First of all, we need to have an understanding of the role of inverters in solar energy systems:
An inverter is a key component in a solar energy system that converts the direct current (DC) electricity generated by the solar panels into alternating current (AC) so that it can be used by a home or business. Solar panels can only generate direct current, whereas appliances used in homes and businesses require alternating current. The job of an inverter is to convert the direct current generated by your solar panels into alternating current so that your home or business can use it. In inverter selection, the efficiency of the inverter is also a reference item. The higher the efficiency of the inverter, the more AC power it converts and the less DC power is wasted. The price of an inverter also varies based on its efficiency. High-efficiency inverters are usually more expensive, but they can save money on your electricity bill and extend the life of your solar panels.
How to choose the solar inverter that suits you:
First we need to understand several common types of solar inverters:
Three-phase inverters: Three-phase inverters can power three-phase appliances in the home, such as air conditioners, electric vehicle chargers, and power tools.
Micro-inverter: A micro-inverter is a new household solar inverter that has emerged in recent years. It is small in size and light in weight, and can be installed directly on the solar panel without using a solar distribution box.
When selecting a solar inverter, the following factors need to be considered:
Power of solar inverter
household power consumption
Is there a demand for electricity sales?
Is there a need to store electricity
Inverter Price and Maintenance Cost
According to different usage scenarios, the following inverter types can be obtained:
Hybrid inverters help store excess solar battery systems for their own use. A hybrid inverter can provide a small amount of backup power during an outage, or it can act as a standard solar PV inverter, exporting excess solar energy to the utility grid.
Conventional or off-grid inverters are an excellent choice for ships, commercial buses, mountain cabins, RVs and vacation homes, as well as for potential power outages. Off-grid inverters cannot be synchronized with the grid, but draw power from batteries instead of working with the grid.
Grid-connected inverter The grid-connected inverter or grid-connected inverter supplies power to the grid according to the corresponding phase and frequency. These inverters draw power directly from the solar panels when solar power is available, and automatically shut down if the utility loses supply.
Each solar panel has a microinverter. A microinverter converts DC power to AC power and routes the aggregated output to the grid or battery pack.
Microinverters are small, portable and have all the features of a central inverter. High performance and compact size, micro inverters work well in various applications.
Central inverters or large grid inverters are utility-scale inverters ranging from hundreds of kilowatts to hundreds of megawatts. The central inverter combines all the DC power it receives from the solar panels and converts it to AC power, all at once.
A string inverter is connected to a string of solar panels called a "solar array". Generally, a solar array consists of 15 solar panels. A string inverter combines the DC power it receives from a solar array and converts it to AC power.
This type of inverter is mainly used in commercial and residential solar projects such as garages, rooftops, ground mounts and tracker installations.
So far, I think everyone has been able to choose an inverter that suits them according to their own situation. Do you know any well-known brands of excellent inverters in the North American market? Next, let us learn about some well-known inverter brands in the North American market!
