Most home appliances require alternating current (AC) to operate. However, solar panels generate direct current (DC) like solar cells. Therefore, you need to have a Residential Inverter that converts the DC power generated by the solar panels into AC power that your appliances can use to operate.
When choosing a Residential Inverter , there are many aspects to consider, such as the type and characteristics of the residential solar inverter. Since the power from the solar panels has to go through the inverter, you don’t want to make poor system performance by making the wrong choice. Read on to learn how to choose the right residential solar inverter for your home’s solar system.
1. Know common inverters
Understanding the different types of solar inverters and how they work is crucial. They include:
- Grid-tied inverter – it converts DC to AC and has the ability to interface with the grid integrated. It transmits unused solar energy to the grid and requires no batteries.
- Off-Grid Inverter – Also known as a standalone inverter. It converts direct current from solar cells to alternating current, often capable of powering multiple residential or commercial projects.
- Hybrid Inverter – It converts direct current to alternating current and can be applied to off-grid and grid-tied systems.
- String Inverter – Common in homes, it’s called a string inverter because it has a string of solar panels attached to it.
2.Compare the efficiency of different solar inverters
It is crucial to check the efficiency of different solar inverters and compare them because efficiency is like the soul of all solar inverters. However, you need to be careful when choosing your preferred solar inverter as not all efficient inverters will meet your needs. You can download an app that can help you compare different inverters or visit recommended websites to see new versions.
3.Research the reputation of the supplier
Some brands are well known. However, there are also some that are not very familiar. Research the brand by browsing their official website. Read customer reviews, blogs, reviews or forums to rank them and narrow down your choices. Companies with positive reviews have top-notch reputations and offer great products and services.
4.Consider the basic parameters of different inverters
Solar inverters do not generate electricity, but require certain parameters to operate. Therefore, basic elements such as their output AV voltage, input DC voltage, frequency and appropriate circuitry must be considered. For example, the input and output voltages of a standard residential solar power system should be 24 and 48 VDC, respectively.
5.Check other accessories or tracking devices on the solar inverter
All devices fail over time. However, some solar inverters are equipped with chips or smaller devices designed to track any kind of failure. In the event of a malfunction, these tracking devices send relevant information to the installation company to help you troubleshoot the problem.
You’ll also want to check if the solar inverter offers optional monitoring components that allow you to keep an eye on your solar system. Monitoring equipment will let you know how much power your system is producing on a daily, monthly or annual basis. Some modern inverters even have a mobile app for tracking the efficiency and operation of the system and maintaining solar inverters.
6.Choose a powerful inverter
Inverters are usually installed outside the building. High temperatures generally increase the voltage of a photovoltaic system, while low temperatures decrease its voltage. Exceeding the maximum voltage will damage the inverter. Also, when your system voltage becomes too low, your inverter may stop functioning.
Therefore, it is best to choose a solar inverter that can withstand harsh weather conditions. For example, a robust inverter should have a robust housing or technology that guarantees stable performance even in unforeseen weather conditions.
7.Check the cooling system of the inverter
A cooling system is necessary to prevent overheating. Since solar inverters are installed outside buildings, they generate a lot of heat. So make sure you choose a solar inverter with an efficient cooling system.
For homes that run on solar power, you’ll need a solar inverter that converts the DC power generated by the solar panels into the AC power that most appliances need to run. However, choosing the right solar inverter can be challenging because you need to be familiar with how it works. With the information provided above, you will easily find the right solar inverter.
