Pure Sine Wave Power Inverter Reviews

Are you planning a long boat trip, a camper or a long camping trip? Or do you work on a construction site without a generator? It’s easy to get away from traditional outlets and the grid, but that doesn’t mean you can’t power your electrical appliances.

A pure sine wave inverter may be the best solution.

Pure sine wave inverters are the gold standard in inverters, like all inverters, they take direct current from batteries and convert it into alternating current. 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 direct current into alternating current. They can simulate mains power and are used to control sensitive electronic devices that require a high-quality waveform with low harmonic distortion. In addition, they have a high peak capacity, which means that they can exceed their capacity for a limited time.

Pure sine wave inverters are generally more expensive than modified sine wave inverters because of the added circuitry. However, these costs are offset by the ability to supply power to all AC electronic devices, allowing inductive loads to run faster and quieter, and reducing electrical and audible noise in audio equipment, fluorescent lights, and televisions.

How to Size Your Pure Sine Wave Inverter?

The best pure sine wave inverter for you should have enough capacity to power all your appliances. If you only need to use one at a time, that’s the only thing to look at. It can get a little complicated as you add more devices, but it’s still a relatively simple calculation. You need to know how much power your appliances need.

Usually this information is printed somewhere on most electronic devices. If you can find the specific wattages for your appliance, add them together to get a minimum figure. This number is the smallest possible pure sine wave inverter to fit your needs, so it’s a good idea to add 10-20% when purchasing the inverter.

How many amps does a Pure Sine Wave Inverter draw?

The formula to calculate how many DC amps a 2000 watt inverter will draw is as follows:

Watts (Power) = Volts (Voltage) X Amps (Current)

Current drawn by a 2000 W (2000/110) A converter = 18.18 amps
