The solar power generated by industrial and household use is the primary and most clean source of energy. But to keep the PV system in good working order the solar inverters are required to transform DC power into AC efficiently. So, when they work for an extended period, they could have some problems and also. We have reviewed some of the most common issues an inverter with solar power can encounter and solutions for them are explained as:
Inverter Not Turning On
The most frequent issue that an inverter for solar power faces is the issue that it doesn’t startup. One of the causes for this issue is
- Battery not connected
- An inverter that has been tripped
- The battery terminals are loose
- Charged battery
- Weak battery
- The terminals of batteries are reversed
Solution
There are numerous solutions to these diverse issues, which are described in the following article;
- The problem with the inverter that is tripped can be fixed with a reset of the inverter button or fixing the switch that powers it.
- In the event of discharged batteries, the only option can be replacing the battery with another one.
- If your battery is becoming weak, you should charge it for a couple of hours. It could be that it requires some recharging.
- The batteries’ terminals on the inverter, if they are loose or reversed, you can clamp them with a firm grip to check for corrosion and then clean the rust.
The battery fails to charge
A few reasons that batteries fail to charge solar power inverter is;
- Battery dead
- Burnt rectifiers
- Connectivity is loose.
- Fuses melted
Solution
These are the most prominent problems that cause batteries to fail to charge, and the only remedy is
- Replace the battery, if dead.
- Verify that the battery terminals on the inverter are corroded and then clean it.
Continuous Alarm Beeping
The constant alarm sound of a PV inverter could occur when the inverter is overloaded or the cooling fan in the inverter is blocked. The cooling fan in an inverter is its primary component; it must continue to run until the inverter operates. Because of an issue, if the cooling fan’s performance is not at the right temperature at which an inverter is required, the inverter will start sounding an alarm or shut off completely.
Solution
- If you notice the PV inverter emitting an alarming sound, shut off all devices that are connected to the inverter to ensure that there is nothing that could overload the inverter.
- Clean out the cooling fan in the inverter each month, so that it doesn’t cause any issues or cease working.
LCD Displays False Coding
The LCD screen of the PV inverter could display wrong codes on the display and this could be glitches. It could be because of two reasons: external or internal issues. External problems could be due to loose battery cables or wires. internal issues are typically related to circuits.

Solution
- The internal issues can only be resolved by a skilled technician Inverter should be taken to an in-house workshop in this instance.
- External problems can be solved at home, by checking the battery cables, or input/output wires.
- Sometimes, overload may be a cause for this. Therefore, take out every additional burden from the inverter, and review the inverter.
Inverter Making Noise
Power Inverters generate a lot of noise when they’re working. it’s more of the sound of wind due to the fan, which is normal. However, should you hear any sound coming from the inverter or its fan, then most likely debris or dust is accumulating within the fan.
Solution
- Remove all dirt and dust off the fan of the inverter to remove the noise or have it checked by an expert.
- If the sound isn’t making its way through, the fan requires replacement to resolve the issue.

Low Capacity for Backup
The inability to backup is among the main problems that an inverter is faced with. To avoid this issue, an inverter requires regular maintenance. One of the main causes for the shorter backup time in an inverter maybe
- Additional energy consumption
- Low electrolyte levels
- Low charge level
Solution
- To resolve the problem of excessive power consumption, you must disconnect the inverter from all devices for a while. Then, try putting less strain on the inverter and not be faced with the same issue.
- If the inverter you are using has lower electrolyte levels, then you should replenish it with distilled drinking water every week, to prevent low backup capacity. When you fill-up the inverter, make sure to keep the level of water within the minimum and maximum water limits.
- The issue of a low level of charge of an inverter could be quickly solved by putting the inverter’s solar panel on charge for a couple of hours.
Overheating
Electronic components are part of the manufacturing of solar power inverters. That’s their vulnerability to temperature. Temperatures that exceed their limits could result in a reduction in production. It can also cause production to cease if the temperature is above its limit. It could happen when your inverter’s cooling device isn’t operating properly or the inverter is causing too much load.
Solution
- To prevent overheating of the solar inverter, it is recommended to frequently examine the cooling and ventilation system of the inverter, that is, if it’s operating well.
- To prevent the escalating of temperature, wash the dust thoroughly from the inverter as well as its fan. get rid of the undergrowth that hinders the flow of air, etc.
Conclusion
This is a majority of the issues (mentioned previously) the solar power inverter may encounter. The solutions to these issues are provided and you can tackle these issues at home. If the inverter continues to malfunction, bring it to a repair shop or contact a specialist. If you’d like to purchase the top solar inverter available in Pakistan as well as a solar panel system you should make an outline of the qualities you’d like and search for an inverter with all of them. See whether it’s creating any problems and everything is working to ease your life.
