The main function of an inverter is to change direct current (DC) to alternating current (AC). The input voltage, output voltage and frequency, in fact the power on the whole all depend largely on the design of the specific device and/or the circuitry.
The inverter itself does not produce any power – instead the power is provided by the DC source. Power inverters are either 100% electronic or they could be a combination of mechanical components such as rotary equipment and electronic circuitry.
Static inverters do not make use of any moving parts in the conversion process, though, as they are just that – static.
A power inverter can be entirely electronic or may be a combination of mechanical effects (such as a rotary apparatus) and electronic circuitry.
General Purpose inverter:
A general purpose inverter is a piece of equipment that is able to offer precise variable control of the speed of a motor.
Inverters are commonly used in a wide range of industrial equipment such as printing presses, fans, pumps, conveyor belts, food processing equipment and construction machinery, although they are used in numerous others, too.
Today’s modern inverters are more diverse in design with added features such as USB interfaces, Ethernet and more; the main purpose it to ensure they are user-friendly and versatile and enable users to make use of remote control.
As inverters become more advances and continuously reaching enhanced levels of performance, these devices are being created in smaller more practical models as usage is becoming more common-place.
Inverters play an important part in solar systems – here’s why:
For those that are not familiar with solar systems and their workings, inverters play a key role in any solar energy system; so much so that they are often referred to as the “brains” of a solar system.
Whether your solar system is smaller and used for household purposes, or whether it is a massive 5-MW power plant configuration, inverters play an integral role in all solar systems.
The basic function is to convert direct current (DC) output into AC – alternating current.
AC is standardised and used by all commercial appliances in the home and in industries.
It is therefore unsurprising that inverters are viewed as being the bridge between the photovoltaic system (PV) system and the energy source.
The advancement of technology has improved in leaps and bounds and today’s inverters offer far more than conversion.
