When you are going to install a solar inverter, you may only know that the function of the inverter is to convert DC power to AC power, and you may not be clear about the configuration of the inverter. But it doesn’t matter. In this article, we will go through the configuration connection and other issues related to the inverter with you.

1. How to connect the solar inverter?

First of all, you need to connect the output wire of the solar panel to the input of the solar inverter. When connecting, you need to pay attention to whether the voltage and current of the solar panel are in line with the input of the solar inverter, so as to avoid the damage of the components in the solar system.

After that, you need to choose whether you want to connect to the solar battery or the grid according to the type of your solar system. If you want to connect to the solar battery, you just need to make sure that the positive and negative terminals of the solar battery are correctly connected.

If you’re connecting to the grid, the common types of connections are islanded and grid-tied. It is mainly based on the type of solar system you have that you choose the right connection method. Grid-connected is for grid-connected solar systems to directly feed the electricity generated by the solar panels into the grid. The islanded type needs to be used with an energy storage system to guarantee that it can still be used properly in the event of a power outage.

2. How to connect the solar panels to the inverter?

Connecting solar panels to an inverter also depends on the type of inverter. However, during the connection process, it is necessary to use MC4 connectors to connect the positive and negative terminals of the solar panel to the “PV+” and “PV-” ports of the inverter respectively.

For centralized inverter, this kind of inverter is mainly used in large-scale PV power stations, where multiple solar panels are connected in series first, and then connected in parallel to a single centralized inverter in the form of a string.

String inverters are used to connect solar panels in series and then connect them to the inverter one by one, which optimizes the efficiency of the inverter and allows the whole solar system to work normally even if some of the solar panels fail.

Micro inverter is to connect one solar panel or several solar panels to one inverter, so that the inverter can realize the maximum power electric tracking for each solar panel, and improve the overall power generation efficiency of the solar system.

3. How to connect a wind turbine to a solar inverter?

When connecting a wind turbine to a solar inverter, you cannot connect the wind turbine to the solar inverter directly. So you need to connect the wind turbine to a solar controller, which is similar to a battery charge controller in that they both control the current and voltage ranges. After that, you will need to connect the inverter to the solar controller, and this will complete the connection between the wind turbine and the solar inverter. You can also connect a solar panel between the wind turbine controller and the solar inverter or connect a solar panel at the lower end of the solar inverter.

4. Can I connect the solar panels directly to the inverter?

Yes, for both solar panel and solar inverter, they have inputs and inputs, so you can directly connect the positive and negative terminals of the output of the solar panel to the positive and negative terminals of the input of the solar inverter using a cable.

5. How to wire the solar inverter to the breaker box?

When connecting the solar inverter to the breaker box, you need to make sure that the inverter and the breaker are in a power-off state, connect the wires to the output of the inverter, and then, you need to use the connector to connect the inverter to the breaker. In the process of connecting, you need to pay attention to the positive and negative markings on the DC terminal block of the inverter. You also need to follow the instructions carefully to ensure that the connections are correct and all connections are fixed.

6. How to connect the generator to the solar inverter?

There are several ways to connect the generator to the solar inverter just like the solar panels to the inverter, generally there are direct connection, connection through the batteries and parallel connection.

Direct connection: You just need to find the output of the generator and connect it directly to the input of the inverter.

Connection through battery: you first connect the output of the generator to the battery charge controller, and then connect the output of the battery charge controller to the input of the inverter.

Parallel connection: this kind of connection is not often used, you need to connect the output of the generator and the input of the inverter in parallel, and then you need to use the parallel connection to connect the inverter and the load. This type of connection requires that the voltage and current of the generator as well as the phase should match exactly with the inverter’s driving parameters, otherwise the inverter will not work properly.

7. How to connect the solar inverter to Wifi?

Before connecting the inverter to WiFi, you need to have a WiFi collector, this WiFi collector is a bridge to monitor the inverter data. After that, you just need to plug the WiFi collector into the WiFi port. Download the related app on your cell phone or computer, you can detect the working status of the inverter in real time.

8. How to connect inverter and battery

When connecting the inverter and battery, we first need to choose the cable with suitable specification to ensure safe, stable and efficient power output. Then you have to use the cable to connect the negative terminal of the battery to the negative terminal of the inverter input, and also connect the positive terminal of the battery to the positive terminal of the inverter. If you need to connect more than one battery to the inverter, you can choose to connect the batteries in series first, that is, the positive terminal of one battery is connected to the positive terminal of another battery, and finally the remaining two positive and negative terminals are connected to the inverter respectively. During the connection process, be sure to pay attention to the distinction between positive and negative poles and test the inverter and batteries after the connection is completed to see if they work properly.

9. How to turn on the solar inverter?

You have to turn on the switch of the solar inverter, observe whether the indicator light of the inverter is on, if the indicator light of the inverter is not on, you also need to test whether the power supply of the inverter is normal, wait for a few minutes, if you observe that the operation indicator light of the inverter becomes bright, it means that the inverter has started normally. Then you can connect the other PV modules.

10. How do I turn off the solar inverter?

Before switching off the solar inverter, you need to disconnect the grid and the load, and then turn off the circuit breaker. Next, you can stop the inverter by using the main switch or the button on the back of the inverter. However, you should note that the inverter can only be turned off when all the lights on the inverter are off.

Conclusion:

The above is about the configuration of the inverter, we have a detailed description of the inverter connections and inverter switch settings, these solutions will bring more convenience for your inverter.
