Pure Sine Wave Inverter
If you are looking to power any electronic device including the most sensitive ones in your household, pure sine wave inverter is an ideal choice. Reason? It gives smooth, pure wave sine power that is free of distortions.
The inverter also has a high surge capacity that allows them to exceed their rated capacity for a limited period. This trait greatly reduces the time it takes for a motor to start up as it draws up to seven times the rated wattage during start up.
Modified Sine Wave Solar power inverters
It is the most commonly used and pocket-friendly type of power inverter. It produces an AC waveform ranging between a square wave and a pure sine wave. It may not work well with some electric appliances that use motor speed regulators or timers.
True Sine Wave power inverters
This kind of inverter in most cases emits cleaner power than an electric power utility company. It runs any type of AC equipment and is therefore the most expensive; it is nearly twice the cost of a Modified Sine Wave Inverter. It can automatically adjust as the AC loads require. It is the most appropriate for a normal home which uses a variety of electrical appliances.
Familiarize with electrical standards
The input DC voltage must match that of your household electrical system and that of your power bank. At least understand that 12v is no longer the dominant electrical standard for home systems, except for the very simple systems. That said, the most common standard is 24V or 48V. As you may have realized, the modern standard has a higher voltage. This is because, a high voltage systems carries less current making the wiring system cheaper and easier.
Ensure the inverter's AC output matches the conventional power in your local region in order to successfully run locally available appliances. For instance, In North America, the standard for AC utility service is between 115V-230V at a frequency of 60Hertz. This is different in Europe, South America and other places whose standard is 220V at a frequency of 60Hertz.
Lookout for Safety Certification
A good solar power inverter should be certified by an independent testing laboratory such as UL, ETL, CSA amongst others. To identify a certified inverter, look out for the certification stamp on the product. It is the surest way to have a safe inverter that meets the manufacturer’s specification and one that will be approved in case of an electrical specification. Again, designs and ratings vary from country to country and it is imperative to have the right information before making a purchase.
