Keeping up with a home solar system is quite low maintenance, but you should clean the panels and check the batteries periodically. The inverter, on the other hand, is the system’s weakest link. So, make sure you install it correctly and learn how to keep it clean and in good condition.
Tips for Installing and Maintaining Solar Inverters
The ideal environment for an inverter is a dry, dark, and ventilated area.
Microinverters can start converting DC to AC the moment they are connected to solar panels. Since string, central, and hybrid inverters are independent devices, their placement is of the utmost importance. While inverters do not absorb sunlight, solar panels do. Ideally, you should store it somewhere dry and airy. Perfectly situated in a garage. Keep all heat- or fire-generating objects away from the area. According to certain manufacturers, inverters need at least twelve inches of clearance for proper air circulation.
When installing power inverters, especially when linking them to the grid, it is best to leave the task to experts. To ensure proper connection of your inverter to the commercial grid, contact your local power company beforehand.
Find out what your system needs before you buy an inverter.
Before you purchase the inverter, make sure it is compatible with your system. You can measure the inverter’s capabilities in watts. The ideal situation would be for your inverter’s DC rating to be at least as high as your solar array.
It is necessary to use an inverter that is approximately 7 kW, give or take a few percentage points, while installing a 7 kW solar PV system, for example. Size recommendations for appropriate array capacities are usually included in product specification sheets for inverters.
When a solar array’s DC rating is more than 50% higher than the inverter’s capabilities, a phenomenon called “clipping” happens and overall power losses occur because the inverter limits the incoming energy.
Be very careful while looking for inverters you can learn more about this by researching and getting insight on how to connect solar panel to inverter.
Regularly remove dust and debris from the air filters.
The inverter can be set to operate automatically once the installation is finished. Still, it could use some TLC occasionally. Keep in mind these essentials to ensure your solar panel inverter continues to function at peak efficiency:
- Just like any other complex electrical device, the inverter is sensitive to dust and heat; therefore, it is recommended that you wipe it out periodically. The frequency with which this is necessary will depend on your location and the airborne dust levels. Annually might be more than enough.
- The air intake filters of inverters become dusty with time. They must be cleaned, but a professional is the way to go. The internal fan of an inverter is essential for its cooling. Please ensure that it works.
- Make sure all the connections are firmly attached.
- The state of most inverters may be easily monitored by looking at their screens. If an error code is shown, contact the manufacturer for assistance. They might be able to figure it out.
Maintaining microinverters is a breeze. Manufacturers advise visually evaluating the modules after storms or big hail, and they also recommend having a professional check them once a year.
Conclusion
Solar panel inverters, whether string, central, or hybrid, typically come with manufacturer warranties that cover 10–15 years. Alternatively, microinverters are built to last for a minimum of 25 years, which is the average lifespan of solar panels. With proper installation and maintenance, you can avoid emergencies and delay purchasing a new inverter.
