Importance of Solar Inverters

Importance Of Solar Inverters

In order to ensure your solar panel system is creating usable electricity, you’ll need a solar inverter or micro inverter system. This is because inverters take the DC power created by your system and turn it into AC current that can power your home and be sent through the electricity grid.

Electricity inverters are in a class of electronic devices known as power electronics, and this class of devices is used to regulate power flow. In the case of a solar panel inverter, it takes Direct Current (DC) and converts it into Alternative Current (AC). This is important because DC current only operates at one voltage, and it only moves in one direction. By contrast, AC current alternates and can flow in both positive and negative directions. It’s also important to note that homes, businesses, and the electrical grid only work with AC current, so without an inverter, your system doesn’t have the ability to create usable electricity.

Solar inverters are specifically designed and tested to work with solar panel systems. While other types of inverters convert DC to AC current, they may not work with a solar panel array. For that reason, it’s best to choose an inverter from a reputable dealer, like MJJ’s.

There are three types of inverters, including string inverters, optimised inverter systems, and micro-inverters. The size and layout of your system will determine which products are needed.

String inverters are the most common types of inverters on the market, and the technology is the oldest, which means it’s a proven technology. String inverters get their name from the way most panels are installed. For example, when you look at solar panel systems, you’ve probably noticed that they tend to be set up in rows. Multiple strings of panels can be connected to a single string inverter. These work well for panels that are always in the sun and for properties that don’t have many rooflines.

A micro-inverter is a small inverter that is connected to each panel. This means that if you have 10 panels, you’ll have 10 micro-inverters. These are used to convert DC electricity to AC electricity at the panel, and all electronics are located on the roof. Micro-inverters are often used in areas where there may be uneven sunlight across the solar array, which could result in uneven power generation. Mirco-inverters are also a great option if you think you might want to expand your system in the future.

Power optimisers are a newer technology. They aren’t inverters, but they do help move the power to a string inverter. When a solar panel system employs the use of power optimisers, each panel gets a unit, and the units help move the power to the inverter. Adding optimisers is typically recommended when the panels are partially in the shade, or some panels are oriented differently than others.

When it comes to installing the correct inverter, our Solution Consultants take many factors into consideration, including your power generation needs, your property or roof where the panels are installed, and the layout of the panels. Once all the specifics of your system are known, we can recommend the correct inverter. If you have any questions about inverters or your solar energy system, we’d be happy to answer them.

With some systems, you can monitor the power generation of the entire solar array or each individual panel in order to better understand how much electricity is being created. If you need live WiFi monitoring, let us know so that we can recommend the right models of equipment.

Inverters come in a range of size ratings, from 3kw up to 110kw. Residential inverters generally range between 3kw and 10kw, however, this can be greater depending on the phases available on your property. Commercial inverters are typically between 30kw and 110kw ratings. If you are concerned about the physical size of the inverter, we’d be happy to explain our inverters and where they are typically placed in your home.

Not all inverters work with a solar battery system. If you plan to install a battery along with your panels, please let us know so that we can help you choose the correct inverter.

Your inverter is part of your solar panel system and is installed at the same time. It typically takes one to two months to install a solar panel array from the initial meeting to the finished installation and connection to the grid. If you need a new inverter or want to expand your system, please contact us for more information.

We source inverters from China, South Korea, Australia, Canada, and the United States.
