In general, there are two main types of the sine wave inverters. One is the modified sine wave inverter that is able to run just the basic devices and not the highly advanced devices. The other one is the pure model that can run all such appliances.
At some point or the other while you are in the market for purchasing an inverter or just searching for the same on the web, you would have come across the two common names- pure sine wave and the modified square wave inverters. Let us take a look at the key points of difference between the two of them.
The square wave or the modified sine wave devices produces a square wave form. The buyers may face a lot of difficulties in running sensitive appliances such as magneto-optical hard drives, laser printers, photocopiers, power machines using "solid state" power or uneven speed control, battery chargers for the cordless devices, sewing machines with microprocessor control, hospital equipments and others. Even the simpler devices such as television sets and lights with standard ballasts, digital clocks with radios, etc. also face interruption when running on square wave model. These models are generally shielded by standard fuses which, under normal situation, are not always quick enough; as a result they are considerably more at risk of failure.
As against the square wave model, the pure sine wave model is the excellent form of wave that is produced from an inverter and which can power any kind of appliance ranging from the simple light to most complicated ones like big machines and hospital equipments and that too in an extremely efficient manner without any disruption or overheating. Using this inverter means that the user is avail a number of benefits. First of all, the waveform from a pure sine wave device has a very low level of harmonic distortion. One is able to run appliances with inductive loads, for example, motors and microwave ovens, smoothly with such device without any noise and excessive heat. In addition, when the appliances such as fluorescent lights, fans, Game consoles, Fax and answering machines, audio amplifiers and others are running on the pure waveform models, the electrical and audible noise generated in these appliances is reduced to a large extent. What's more, the chances of crashes in computers, glitches and noise in the monitors and unreadable print outs are minimized by this inverter. The highly sensitive devices are safeguarded from the unstable voltage levels, overload and over temperature conditions.
According to your needs, you can choose the type that is ideal for you. When you go out in the market for buying a sine wave inverter, you will find them in a great number of sizes offered by host of digital inverter manufacturer. The size of the system that you go for is based on the power in watts of the device you need to power.
