Understanding Solar Inverters
e that converts the direct current (DC) electricity produced by solar panels into alternating current (AC) electricity that can be used to power your home’s appliances, lighting, and other electronics. (For a condensed explanation, see Explain Like I’m Five: Solar Inverter)
If your inverter fails, your residence will no longer receive the electricity generated by your solar panels. This means that you could wind up with an unexpectedly high electricity bill because you unknowingly drew power from the utility grid.
So how can you prevent problems with your solar inverter? What steps should you take if you require solar inverter maintenance or repair? This guide will teach you the essentials of solar inverter maintenance, repair, and service, as well as the significance of the inverter to your solar power system.
Why would my solar power inverter malfunction or break?
While solar panels are designed to last at least 25 years, solar inverters are typically more complex and have a reduced expected lifespan. Even the finest inverters have a 10- to 12-year warranty, so you will likely have to replace the inverter twice over the lifetime of your solar power system.
If you suspect that your inverter is malfunctioning, search for the following signs:
Unusually High Electricity Bill – If your inverter isn’t producing enough energy for your residence, you’ll be drawing more power from the grid than usual, causing your utility bill to rise.
On-Screen Error Message – An error message is a reliable indicator that something has gone awry. Consult with a certified solar technician to determine the cause of the problem and how to correct it.
No Status Lights On – If there are no status lights on, or if the light is yellow, red, or flickering, your inverter most likely has a problem.
Some solar batteries are charged by AC power from the inverter, so if your battery isn’t charging, it could indicate that your inverter isn’t functioning correctly.
If your inverter does not appear to be connected to anything, or if the connection appears to be broken, this may be a sign that the inverter needs to be repaired.
There are a few common issues that could cause your inverter to malfunction:
Solar Inverter Heating Up
It is normal for your inverter to become relatively warm during use, but it can become dangerously heated. If the inverter overheats, electricity production will decrease significantly, or it will cease functioning entirely.
During installation, solar technicians will typically evaluate your inverter to ensure that the cooling technology functions correctly. This includes inspecting the ventilation of the building containing the inverter and the switch cabinet.
Once installed, the inverter can be inspected periodically to ensure that the cooling system and ventilation continue to function properly. Additionally, you can reduce the risk of overheating by cleaning dust filters and removing obstructions that could obstruct ventilation.
Solar Inverter Installation Error
Even professionals can commit errors. Yes, it is possible that your solar technician did not install the inverter properly, either in terms of physical connection or programming.
The solar installer must adhere to the documentation provided by the inverter’s manufacturer to ensure a successful installation. After installing the inverter, the installer must conduct several tests, including a yield test, remote activation, remote deactivation, and reactive power regulation. Any problems with the connection should be apparent during testing and resolved immediately.
Faulty Inverter Isolation
Another potential inverter issue is the isolation defect, which is a short circuit between circuit components that generates a “isolation alarm.” In the event of this error, the inverter will either operate at a reduced capacity or close down entirely.
This alarm can be caused by a combination of factors, including damage to the cable jacket, moisture, improper installation, and a poor connection of DC cables to the panel. This problem is more prevalent in areas with higher humidity, such as coastal regions.
Maximum Power Point Monitoring Problems
Numerous inverters utilize Maximum Power Point Tracking (MPPT), a performance-optimizing technique. MPPT occurs when photovoltaic (PV) modules in a solar array are coupled to the inverter in series known as “strings.”
Each string generates various amounts of energy based on shading, panel placement, panel defects, etc. Due to these conditions surrounding the inverter, the strings can simultaneously send various voltages to the inverter.
The MPPT module ensures that your system always utilizes the optimal supply voltage, allowing your panels to generate the maximum amount of electricity. However, this MPPT system is prone to malfunctions, which would necessitate professional repair of your solar string inverters.
Problems with Solar Power Inverter Restarting
Typically, an inverter can resume itself if a disruption to the broader electricity grid renders your solar power system inoperable. A service team or installer must manually restore the system if this does not occur. Your solar panels will not produce electricity until they are removed.
To avoid this issue, you should purchase a system with high-quality components and a monitoring system that operates around the clock. (Just like the solar power systems offered by Palmetto.) Thus, as soon as an issue arises, someone can be dispatched promptly to resolve it.
Tips for Your Solar Maintenance
Despite the fact that a solar power system is designed to be reliable and low-maintenance, there are a few steps you can take to ensure peak performance from your equipment. Here are a few tips for solar inverter maintenance to maintain your inverter functioning properly:
Maintain The Inverter’s Temperature
As your inverter converts DC to AC, it naturally generates heat. To ensure the inverter receives adequate ventilation, you should leave at least 12 inches of space around your equipment.
If your inverter has a fan, ensure that nothing obstructs or could be drawn into it. The inverter could overheat and lose efficacy if the fan fails to operate.
Lastly, ensure that there is nothing combustible near your inverter, as it could catch fire if the equipment becomes too heated.
Maintain A Clean Air Intake Filter
Depending on the location of your inverter’s air intake filter, it may become clogged over time. If the filter collects an excessive amount of dust and debris, it will not be able to cool as effectively, which will reduce the inverter’s efficacy.
We recommend calling a professional to clean the filter if it becomes soiled, as you may need to disassemble some equipment.
Examine for Error Codes
Although it is not necessary to check your inverter daily, you should do so periodically to ensure that everything is operating as anticipated. This includes inspecting the inverter’s display for error codes or a light that is not typical. If something seems awry, contact a professional for an evaluation.
Utilize Solar Observation Technology
If the manufacturer of your solar power system provides monitoring technology such as a smartphone app, you should utilize it. This solar technician can provide you with regular updates on the status of your solar panels and inverter, as well as prompt access to customer service and technicians, should you require them.
Keep in mind, however, that all technology can occasionally malfunction, so it’s still a good idea to visually inspect the inverter on a regular basis.
What Must I Do If My Solar Inverter Fails to Function?
Unfortunately, regardless of how well you maintain your inverter, it is still susceptible to performance-reducing issues. If your inverter stops functioning, you have multiple options for fixing the issue.
Contact Your Solar Installation Service Provider
Consult with the company that installed your solar panel system as a first step. They may be able to dispatch a technician to evaluate your inverter’s condition. They should also possess the manuals and technical knowledge necessary to either repair or replace the inverter.
Contact the manufacturer of the solar inverter
Contact the inverter manufacturer if the solar company that installed your inverter has ceased operations. This company may be able to dispatch a technician to examine your inverter and identify the issue. They may also request that a local solar company dispatch someone to repair or replace your inverter on their behalf.
Contact A Reputable And Established Solar Company
You may also contact an established and reputable solar company in your area, such as Palmetto. At Palmetto, we can dispatch a technician to diagnose your inverter’s problems and assist with its repair or replacement.
If feasible, you should provide the solar maintenance company with any paperwork or information from the installers to expedite the process of determining the problem.
Can I Self-Repair My Solar Inverter?
No. Never attempt to repair an inverter on your own. It is a complicated piece of technology that requires a great deal of technical knowledge; if you attempt to repair it, you may make the problem worse or injure yourself.
In addition to making the problem worse or injuring yourself, attempting to repair the inverter yourself could void the maintenance and service contract for the entire solar system. In addition, if you are not a licensed solar technician, your utility company and other government entities may penalize you.
If you observe that something seems amiss with your inverter, it is best to seek professional assistance. They should be able to quickly identify the issue and repair or replace the inverter as necessary.
