Grid Tie Inverter For Your Home Solar System

If you are thinking about getting a solar power system for your home, one of the first questions you’ll ask is, “how do I get my electricity meter to stop spinning?” You may also wonder how many panels or batteries are needed to power your home and how much it will cost. Many variables determine how much energy comes from the sun and how much goes into your home. Most importantly, though: How does a grid tie inverter work? That’s what we’ll be exploring here today!

They Are Used For Renewable Energy.

The device converts direct current (DC) from the solar panels into alternating current (AC). You can use this AC to power your home or sold back to your utility company for a credit on your bill. Renewable energy systems, including solar panels, wind turbines, and hydroelectric power plants. These systems convert sunlight into electricity or capture wind or water flow to generate power.

The capacity of a grid-tie solar inverter is its ability to handle the amount of power coming in from your panels. For example, if you have 120-watt panels and you want to install an inverter with a 300-watt capacity, that would mean that your system could produce up to 360 watts from the sun—more than enough for all your household needs. This is important because grid-tie systems are suitable for continuous operation, which means that any excess power generated will flow out into the electric grid instead of being stored in batteries or used by other devices.

A large capacity means that your system can accommodate more energy production without upgrading over time; however, it also comes with a higher upfront cost (and may require additional wiring).

It Allows For Expansion.

If you want to expand your system and keep it up to date, this inverter is for you. The ability of your solar energy system to grow over time can be pretty valuable, especially if you’re using a grid-tied inverter.

It Works With Your Power Company.

It must be compatible with your power company. If this inverter doesn’t match up with the frequency and phase of your local utility, it could trip out and shut down.

It must also handle the power your solar panels produce and the power you need in your house at any given moment. Ensuring it can handle great demands from appliances like microwaves and refrigerators and small demands from things like cell phones or laptops charging overnight. The more batteries you have, the better! Otherwise, this could cause problems because if there isn’t enough storage space, those small demands will be met by pulling energy directly from solar panels instead of charging up a battery first.

Different Types Of A Grid Connected Inverter

  • Central grid connected inverter – These are the least common type of grid tie inverters and are typically used to power several residential solar panels.
  • Microinverters – Microinverters work simultaneously with one or two solar panels instead of an entire array. Each panel has its dedicated inverter, which can help reduce losses during transmission and make maintenance easier since you can remove individual panels without affecting other parts of your system.
  • String inverters – These refer to any type not currently mentioned above; they often combine multiple central or microinverters into one unit.

It Serves As An Essential Component Of A Home Solar System.

It’s an essential component of a home solar system. It converts DC power from the solar panels into AC power for home use. Grid-tie inverters work with the local power grid, which can help you reduce your energy costs and increase savings.

Other Applications Of Grid-Tied Inverters

Grid-Connected Photovoltaic Systems

These are the most common type of PV system and are connected directly to your local electrical grid. Grid-tied inverters convert the direct current (DC) from your solar panels into alternating current (AC), which can be used by household appliances and equipment, such as lights, heaters or air conditioners. Also known as “on the grid” or “grid-interactive” inverters, they don’t need batteries because they automatically disconnect from the grid when there isn’t enough sunlight to provide energy for your home or business.

Grid-Connected Wind Turbines

Grid-connected wind turbines generate electricity. These systems transfer the power generated by a wind turbine directly into the grid, where it is distributed to consumers. The voltage from the turbine must be converted and lowered to match that of the grid, which uses an isolating transformer called a “rectifier.” The rectifier works by converting AC back into DC before feeding it into your home’s AC input at 240 volts, which is then converted back into 120 volts AC at your outlets using standard wall sockets and plugs.

Power Quality Operation In Residential Grid-Connected Inverters

Power quality is paramount in residential grid-connected inverters. This is because these inverters are directly connected to a distribution network that carries industrial and commercial loads. With high THD, the power quality of these loads can be affected, causing them to trip out or malfunction and potentially causing significant damage. Several technologies are available to combat this problem and ensure that all loads have good power quality. One such technology is an active filter.


A microgrid is a small-scale energy grid that can operate independently from the main power grid. Microgrids are used for on-site power generation, such as solar panels and wind turbines, and to meet the demand of buildings or campuses with high energy requirements. Remote areas with no access to a large central power source also make use of this.


We hope this article has given you a better understanding of the types of grid tie inverters available. With so many options, it’s essential to understand your own needs. It’s also necessary to work with an experienced installer to help ensure that your system is installed correctly and performs as expected!
