Introduction to Solar Inverter:
We see many people using Solar inverters
these days which proves that its necessity has been increased in the
current years. A Solar inverter is similar to a normal electric inverter
but uses the energy of the Sun i.e. Solar energy. A solar inverter
helps in converting the direct current into alternate current with the
help of solar power. Direct power is that power which runs in one
direction inside the circuit and helps in supplying current when there
is no electricity. Direct currents are used for small appliance like
mobile e phones, MP3 players, IPod etc. where there is power stored in
the form of battery. In case of alternative current it is the power that
runs back and forth inside the circuit. The alternate power is
generally used for house hold appliances. A solar inverter helps devices
that run on DC power to run in AC power so that the user makes use of
the AC power. If you are thinking why to use solar inverter instead of
the normal electric one then it is because the solar one makes use of
the solar energy which is available in abundant from the Sun and is
clean and pollution free.
Solar inverters are also called as photovoltaic solar inverters. These
devices can help you save lot of money. The small-scale grid one have
just two components i.e. the panels and inverter while the off grid
systems are complicated and consists of batteries which allows users to
use appliances during the night when there is no Sunlight available.
The solar panel and the batteries that are placed on rooftops attract
Sun rays and then convert the Sunlight into electricity. The batteries
too grab the extra electricity so that it can then be used to run
appliances at night.
Working of Solar Inverter:
Now after knowing what a solar inverter
is, let’s talk about its working. Solar panels produce direct
electricity with the help of electrons that are moving from negative to
positive direction. Most of the appliances that we use at home work on
alternative current. This AC is created by the constant back and forth
of the electrons from negative to positive. In AC electricity the
voltage can be adjusted according to the use of the appliance. As solar
panels only produce Direct current the solar inverter is used to
convert the DC to AC.
An inverter produces square waves or a
sine wave which can be used for running lights, televisions, lights,
motors etc. However these inverters also produce harmonic distortion.
Expensive inverters make use of lots of steps to produce a sine wave and
thus are found in residential solar inverters. Basically inverters
should be a large one so that it supplies enough power to all the
necessary appliances.
An inverter s easy to buy but choosing
the right solar inverter for your appliance is more important. Thus you
must always consult a solar professional before buying on. We know
that the energy derived from sun is solar energy which is one of the
cleanest sources of energy. Also it can be used to provide lighting to
houses.
You can make us of the photovoltaic
tiles that attract energy from Sun and converts it into a clean form of
electricity which can be used to light, houses, industries and
companies. The cells of photovoltaic consist of positive and negative
silicon that is placed underneath a slice of glass. When the protons of
the Sunlight hit the PV cells they knock the neutrons present in the
silicon. Now the negative charged neutrons get attracted to the silicon
but then are held inside a magnetic field. The wires attached on the
silicon catch hold of these neutrons and while connecting to the
circuit, current is formed. This then gives space for direct electricity
and for converting that into alternate electricity an inverter is used
so that the house appliances can run. As mentioned before major of the
house appliances work on alternate current hence an inverter is used to
convert DC to AC.
Solar power apart from making your home appliances work can also be used to heat water and swimming pools too.
How to Make a Solar Inverter?
The energy derived from Sun is a
renewable one and is totally free of cost. We have learnt how the solar
inverter helps in providing electricity and now we shall learn how a
solar inverter is made. A solar panel is capable enough to convert the
heat or energy of the Sun into direct current.
Solar Inverter Design:
To easily understand the construction of a solar inverter lets discuss the following construction sample:-
- According to the circuit diagram initially do the assembling of the oscillator part which consist of the small components & IC. It is finely completed by interrelating the part leads itself and fusing the joints.
- Now place the power transistors into the acutely pierced aluminum heat sinks. This is crafted by cutting aluminum sheet into specified sizes and bending their sides, so that it can be hold tightly.
- Make use of mica isolation kit to fix transistors in the aluminum heat sink, evade short circuiting & direct contact of the transistors from ground & each other.
- Fasten the heat sink congregation to the bottom of a properly ventilated, strong, thick gauge metal enclosed space.
- Also fasten the power transformer next to the aluminum heat sinks by making use of screw & bolts.
- Now join the suitable points of the assembled circuit board & power transistors on the aluminum heat sinks.
- At last connect the power transistor’s productions to the subsequent winding of the power transformer.
- End the assembly by fastening and interlocking the outer electrical fittings such as switches, mains cord, fuses, sockets, and the battery inputs.
- A voluntary solar power supply circuit and a transformer may be
added within to charge the battery when necessary (check diagram).
Solar Inverter Circuit Diagram:
To understand well how to construct a
solar inverter, it is vital to study how the circuit operates through
with the help of following steps:
- N1 & N2 gates of IC 4049 are employed as an oscillator. It carries out the key role of providing square waves to the inverter division.
- N3 to N6 gates are employed as buffers so that the circuit is not dependent on load.
- Continuously changing voltage from the buffer phase is useful to the bottom of the current amplifier transistors T1 & T2. These transistors perform in harmony with the practical changing voltage and boost it to the bottom of the output transistors T3 & T4.
- These producing power transistors swing at a full oscillation, providing the total battery voltage.
- This energy produced is from solar panel & is employed to power the output load.
Solar Inverter Advantages:
After knowing in detail what a solar
inverter is and how different useful it is to make appliances work at
residential and industrial levels we must discuss about the many
advantages of the device.
- Solar energy has always helped in reducing global warming and green house effect.
- Also use of solar energy helps in saving money many people have started using solar based devices
- A solar inverter helps in converting the Direct current into batteries or alternative current. This helps people who use limited amount of electricity.
- There is this synchronous solar inverter that helps small homeowners and power companies as they are large in size
- Then there is this multifunction solar inverter which is the best among all and works efficiently. It converts the DC power to AC very carefully which is perfect for commercial establishments
- This inverter is cost effective i.e. less expensive than generators
- Apart from solar inverters there are other devices too that make use of solar energy namely, solar cooker, heater.
- Solar inverters are the best way and they are better than the normal electric ones. Also their maintenance does not cost much money
Solar Inverter Disadvantages:
- Initially you need to shell out a lot of money for buying a solar inverter
- It will work effectively and produce direct current only when the Sunlight is strong.
- The solar panels that are used to attract Sunlight requires lots of space
- The device can work efficiently only if the presence of the Sun is strong.
- Solar Inverters can work when there is no Sunlight but provided their battery is charged fully with the help of Sunlight.
