When the photovoltaic inverter fails, what aspects can be checked and repaired

The photovoltaic inverter is the core component of the photovoltaic system. It can convert direct current into alternating current, and can also provide feedback to the user about the operating status of the system. However, when you use it, there will inevitably be some problems. I will give you the details today. Introduce the common problems and solutions of photovoltaic inverter use.

1. How to modify the voltage of the boot. Many friends don't know how to modify the power-on voltage when using the photovoltaic inverter. In fact, this can be done by selecting the settings in the user interface, then entering the password, and then clicking the power-on voltage to change the power-on voltage. The input value must be within the allowed range. If the input value is not allowed, it cannot be successfully input. This is a point to pay attention to.

2. What's the matter with the obvious decrease in power generation? Since the battery pack of the photovoltaic inverter has a wooden barrel effect, its power generation is reduced, usually due to foreign matter or uncleanness on the surface of its components. At this time, you can wipe the surface. After wiping it clean, see if the power generation has increased. If the power still does not increase significantly after wiping, you can check whether the shadow is blocking the photovoltaic panel. At this time, you need to remove the shadow in time, otherwise, hot spots will occur, which will affect the service life and power generation of the photovoltaic inverter. amount.

3. How to use the LCD display? This can be achieved by moving the cursor, for example, you can move the cursor up or down, or click the OK key, if you click the ESC key, it will move the cursor forward or back.

When you use photovoltaic inverters, if you encounter the above problems, you can solve them according to the above methods. If you want to check the power generation, you can click Statistics on the user interface to see the power generation of the day. amount, as well as the content of this week and this month, this year, and the total power generation.
