Operation of a wind/solar grid-tie inverter

Using a grid-tie inverter for a wind turbine or solar is a way to quickly reduce your electricity bills. This device is usable for all types of wind turbines or solar panels.

Operation:

Start by connecting the wind turbine or your solar panels to the grid-tie inverter to make it work. Then, it must be plugged directly into a standard wall outlet compliant with 16A standards.

After these connections, the inverter synchronizes with the voltage and frequency of the grid and injects the current from the installation into the house.
Thus, the incoming meter will slow down and your bill decreases because you primarily consume your electrical production.

Installation:

The installation of this inverter is both quick and easy.
It also helps in transferring energy produced by residential wind turbines into the electrical grid without needing other equipment.

Advantages:

With this grid-tie inverter, you will no longer need batteries as it has the same function as MPPT batteries. It also produces a pure sine wave corresponding to that of the grid. No manual configuration is necessary.

In case you need to send more power into your grid, you have the option to install additional units in parallel.
Also, the grid-tie inverter has overload, overheating, reverse polarity protection functions, and the energy conversion efficiency is very high. And it has a low weight allowing for simplified handling.

Frequently Asked Questions

How does a grid-tie inverter work?
A grid-tie inverter allows the conversion of electricity produced by a wind turbine or solar panels into alternating current directly fed into the domestic electrical grid. It synchronizes with the grid's voltage and frequency and reduces electricity consumption by prioritizing locally produced energy.
How to install a grid-tie inverter?
The installation is simple: connect your wind turbine or solar panels to the inverter, then connect the inverter to a standard 16A wall socket. The device will automatically synchronize with the domestic electrical grid.
Is it necessary to declare the installation of a grid-tie inverter?
In France, it is generally not necessary to declare the installation of a plug & play grid-tie inverter with direct wall socket connection. However, for other models requiring a surge protection box and specific safety devices, a declaration to ENEDIS is mandatory.
What are the advantages of a grid-tie inverter?
A grid-tie inverter allows you to reduce your electricity bill without needing batteries. It produces a pure sine wave, automatically synchronizes with the grid, and has protections against overload, overheating, and reverse polarity.
Can a wind turbine and solar panels be connected to the same inverter?
Yes, it is possible to connect a wind turbine and solar panels to the same inverter, provided that it is compatible and the total power produced is suitable for the inverter's capacity.
What happens in the event of a power outage?
In the event of a power outage, the inverter automatically shuts down for safety reasons to prevent any backflow of current to the grid, thus protecting technicians who might be working on the power lines.
How to maintain a grid-tie inverter?
The grid-tie inverter requires little maintenance. Ensure it is well-ventilated, avoid using extension cords, and regularly check that the connections are tight and the operation indicators are green.
What is the energy efficiency of a grid-tie inverter?
The energy efficiency of a grid-tie inverter is generally high, often above 90%, thanks to the direct conversion of the produced energy into alternating current that can be used immediately.
Can a grid-tie inverter be used without batteries?
Yes, a grid-tie inverter can operate without batteries, as it directly feeds the produced energy into the domestic electrical grid. However, for off-grid use, batteries may be necessary.
