As solar systems become increasingly prevalent for residential and commercial applications, it is critical to understand the associated issues. If you have seen a decline in energy production, it could be because of your inverter.
Inverters are the brains of solar systems, converting direct electricity from the panels into alternating current. This blog discusses solar inverter problems, causes, and potential solutions to ensure your inverters perform efficiently.
1. No Power Output
This happens when the solar inverter displays no power output, rendering your panels inactive. Possible causes include grid disconnections, inverter failures, or faulty wiring. If the solar inverters are loosely connected or if there is a possibility of a defective connection with the grid, power will be shut off for safety reasons. If solar inverters are not regularly maintained, they may shut down due to wear and tear.
Possible Solutions:
When the solar inverters are completely turned down, check for any loose or faulty grid connections. Check for error messages and read your manual for solar inverter troubleshooting instructions.
2. Low Power Output
Here are a few typical issues that can cause your solar inverter to function less efficiently and produce less power than it should. The most prevalent problem is shading, which occurs when neighbouring buildings, trees, plants, and creepers cast shadows on the solar panels. Dirt and debris can diminish the effectiveness of sunlight on panels. Other causes could include panel aging or common inverter issues, resulting in a drop in solar power output.
Possible Solutions:
Clear the barriers that impede the sunlight’s potential on a regular basis, trim the surrounding plants, and clean the debris with a gentle brush and water. If the problems continue for an extended period, replace the damaged parts and schedule maintenance.
3. Overheating
Since solar inverters are made up of electrical components, they may overheat during summer or in conditions with high temperatures. This results in reduced electricity output when the temperature hits its max operational temperature. Overheating happens when inverters do not disperse enough heat or when dust and debris clog the cooling mechanisms.
Possible Solutions:
Solar inverter solutions for overheating include inverters to be positioned in a well-ventilated environment, away from direct sunlight. In the summer, cooling equipment like fans can be used to ventilate the inverters. Before purchasing an inverter, make sure to check its cooling technique. Finally, clean the inverter’s vents on a regular basis to remove dust and dirt.
4. Isolation Faults
This is the most common solar inverter problem caused by a short circuit between several components of the inverter. In such circumstances, the inverter issues an “isolation alarm.” Moisture collection in the wires, poor wiring to the DC cables, or a faulty installation can all cause a short circuit. These isolation faults are predominant in moisture-prone locations like oceans or high-humidity zones.
Possible Solution:
When an isolation fault occurs, inverters either stop production or operate at a minimum production level. It is therefore critical to ensure that DC cables are of the supreme quality and installed accurately. On top of all, make sure that the inverter cabinet and inverter building are well protected.
5. Inverter Error Codes
Studies claim that about 20% of inverters face issues with error codes. Check the health of your inverters and look for a green light. If inverters display a bright green light, they should be perfectly fine. But, if the indicators show red or orange lights, then the inverters might be in trouble. One more evident indication is the display of error codes on the panel.
These error codes are usually triggered by voltage fluctuations, spikes, or surges. If there is any malfunction in the system, an immediate indication of an error code occurs on the display panel.
Possible Solution:
Understand the meaning of error messages and check your manuals for solar inverter troubleshooting steps. If the faults are due to software errors, look for instructions in your manual. Safeguard your system from any electrical issues and if the codes till persist, contact a technician for repair.
Conclusion
We have seen the possible causes of inverter failures and how to resolve them. Among them, isolation faults and short circuits can lead to serious accidents and damage. Therefore, regular maintenance is important as it not only enhances the longevity of the inverter but also helps in preventing any potential hazards.
