First of all, you need the power of the solar panels and then pick the right solar inverter. For example, a 10kW solar system needs to be paired with a 10kW solar inverter, so that the whole solar system can run safely and efficiently.
Of course, you need to prepare some tools before installing the solar inverter, including screwdrivers, wrenches, insulating tape and multimeter, etc. These tools can be used when you install the solar inverter, and then you should wear insulated gloves during the installation process, so as to minimize the occurrence of electrostatic discharge, and ensure the safety of the operation process to the greatest extent possible.
Secondly, you need to make sure that the installation site meets the safety standards before installation, including the cleaning of the installation site, the most important point is that you have to disconnect the power supply during the installation process to ensure that you will not be electrocuted during the operation, and lastly, if you operate outside, you should make sure that it will not rain on the same day, etc., and these weather conditions may lead to the water inside the parts, which is not conducive to the normal operation of the equipment in the later stage. work.
1.2.1 Review the Solar Inverter Installation Code
Solar inverter installation code of solar inverter installation process and the process of points to note in detail, you must value the content of the code before installation, so that the process of installing solar inverters can be unimpeded, but also to reduce the probability of accidents in the installation of solar inverters, which is very important to you.
1.2.2 Fixing the solar inverter
Fixed solar inverter this step is very important, you need to use a screwdriver to fix the solar inverter in a pre-determined position (usually on the solar bracket), after the completion of the fixed need to check whether there is a loose phenomenon, if there should be adjusted in a timely manner, which can ensure that the solar inverter can work stably in the later stage.
1.2.3 Connecting the solar inverter
The DC input of the solar inverter needs to be directly connected to the solar panel, and in order to ensure the normal operation of the solar system, the solar panel will be connected to the solar inverter through the PV special cable and MC4 connector, of course, you can also add a charge controller between the solar panel and the solar inverter to control the current in the circuit, which can better protect the solar panels and solar inverter.
If it is a grid-connected or hybrid solar system, the AC output of the solar inverter needs to be connected to the power grid, of course, a PV meter needs to be installed between the power grid and the solar inverter (the PV meter can record the amount of power generated and consumed so that you can pay the electricity bill at a later stage), and the other end of the solar inverter needs to be connected to the power source of your home in order to supply power to the loads at your home.
1.2.4 Grounding
In order to channel the current into the ground in time when the solar inverter malfunctions to ensure the safety of maintenance personnel and equipment, you need to ground the solar inverter. Connecting the grounding terminal of the solar inverter to the grounding rod completes the grounding treatment of the solar inverter. Of course, you’d better check the integrity of the grounding system regularly to protect your life and property.
1.2.5 Start-up check
After connecting and checking all the equipment, including no exposed wires, etc., you need to close the circuit breaker of the solar inverter and observe whether the whole solar energy system can work normally, if there is no abnormality after running for a period of time, your solar inverter is considered to be well installed.
First of all, the installation of solar inverter requires a lot of electrical knowledge, if you don’t have this knowledge, you can ask for the help of professional electricians, they can make sure your solar inverter is installed correctly.
Then, the solar inverter will have different degrees of wear and tear under long-term work, it is recommended that you regularly check the operating status of the inverter to ensure that it can work stably, if any abnormalities occur, it is recommended to immediately replace the solar inverter and send it for repair.
To ensure the safety of the process of replacing the solar inverter, you need to disconnect the power supply, and then disconnect the DC input and AC output of the old solar inverter, as well as to disconnect and ground the wires, you can mark the disconnected lines to prevent the installation of the new inverter will be mixed up with these lines, but also can greatly reduce the installation time.
Use a screwdriver to remove the screws on the old inverter and fix the new solar inverter tightly on the position of the original solar inverter to ensure that the new solar inverter is not loose.
Ensure that all the wiring is complete, if damage occurs or excessive aging should be replaced in a timely manner, and then connect the appropriate wiring to the new solar inverter, to ensure that the connection is correct, otherwise a short-circuit situation will occur.
Make sure there is no any abnormal situation close the circuit breaker of the new solar inverter, check the working status of the whole solar energy system, let the solar inverter work for a period of time, if it can run stably, it means that the solar inverter has been successfully replaced.
