Can you think of even one good reason to NOT have a grid-tie inverter? Neither can we! Grid-tie inverters are the inverters you want to get backup power to your home from the grid. In other words, when the power goes out, you’ll still have power to your home.

Other benefits include:

  • Energy saving
  • No noise and heat
  • Long life span.
  • Low maintenance cost
  • Lower energy consumption(based on inverter model)

Just remember you need to find a high-quality inverter. Don’t settle for less. This article will help you determine the best grid-tie inverter as well as answer some important questions in our FAQ section.

SMA Sunny Boy 7.7-US 7700W Grid Tie Inverter

Specification

Wattage:5000
Volts AC:208, 240
Volts DC:600
Type:Transformerless, Disconnect, Inverter
Item Weight:57 Pounds

The SMA Sunny Boy 7.7-US 7700W is a step up from the slightly older 7.5-US 7700W. Like the 7.5-US 7700W, it is a fully “Grid-Tie” system, meaning it is designed to be mounted on the outside of your home and connected to your existing electrical system with no extra wires or additional hardware. 

That means no noisy, messy, and hard-to-install electrical wires inside your home or garage, and no more need to hire an electrician to add a new electrical feed from the utility pole.

The inverter is designed to be connected to the grid via a dedicated “grid tie” wire and is compliant with the IEEE802.3at-2010 and IEEE802.3at-2011 standards.

WHAT WE LIKE

The SBG77700W is a power conversion module that converts electric power into DC power for use at the battery bank and DC power for use at the load. This 5000 Watt machine is designed to handle heavy duty tasks. When your grid power goes down the Sunny Boy will be right there to power whatever you need it to.

PROS

  • Secure Power Supply provides backup electricity when you lose power
  • Excellent customer support
  • You don’t need the power optimizers that are mandatory with other similar systems

CONS

  • You will need between 4 and 6 solar panels in order for this unit to function correctly
  • The system needs full sunlight, so your panels need to be facing the same direction
  • Can be difficult to install by yourself because of the weight (57 pounds)

The Eco-Worthy 1000W Grid Tie Inverter is SunJack’s first solar inverter to be designed for grid-tie applications, and it’s a good one. It’s rated at a whopping 1,000W continuous, and its build quality is on par with the best grid-tie inverters on the market. 

The built-in display provides loads of information including power generation as well as real-time info on things such as voltage, temperature, and date/time status. 

The unit’s heatsink can get very hot (up to 176 degrees Fahrenheit) in certain conditions so be careful when attempting to touch it.

WHAT WE LIKE

We like that this unit can be connected, or stacked in multiples if you need it for larger arrays. It’s always nice being able to use the same unit in parallel. 

PROS

  • Very easy installation
  • Excellent display with relevant information
  • Stackable design means you can have multiple units for larger arrays

CONS

  • Strangely, the inverter cannot be connected to a battery bank
  • Some buyers have reported quality issues concerning reported power output, but we did not experience this problem
  • Unit can get very hot at times

So, as opposed to a typical PV system, you don’t need to use an existing solar panel to combine solar power with a battery bank. This allows you to pick from a larger selection of PV panels, rather than having to stock up on multiple solar panels.

First, the EpRec 600 can be used to connect a variety of sources to the grid, including battery banks, solar panels, wind turbines, and even small solar water heaters.

Second, this inverter has a maximum power rating of 600 watts, which means it can produce enough power to run small- to medium-sized appliances like a refrigerator and a washer and dryer.

WHAT WE LIKE

The EpRec 600W Grid Tie Inverter came out in the fall of last year and has proved popular. This inverter is a form of grid-tie system that is a completely integrated and stand-alone product.

PROS

  • Simple design and easy to install
  • Performs as expected
  • Light enough to put anywhere

CONS

  • Unit doesn’t seem to come with documentation to explain about the LED lights
  • Can be noisy at times
  • Will not run with 12 Volt battery, need at least 24Volt battery

Type:120 VOLT
Item Weight:63 pounds

The iMeshbean 1000W / 300W/ 500W / 600W models are available for both grid-tie and battery-backup applications. They are designed for continuous solar input and include a self-diagnostics mode for fast troubleshooting.

The 1000W system, for example, is capable of powering a standard household and weighs only 20 pounds. The 1000W system includes one 1000W solar panel, a 20W MPPT switch, and a maximum power handling of 300W. The 1000W system also includes three 10W MPPT chargers, as well as a 1,000W solar charge controller.

WHAT WE LIKE

The iMeshbean Inverters are powerful units that are designed to work with your grid-tie system to maximize your output and come in a handy stackable form factor for easier installation. There are no batteries required to use the device.

PROS

  • Detachable display is nice and easy to read
  • No brainer setup
  • Stackable design

CONS

  • A few customers have reported DOA units
  • We’re not sure if this is a simple misunderstanding, But some purchasers have reported that the unit is inefficient. Our best guess is that you will need a more powerful panel if you need a certain amount of power. For example, if you are expecting 500 watts, then you’ll need a panel that can put out at least 635 Watts.

Frequently Asked Questions

What Are Grid-Tied Systems?

Grid-tied systems are energy storage systems that operate with a source of electrical power that is connected to the grid. The inverter that connects to the grid converts this variable supply into a fixed output that can be used for a wide range of equipment. The inverter switches on and off as the grid supply changes, which steps up and down like a battery to provide consistent power. Transformer-based systems convert the grid supply into a constant voltage and are not considered grid-tied.

A grid-tied system is a solar installation where the inverter acts as a charging battery so that you never have to worry about a dead battery in the middle of the day. (Though you can still charge the battery using the solar panels.) 

Compared to a traditional AC and battery combination the grid-tie system is more efficient because it uses less energy to charge the battery and keeps it charged at all times, even when the solar panels aren’t producing power.

Which Grid-Tie Inverter Should You Choose?

If you’re in the market for a new grid-tie inverter, you may have a difficult decision on your hands. Which inverter should you choose? Should you choose a brand new inverter, or should you choose an existing inverter that’s been updated? 

Which model of the inverter will be right for your application? What are the differences between inverters? What’s the best inverter for your needs?

A grid-tie inverter must be capable of responding quickly to changing power demands by automatically adjusting the current draw. Additionally, it must be able to deliver the most energy possible with the lowest amount of weight and space.

Conclusion

Thanks for sticking with us to the end. We hope you enjoyed this article on the best grid-tie inverter. Our top pick of this round goes to the SMA Sunny Boy 7.7-US 7700W Grid Tie Inverter. It has massive amounts of power but at the same time remains highly reliable. We fully recommend this product.
