Solar inverters are some of the most important gadgets that most homeowners have been using today. In the simplest terms, they are devices that serve to convert direct current (AC) to alternate current (AC) using solar power. Before going into the value of solar inverters, however, we need to understand the differences between AC and DC power and how a DC to AC conversion helps.
DC power is power that runs in one direction in an electrical circuit and is made possible when there is a power source. For example, your cellphone runs on DC power that is supplied from your cellphone battery (where power is stored) to the specific electronic components that make the device function as it should. The power is supplied to these components in one direction until the battery is depleted and has to be recharged. DC power is required for sensitive gadgets where a steady amount of electricity has to be maintained. If, for instance, you have a CD player that requires 220 volts, you have to use a 220-volt battery for it. If you use a battery that gives less than this, your device will not function completely. If your battery exceeds the requirement, this could result in a burnout and you could end up damaging the CD player. You can use a resistor, but this will mean a waste of voltage.
On the other hand, AC power is electricity that runs back and forth through a circuit and is obtained from electrical sockets. AC power is most often used for household appliances and will supply power at varying voltages and frequency. You can use a transformer to increase or decrease the power supplied depending on what your appliance or electronic equipment requires. Another advantage of AC power is, it can supply electricity continuously unless you unplug your device and you don’t have to deal with DC-running batteries that have to be recharged every now and then.
The role of the solar inverter then is to allow DC-powered devices to run on AC power for the user to enjoy AC’s advantages. The question is, why a solar inverter? There are many advantages to using solar energy. Remember that solar energy is a naturally renewable resource, and even if solar-powered devices may not be very cheap at the moment, long-term savings can still be made because its source is free for all. On top of this, we all know that solar energy is environment-friendly. Obtaining, storing and using it will not result in toxic CO2 emissions which are known hazards to the ozone layer.
A solar inverter can be a better choice for converting DC power to AC power for your home appliances. Also called photovoltaic or PV solar inverters, these devices can help you save mother earth and make long-term savings on your budget.
