Best Pure Sine Wave Inverter Buying Guide-Things to Consider
If you are planning to purchase an inverter, there are some necessities for a quality one. Otherwise, you might end up with a flimsy type that will not meet your energy needs.
Here are some considerations that you need to make for a quality pure sine wave inverter.
Wattage
Wattage will depend on what you are buying for. This is because different appliances have different wattage requirements.
To find an ideal inverter, we always recommend that you choose one with a slightly higher wattage power than you need, and this will save you from the hassle of under-wattage.
Continuous load and Peak Load
Continuous wattage is the power an appliance needs to run, while the peak wattage is the energy an appliance needs to start. Peak or surge wattage is generally higher than the continuous load.
Therefore, before making a purchase, check on the specifications of your gadgets and see what energy they need to start and run.
Current waveform
An ideal pure sine wave inverter should generate a current waveform, or rather a sinusoidal current similar to what a utility line delivers.
A current waveform is smooth, pure and peaks gradually, and it’s the best for all the AC appliances, especially the modern ones.
Maintenance Options
It’s recommended that a pure sine wave inverter receives regular maintenance.
You can use the Original Equipment Manufacturers, OEMs, plan, but it's rather expensive when compared to hiring a third-party professional.
Cost
Cost also plays a critical factor when choosing a sine inverter.
Generally, the higher the cost, the more features you will get.
Nevertheless, it essential that you purchase a quality product that is not only within your budget but will satiate all your power needs.
Features to Consider
What are some of the essential features to consider when purchasing a pure sine wave inverter?
USB port- A majority of the quality inverters usually come with several USB ports that will allow for the power inverter to charge through it
Air compressor- Air compressors usually feature in high-end models and are essential in pumping stuff like tires.
Display- Display is a convenience feature, which allows you to monitor the state of your inverter
Power jump starter- A power jump starter is a handy feature for those looking to use the inverter to power up a car or battery
Overload Protection-This is a safety feature that improves on the adaptability of your inverter and is handy especially when you plug a high powered device on your inverter.
Solar charging feature- Ideal for those with a green thumb, the solar charging feature is a convenient and useful feature as it uses the solar energy to power its operation.
Defining Pure Sine Wave Inverters
An inverter transforms DC to AC. DC power is that energy, which is stored in batteries like those in cars or boats, while AC, on the other hand, the type of power used to run appliances.
Given it can transform DC to AC, it means that your power options are now expanded and you can now power your appliances using a generator, rather than having to rely on the electrical outlets from the grid.
Additionally, inverters are an essential part of a home solar power system as they are used to convert power stored by solar panels for you to use that power.
Instances When You Need a Pure Sine Wave Inverter
Pure sine wave inverters generate a smooth, and reliable output, free from voltage surges and spikes and are therefore ideal on:
Unlike conventional inverters, pure sine inverters provide better efficiency and with a lesser interference.
How Pure Sine Wave Inverters Work
As we had mentioned earlier, the primary role of pure sine wave inverter is converting DC power to AC, and it is this process that we shall be looking.
It’s a three-stage process of converting DC to Ac Power.
Oscillator stage
The first stage is the generation of oscillating pulses through a transistorized or an IC circuit.
The oscillation generated will then produce an alternate battery with both positive and negative peaks, accompanied by a specified frequency number.
At this stage, however, the pulses are weak and cannot be used for powering up any transformer.
Booster/ Amplifier Stage
It is at this stage that the oscillation pulses are boosted t a higher current level.
Although the energy at this stage is still in AC form, it still has a low voltage, and can therefore not be used for powering any appliance.
Output Transformer Stage
The last stage is where the AC power is applied to the secondary winding of the sine wave inverter’s transformer.
The result is a stepped-up voltage which is sufficient for use for powering your electrical equipment.
Pure Sine Wave vs. Modified Sine Wave Inverters: Which One to Choose
If you are in search of a pure sine inverter, you have probably come across a modified sinewave inverter.
You are probably wondering which is a better option.
Read on.
Pure Sine Wave Inverter
Pure sine wave inverters are ideal for powering the extremely sensitive electronics. In most cases, you find that these electronics require high-quality waveforms with minimal harmonic distortion.
Besides quality and clean power, pure sine wave inverter has a higher surge power, and this is to mean they can easily exceed their watt rate for some time and allow motors to start easily.
Additionally, they are compatible with all devices.
Modified Pure Sine Wave Inverter
These gadgets are manufactured to satisfy the required efficiency of the photovoltaic system.
Leveraging on basic technology to generate power for running simple electronics, these gadgets can operate a variety of loads and is ideal for computers, TVs, microwave oven or even lighting systems.
However, the modified sine wave inverter is quite limiting as it does not operate with most of the modern appliances.
Pure Sine Wave Inverter Advantages
Conclusion
Whether you are looking to power up small or big electronics, while ensuring quality output, the best sine wave inverters will do the task.
Besides, these gadgets will guarantee a smooth sine wave current similar to what you would get when you plug your appliances into an electrical grid.
Plus, you get an extremely stable output, effective for any load.
