An inverter is a device that converts DC (direct current) in to AC (alternating current) which is widely used in homes and for commercial purposes. A solar inverter also works in a similar way only the source of the DC current is different in this case.
A solar inverter is a part of a solar energy setup that consists of photovoltaic solar panels, charge controller and batteries. The photovoltaic solar panel produces variable DC current and the solar inverter converts it into AC current.

Central inverter is the most common type of solar inverter used in homes. Although, a solar energy system requires an elaborate setup, it helps to save money in the long run because the energy used from the sun to produce electricity does not cost anything. In addition, solar energy system can be used to get electricity even in remote locations because it does not require connection to power or gas.
But, when it comes to choosing a solar inverter for your home, it is important to consider a few basic factors such as the type of inverter, its efficiency, its power rating, protection features of the inverter, etc. Click Here to how to choose the solar inverter based on your requirement.

How to Choose a Solar Inverter?
When you wish to have solar inverters in your home, you need to consider the several factors like the types, efficiency, battery life, power rating, and finally the price. Go ahead and read how these factors greatly helps you to decide the right one and also helps in improving the performance of the inverter.
There are 3 main types of solar inverters depending on the output they produce.
- Sine Wave – This is what you receive from your local utility company or from a generator. The best thing about this type of inverter is that it is compatible with almost all appliances and equipments available in the market. Most appliances require sine wave to work to their fullest efficiency.
- Modified Sine Wave – This is almost like sine wave but it has a square pattern. It is compatible with almost all equipments, but the equipments will have low efficiency in case of modified cine wave and as a result they will use more power.
- Square Wave – This is the cheapest type of inverter available in the market but it is seldom used because it is not compatible with most appliances and equipments. It may however be used to run simple tools with universal motors.
Efficiency of an inverter is the ratio of output power to input power. The efficiency of a solar inverter depends on its load. It is never possible to achieve 100% efficiency because some of the power is lost due to heat generated.
An inverter must be able to meet two power requirements – peak power/surge power and typical power. Surge power is the maximum amount of power that an inverter can supply for a short period of time. This surge is required for staring up appliances with electric motors such as pumps and refrigerators. Typical power is the power that an inverter can supply on a steady rate. Typical power is much less than surge power. An inverter with power rating of 50 watts is good enough for home use.
4. Power Rating
Solar inverters come in different power ratings ranging from 50 watts to 50000 watts but a household seldom needs more than 11000 watts power. Almost all standard solar inverters come in 50 to 5000 watts range.
5. Internal Protection Features
It is best to choose a solar inverter that comes with good safety features that protects the components against overload, lightning surges, etc.
6. Battery life
Battery life of an inverter explains how long the device can run using the power supply. In other words, it can be illustrated as the number of cycles it runs or charges the inverter till its end. It is usually expressed in milli-ampere per hour (mah).
My personal advice is to have inverters with the long battery life as it saves lot of power due to the usage of high-end material like lithium-ion, nickel- hydride etc.
7. Manufacturer’s warranty
Manufacturer’s warranty is the another important thing that you should look into before buying a solar inverter. If the product you wish to have or like is from a reputed brand and offers very good warranty services (say.. years), then you can opt for it without any delay.
Beware of brands that offer poor quality products and no warranty services.
8. Affordable price
Last one you need to consider apart from the above-mentioned factors is the price. Your budget on inverters will let you decide your choice and requirements. If you have enough money, then grab the high-end model inverters that have very long battery life and come with advanced options. Otherwise, you can go with the simple models that matches with your needs and also available at very low-prices.
Frequently Asked Questions
1.What is the lifespan of a solar inverter?
Solar inverter has maximum life of 25-years. But most of the branded models tend to have the lifetime of 10-years. Actually the lifespan of the solar inverter completely depends on the factors like maintenance, quality of the material and the battery usage. Malfunctioning of the device (internal circuitry) may also diminishes the life-expectancy of an inverter.
2. How a solar inverter works?
Solar inverter uses an inverting technology to convert the direct current (DC) into the alternating current (AC) that can be fed to the electrical circuits later. It produces different signals like sine or square wave to make the electronic devices run efficiently for a specific purpose and can be adjusted with proper protection.
3. Can you differentiate AC and DC currents?
Alternating current (AC) explains the periodic flow of charges in only one direction. It can also be expressed as the change in the direction of electric current n-times at regular intervals of time. With the help of AC, you can power up the motors and generators of the same device and many other applications like refrigerators, dishwashers etc. that completely runs on AC.
Whereas in Direct current (DC) the flow of charge is unidirectional and offers the constant voltage or current. This mechanism is mostly seen in low-voltage appliances like fuel cells, telecommunication and automotive industry.
4. What should be the size of an inverter you choose?
As we all know that inverter is rated in watts and hence all the inverter appliances have a wattage rating. It may not be same for all electronic appliances and can be calculated as:
Wattage= Power (in watts) = Voltage(volts)*Current(amperes)
Given below table explains the different electronic devices and their wattage readings. Check it out!
|Electronic Appliances||Wattage Rating|
5. How to select the right inverter for home appliances?
If you are planning to have inverter in your home, then you need to select the right inverter as the power required for your home is completely different. So you can’t blindly select the inverters as you need to consider the several factors like battery life, power utilization, efficiency, power backup options, and protection. There are different types of inverters available in the market and you need to select them as per your requirement like for supplying power to ACs, refrigerators, bulbs and outdoor gardening lights, pathway strip lights etc.
6. Do solar inverters produce noise?
Yes, solar inverters do make a lot of noise (expressed in decibels-dB). It’s very horrible to hear it as you may doubt malfunctioning of the device. But it’s actually not. It generally produces lot of noise when used to power high-end products like ACs, refrigerators (25dB).
7. Do solar inverters emit radiations?
No, solar inverters do not produce harmful radiations. As the inverters associated with electrical or electronic device, creates electromagnetic field which does not create any negative effects while using. Hence solar inverters are good to use and can handled safely by the children.
