What is a power inverter? An inverter is a modern innovation that can provide a clean and environmentally friendly electricity supply. It is a tool from a series of renewable energy systems designed to convert direct current (DC) into alternating current (AC), which is used to power various electronic devices found at home. Inverters are an ideal solution for electrical systems that can make users more cost-effective in the long run.
Therefore, several things must be considered when deciding to migrate from the main power grid to a renewable energy system. Here is an inverter purchase guide for you who are interested in starting to use a clean and environmentally friendly electricity system.
Key Factors on How to Select a Solar Inverter
When buying an inverter, it is important to pay attention to some key factors that need to be considered when buying an inverter. This can help you choose the right inverter and have a great renewable energy experience. Here are some key factors on how to select a solar inverter.
Consider the Type of Inverter
Basically, inverters can be divided into 3 types based on the output wave produced, which are pure sine wave, modified sine wave, and square sine wave inverters.
- Pure Sine Wave: characterized by stable, smooth, and harmonious waves, making its use suitable for various types of electrical devices.
- Modified Sine Wave: the wave produced is less stable, and not smooth because the wave is square with a small distance. This makes the modified wave less suitable for sensitive devices but can be used for simple devices such as lights, fans, and others.
- Square Sine Wave: the type inverter wave that is box-shaped and has a sharp point around 90°, so its use is only suitable for some rough and simple loads.
Capacity
Choose an inverter capacity that matches your totaled daily power requirements. Buy an inverter with a capacity larger than 20-30% of the total power requirement to avoid power surges.
Inverter Voltage
Choose an inverter according to the required voltage, usually, inverters have a voltage of 12V, 24V, or 48V. You need to make sure to understand the difference between 12V inverter vs 24V inverter vs 48V inverter to choose an inverter with the appropriate voltage.
Compatibility with Batteries
Pay attention to the compatibility that the inverter has with batteries, this will make it easier for you to choose the best batteries to use in supporting the system based on your preferences and not focus on buying batteries of the same brand.
Efficiency Level
Choose an inverter with an efficiency level above 90% to maximize the conversion process prevent large power losses and save energy better.
Additional Features
Look out for additional features such as security and monitoring features on the inverter.
- Safety Features: Choose an inverter with various safety features, such as overload, overvoltage, overheat, short-circuit, and others to ensure that the inverter can work optimally and can avoid various electrical problems that may occur.
- Monitoring Features: Choose an inverter with smart control and monitoring features, such as using an LCD that shows voltage, battery, and other statistics, or equipped with a remote control for remote controlling. Consider an app-connected inverter that allows you to monitor in real time.
Price and Budget
Set a budget and pay attention to the quality of each product included in the estimated budget. Compare specifications, warranty, customer reviews, and brand reputation.
Step-by-Step Buying Inverter Guide
Here are several things that you need to do before buying an inverter.
- Asses Your Power Need
Make an electrical estimation calculation or estimate of the total daily power requirements and list the important power devices that will be supported by the inverter. This can be a reference in deciding what size power inverter do I need for the whole system in home.
- Research Inverter Types and Features
Learn more about the various inverter types such as pure sine wave inverter, modified sine wave inverter, and square sine wave inverter to fulfill all the devices you have. Also, pay attention to the features provided by the inverter such as security features, monitoring, and built in ports for more ease of use. - Evaluate Efficiency Rate and Durability
Choose an inverter with a high efficiency rate to prevent the inverter from losing a lot of power during the conversion process. Also, an inverter with a high efficiency rate can make it more power-efficient. Besides the high efficiency rate, another thing to consider is the durability of the inverter. Choose a sturdy inverter with certification (IP65 or IP67) that can withstand various environmental conditions. - Compare Brands, Warranties, and Review
Do some research on inverter brands that are known for their reliable performance. Compare between one brand and another, pay attention to reviews given by buyers on applications or forums, pay attention to the features and specifications obtained, and pay attention to the warranty provided by the brand for its inverter products (generally the inverter warranty period is 2-5 years). - Check Compatibility with Existing System
If you already have a renewable energy system, make sure the inverter has good compatibility with your existing power system, such as batteries or solar panels. Also, if the inverter is integrated with solar panels confirm whether the inverter supports grid-tied, off-grid, or hybrid as needed.
