current drawn by an 2000w inverter (2000/110) A = 18.18 amps
