How We Chose the Best Solar Grid Tie Inverters

To find the best solar grid-tie inverters, we began our search by identifying the top leading manufacturers of the best solar inverters.

We narrowed our search even further by finding out which manufacturers carry the best hybrid solar inverters. 

Here at Ecavo, we are most concerned with caring for our planet and remaining as green and eco-friendly as possible.

Therefore, the first thing we looked for in the solar inverters we tested is if they’re eco-friendly. 

For this specific hybrid solar grid-tie inverters test, we paid attention to the price and the following criteria as we ranked.

Wattage Output

The wattage is a key piece of information that you need to look out for when shopping for your solar grid tie inverter.

To prevent the loss of energy, make sure that the watts of the inverter equal the watts of the solar panels. 

We recommend getting a high-wattage inverter with a series of high-wattage panels to maximize your energy production.

Peak Efficiency

The peak efficiency will determine the maximum efficiency the grid tie inverter can achieve when working in ideal environments.

For a grid tie system to meet its rated power, it must have an input that exceeds its output if its efficiency rating is below 100%.

Most solar grid tie inverters are in the range of 90-96% efficiency. Overall, the higher the percentage, the better the inverter.

Inverter Types

Several types of grid tie inverters vary in price and function and offer flexibility to those with renewable energy functions.

Here’s a breakdown of the different types of solar inverters.

Off-Grid Inverters

An off-grid inverter operates independently of the local public utility system, unlike on-grid solar inverters.

They have a unique capability of converting sunlight into DC electricity and storing it in a set of batteries.

When the inverter is being used, it uses DC electricity to produce AC electricity, providing energy to the entire home. 

Micro Inverters

A micro inverter is the smallest grid tied system on the market, both in size and function. This is because they can support just one solar panel at a time.

This is perfect for those living in a tiny home, like a trailer. 

Hybrid Inverters

Hybrid inverters are unique because they allow for both on-grid and off-grid use.

They can be hooked up to the local public utility system and used independently because of the unique energy storage capabilities of the batteries.

They can store energy for future use, so you can still be comfortable in your home when you’re off-grid.

String Inverters

If you’re looking for the least expensive option, string inverters would be your best bet. Staying true to its name, a string inverter supports several solar panels stringed together.

While they’re great in the right conditions, a single panel can shut down your whole system if it fails or is shaded. 

They should only be used in full, direct sunlight that is unobstructed to prevent unintentional failure.

To learn more about how a solar inverter works, check out this article from the Office of Energy Efficiency & Renewable Energy. In rating the best inverter, we gravitated more towards hybrid-type inverters. 

They have the best efficiency and tend to be eco-friendly with their capability of capturing solar power and saving it for later use.

This allows you to maximize your energy production and charge batteries while remaining on-grid.

How to Choose the Best Solar Inverter

We know how overwhelming it can be to choose a solar inverter right for your home. Here’s a breakdown of what to look for when shopping for a solar inverter.

Specs

Each solar inverter comes with a data sheet that provides the details of each inverter. Here’s what to pay close attention to: 

Output Voltage

For residential use, an output of 240VAC is sufficient. Larger commercial energy storage systems will need 208-600VAC.

Rated Output Power

Depending on the output voltage, each inverter will have a different rating. The rating will be in either watts (W) or kilowatts (kW).

Maximum Input Current

This dictates the maximum amount of current the inverter can handle. The current will be lost if the solar array produces more than the maximum input the inverter can use.

Maximum Output Current

This determines the rating of protection devices, such as breakers and fuses.

Where Do You Live?

Energy regulations vary from city to city. Some governments may even offer a tax credit to offer the cost of converting to solar power.

For those living in the US, there is an available federal tax credit program which you learn more about in this article from energy.gov.

Where you live is also important because some solar energy systems require protection from elements like rain, snow, dust, and ice.

We recommend seeking out weatherproof grid tie systems that meet the NEMA 3R/4X standards.

Do You Want The Option To Store Backup Power?

Hybrid inverters are the way to go if you need to store solar power for future use or as an emergency backup.

Typically, they are more expensive, but they come built with the latest technology that allows for you to build a power supply and use off-grid.

If you’re concerned about power outages, this might be a good selection for you. 

Do You Want The Option To Expand Your Solar Array?

If you want to gradually expand your solar array, your best option would be the microinverter.

Being a relatively small grid tie inverter, it connects and controls one solar panel at a time. 

Each microinverter is a separate expense though you will benefit from controlling the number of solar panels in your home and can expand your array with time.
