When one or more inverters fail, multiple PV arrays are disconnected from the grid, significantly reducing the project’s profitability. For example, consider a 250-megawatt (MW) solar project, a single 4 MW central inverter failure can lead to a loss of up to 25 MWh/day, or $1250 a day for a power purchase agreement (PPA) rate of $50/MWh.
Possible Causes. Power Surges: Sudden increases in voltage can damage the memory integrity. Age: Over time, EEPROM can degrade, losing its ability to retain data. Quality Issues: Lower quality components may fail prematurely under normal operating conditions.
An inverter must be able to restart itself after a grid fault (if there are no other faults). For example, voltage peaks which occur during sudden deactivation could trigger cut-outs in the system. If the inverter does not restart itself, a service team will then have to come on site in order to restart the system.
Solar inverter failure can mean a solar system that is no longer functioning. Of course, the first step when that happens is to determine what has caused the system to fail. However, it’s also important to know how you can protect the system from future failure. Check out these 6 causes of solar inverter problems and how to prevent them.

6 FAQs about [Reasons for photovoltaic inverter deactivation]
What does a solar inverter failure mean?
Solar inverter failure can mean a solar system that is no longer functioning. Of course, the first step when that happens is to determine what has caused the system to fail. However, it’s also important to know how you can protect the system from future failure. Check out these 6 causes of solar inverter problems and how to prevent them.
What happens if a solar panel inverter fails?
As the inverter is responsible for converting the DC power from the solar panels into usable AC power, a malfunctioning or non-operational inverter can hinder the energy flow, leading to lower electricity generation. System Shutdown: Inverter failures can sometimes cause the solar panel system to shut down completely.
What should I do if my solar inverter fails?
If you suspect an inverter failure in your solar panel system, it is important to take immediate action to minimize downtime and address the issue. Here are some steps to follow when your inverter fails: Contact Your Solar Installer: Contact your solar installer or a qualified professional who can assess and diagnose the inverter problem.
Why do solar inverters shut down?
Grid instability: Rapid fluctuations in grid power can trigger an inverter shutdown to protect your system from any potential damage. Safety protocols: Inverters are designed to shut down in the event of any abnormalities, including a power outage, to protect your solar system.
What are some common problems associated with solar inverters?
Some common problems associated with solar inverters include: Component Failure: Inverters consist of several electronic components, such as capacitors, transformers, and semiconductor devices, that may degrade or fail due to aging, excessive heat, or manufacturing defects.
Can overvoltage-induced inverter disconnections prevent solar power losses?
Scientists at the University of South Australia have identified a series of strategies that can be implemented to prevent solar power losses when overvoltage-induced inverter disconnections occur, due to voltage limit violations.
