We have listed below five common problems with a solar inverter:
- Faulty installation of the inverters. A possibly obvious, yet very common problem with inverters is that they have been installed incorrectly. …
- Overheating. …
- Isolation Fault. …
- Inverter does not restart after a grid fault. …
- The MPPT module.
What causes solar to inverter failure?
A very common reason for failure in the solar inverter is due to faulty installation. If the solar panels are not matched with the inverter capacity, your inverter will not work efficiently. As a rule of thumb, your solar panel capacity should be up to 133% of the inverter capacity.
What happens when a solar inverter fails?
In any of the three events, your solar company will be able to either quickly fix the problem by, for instance, reconnecting your inverter to the internet, or work proactively with the manufacturer of the equipment to replace defective equipment.
How do you diagnose an inverter problem?
Connect the inverter to your battery and plug it in a controlled and limited power like a low voltage lamp. Now, use a voltmeter to get the reading of the inverter output and see if it works fine. If everything is okay, the machine should work perfectly, and the lamp should light up as well.
How often do solar inverters fail?
A study by kWh Analytics found that 80% of solar array failures occur at the inverter level.
Can solar inverters be fixed?
Electricians will tell you that they are often asked if they can repair solar inverters, and unfortunately, the answer is usually no – it is not possible to repair a solar inverter and, most of the time, the inverter will need to be sent back to the manufacturer for refurbishment or replacement.
What is the lifespan of a solar inverter?
While most solar power inverters come with a lifespan of approximately 5 to 10 years, they do require regular maintenance in order to ensure optimal solar PV inverter efficiency.
How do I know if my solar inverter is not working?
A simple health check is to look at the colour of the lights shining on the box during daylight hours when the system’s meant to be running. A green light on your inverter means your system is functioning properly. A red or orange light during daylight hours means there’s a system event or fault.
Do solar inverters break?
While solar panels can last 25 to 30 years or more, inverters generally have a shorter life, due to more rapidly aging components. A common source of failure in inverters is wear and weathering on the capacitors in the inverter.
Do inverters wear out?
The first reason for inverter failure is electro-mechanical wear on capacitors. Inverters rely on capacitors to provide a smooth power output at varying levels of current; however electrolytic capacitors have a limited lifespan and age faster than dry components. This in itself can be a cause of inverter failure.
Do solar inverters need maintenance?
Unlike a boiler, your solar panels should work efficiently without a yearly service. You shouldn’t need to pay extra costs for maintenance packages to keep them running well.
How much does it cost to replace a solar inverter?
Replacing a solar inverter costs an average of $2,200 with average prices for replacing string inverters ranging from $1,400 to $3,000 in the US for 2019, including the cost of labor. However, if you have a micro-inverter, that will only cost you about $350 to $750, including the cost of labor.
When should I replace my inverter?
If it’s determined that the inverter is the part no longer working, then it’s time to replace. If it’s out of warranty, you will have to purchase a new one.
Why is my solar not feeding into the grid?
If your solar system is not exporting electricity to the grid, it could be because of one or more of the following reasons. Remember, a lack of export does not necessarily mean your system has malfunctioned. You may be using more electricity during the day than your solar system is generating.
Can solar inverters overheat?
Inverters, like all semiconductor-based equipment, are sensitive to overheating and, in general, operate best at cooler temperatures, while suffering power losses and damage at higher internal temperatures.
Why is my solar inverter offline?
If the power station status of your Goodwe solar inverter is offline, it means that it is out of monitoring. This can happen in the night where there is no sun, a communication issue in the day time, or it can be an inverter issue. If it is a WiFi issue, you can try to do a reset or a reload.
How do I reset my solar inverter?

How do I reset my inverter?
Quote from the video:
Quote from Youtube video: Off turn it back. On. Now we went back to two solid green lights. If you don't hit at least thirteen three the inverter will not reset.
How do you reset an inverter after a power outage?
Switch off the DC isolator which should be located underneath the inverter. The screen should go blank, and the lights should go off. Leave it like this for 5 minutes or so, and then switch back on.
Why is my inverter not giving output?
Defective power switch
REASON: One of the most common reasons for inverter not working or not turning on is a defective power switch. SOLUTION: For this, you may need to unplug the inverter from the power source and plug in some other appliance into it. Turn on the appliance and see if it is working.
