10 Best Grid Tie Inverter Reviews and Buying Guide 2019
Most of our home appliances like fan, television, or refrigerator run on alternating current (AC). However, imagine you decide to opt for an unconventional, yet effective way of obtaining electricity such as through electricity panels.
The only problem is that the current generated from such panels is direct current (DC), which is not compatible with any of the home appliances. So, how do you convert the direct current and make it functional with your products?
The answer would be to use a grid tie inverter. This is an intricate circuit that is installed to convert the DC to AC . Grid tie inverters are especially handy for converting renewable energy into DC.
You may have a few questions about the product itself, and this article aims to answer all of them.
What does a Grid Inverter Do
Long answer short, a grid inverter simply does the task of converting the alternating current into direct current, but the procedure of this task is very complex and intricate.
Every electrical grid has been uniquely made, and it is absolutely essential that the inverter has mutual characteristics of the grid to convert the electricity. You do not need to be bored with the complexity of it; however, you do need to know the use of these inverters.
Our general home appliances are manufactured to work under altering voltage and current; hence, AC is the only option. On the other hand, if you are going to produce electricity through a hydroelectric power plant, windmill, or a solar panel, it will be DC.
Likewise, any form of renewable energy will provide you with DC, which is not applicable to our electrical products. In addition, an inverter matches with the grid and coverts electricity. It also doubles up as a safety feature during a power outage.

Accordingly, to prevent overheating, the Enocy has an aluminum shell and cooling fan system that keeps the overall arrangement balanced. This device is also portable and compact.
What Makes a Good Grid Tie Inverter?
The best grid tie inverters in the market need to have some specific qualifications to get the users trust. For example, the grid tie solar inverter should be able to optimize with the solar panels. Similarly, the converters also need to be meticulous about the output it provides. Some key elements that make a good solar tie inverter are:
The output power dished out by the inverters is very important as it will generate the various appliances inside the home and other motors.
As the solar panels are powered through renewable energy, it is obvious that the general power output would be less. Moreover, after conversion from DC to AC, there is a discrepancy of power. Despite that, a good converter should be able to generate at least 500 watt.
The voltage supply depends on the amount of voltage the inverter itself can work with. Some devices come with a clear indication of the specific voltage range it needs.
Some devices also require an initial input voltage to function effortlessly. If the supply of voltage is not adequate, the product will not perform to its peak efficiency and in turn, it will incur a loss in power supply. The voltage supply varies from solar grid tie inverter to micro grid tie inverter.
This is the result of two variables, the amount of energy consumed to the amount of energy provided as output. The efficiency of the device can be an easy indicator of whether the device will suit your needs.
Taking out the natural loss of energy due to the conversion, the best grid tie inverters offer 90 to 95 percent efficiency.
Input and Output Current
Given the main function of inverters to covert the type of current, it is essential for a user to know the range at which the current is provided as an output by the product. It has to be noted that the input and output current will always vary from one another.
Since the inverters are mostly placed outdoor, it comes in contact with wind and dust and water. This can be harmful to the device which is why they need to have higher IP ratings. Higher IP rating means the device has a greater chance to outstand the external environment. IP45 and IP65 are commonly found among the inverters.
Any device that toys with electricity and production of electricity must be given utmost caution. This is why the inverters that the user is willing to buy must be certified under the national council. It is also wise to choose brands that are trustworthy.
