The Most Common Solar PV Inverter Problems – A Simple Guide For Inverters Problems

The solar inverter is composed of many electrical components. It is a major element of the AC balance of the system, as PV inverters are responsible for taking the output power from the PV panels and converting it into an accurate AC pulse. The AC pulse has a precise frequency of 50/60 Hz and delivers that perfect output into the AC-driven appliances to energize them. The whole process should be done smoothly by the PV inverters. However, for any reason, if the solar inverter is not doing its job smoothly, then there must be malfunctioning or Solar PV Inverter Problems. So on this page, we will dive into the PV inverter's issues responsible for the solar inverter not working? We'll go through the most common Solar panel inverter problems with solar inverters and how to fix them.

However, Solar Panel Costing is an affordable and reliable solar PV system consulting, installation, repair, and maintenance company that is experienced in work from installation to repairing. As per your property's panel requirement, you can estimate the Solar Panel Cost Calculator cost per required kWh on the Solar Panel Costing page. Contact us to book a services survey.

The main problem with solar inverters is that their performance varies due to various reasons such as:

- Manufacturing brand of both Solar Panel and the solar inverter itself
- wiring used in wiring system ( 10 - 12 standard wire gauge)
- Location of installation - whether it is exposed to direct sunlight or place dampness or air flow etc
- Lack of maintenance – Dust and debris accumulation
- System failure during a power outage
- Poorly manufactured and used electrical components in the inverter
- Loose and Faulty Wiring

5 Common Solar PV inverter Problems

Wrongly manufactured

The second problem with a solar panel is that it may be wrongly manufactured. To ensure your solar inverter is working correctly, connect it to a battery with a wire — if the inverter turns on, it's working correctly.

LED indicator

First, if you're having trouble with your solar inverter, it's essential to diagnose the problem immediately. Look out for any red lights or flashing lights on your inverter panel, and make sure that none of them are blinking or flashing too quickly. If they are, contact inverters fault analysis specialists as soon as possible. Suppose you are searching for the most effective Solar panel inverters services in the UK. Then you may engage with Solar Panel Costing since they provide the best Solar inverter panel maintenance and repairing services in UK towns for both commercial and residential levels.

Check wiring

The problem would be loose connections that you can tighten up. Check the wiring between the inverters and the battery and the short, open, or flexible connections. Check the label configuration of wires, it should be dry. If there is a short connection due to dampness, it would lead to hazards and can lead to electrocution. Check if there's any evidence of corrosion. Corrosion can cause Solar panel inverter problems with an inverter. Do it carefully, or take assistance from the inverter fault detector specialist, as they do it better than you with considering safety and security risks and measuring tools. However, Solar Panel Costing helps you provide all the information about the solar inverter installation and inverters inspection, repair, and maintenance in UK towns.

Is it getting enough solar irradiance?

Check whether your panel is getting enough sun irradiance. Its orientation should be between 25-45 degrees, which could vary geographically. If PV panels have a place perfectly facing towards sun irradiance, and you are still not yielding enough energy then it may be a shadowing factor or other factors affecting your output. You can take assistance from the Solar Pathfinder.

Temperature factor

If you have panels oriented in a perfect place where it gets enough solar irradiance, but still they aren’t yielding enough output power to energize your appliances, then there would bring problem. The above twenty-five (temperature in degrees Celsius), this can lead to Solar panel inverter problems too, so when mounting solar inverters, make sure to set up the proper airflow. However, solar inverters have their cooling system, to assure that it's operational.

Additional PV inverters Troubleshooting Solutions

- Check the fuse. If the solar inverter has an inbuilt fuse if it has blown, replace it with a new fuse.
- Check your breakers- one of the most common Solar panel inverter problems is that they trip the breaker if there is any fluctuation.
- Check for loose connections- wires can become open with time and when they heat up due to hot days. If they are loosely connected, it can cause Solar PV inverter efficiency problems.
- Maintain PV Panels- if panels are not maintained periodically, it can affect the efficiency and effectiveness of itself and the solar inverter too.
- Check the power supply. Ensure the solar inverter is plugged into an outlet with good power and is not damped.
- Check the inbuilt coolant system of the panel regularly. It should be operational.
- If the solar inverter is linked with the battery, check the battery's state of charge.
- Check the PV inverter's settings, and it can cause problems.

How Can Solar PV Inverter Problems Be Avoided in the Future?

- Check your equipment regularly.
- Be sure to have the proper voltage and amperage for your inverter. If the fuse is blown, then replace with the same amperage nominal value.
- Place surrounded by an PV inverter should be maintained regularly. And keep the PV inverter clean and free from dust regularly.
- Inspect your batteries every month or three.
- Keep a sight on your power consumption and educate yourself on solar energy and how it works.
- Search for the best solar system installers in your town.

Conclusion

As the name tag says, a solar inverter inverts the direct current (taken from PV arrays) to AC (a usable Current). Assured while purchasing, the inverter's regulated power should be greater than the rated regulated power of the battery bank. There are common Solar panel inverter problems like a blown fuse, trip breaker, loose connections, etc. However, Solar Panel Costing helps you in giving all information about the consultation, installation, Solar PV maintenance, and repair. Suppose you are searching for the most significant Solar inverter repair and maintenance services in the UK. In that case, you may collaborate with them since they provide the best Solar inverter consultation, repairing, and maintenance services in UK towns on both commercial and residential scales. Moreover, you can check that the Solar Panel Cost Calculator calculates the solar panel cost per your property size.
