Understanding Different Types of Solar Inverters

Not all solar systems are the same, and neither are their inverters. Choosing or maintaining the right type is important for performance and longevity. Here’s a look at the common types:

• String Inverters: This is the traditional and often most cost-effective option. Panels are wired together in “strings,” and each string connects to one central inverter. They are generally reliable for systems without significant shading issues.
• Microinverters: Installed directly on each solar panel, microinverters convert DC to AC at the panel level. This means if one panel is shaded or underperforming, it doesn’t significantly impact the output of other panels. They offer panel-level monitoring and are excellent for roofs with complex layouts or shading.
• Power Optimizers: These work in conjunction with a central string inverter. Like microinverters, optimizers are attached to individual panels, optimizing their output before sending the DC power to the main inverter. They provide panel-level optimization and monitoring while using a central inverter, often balancing the benefits of both string and microinverters.

Understanding the type of inverter you have (or need) is essential for effective maintenance, repair, or replacement.

Common Inverter Problems and What to Do

Solar inverters are complex electronic devices and can sometimes encounter issues. Some common problems include:

• Error Codes: Inverters often display codes indicating specific faults. Consult your inverter manual or contact a professional if codes persist.
• Reduced or No Power Output: This could be due to internal component failure, wiring issues, or external factors like grid problems.
• Overheating: Poor ventilation, direct sunlight exposure, or internal faults can cause overheating, leading to shutdowns or reduced performance. Ensure your inverter area is well-ventilated.
• System Disconnects: The inverter might disconnect from the grid or panels due to faults, grid instability, or safety reasons.

While simple checks like ensuring the inverter is powered on and ventilation is clear can be done by homeowners, most inverter issues require professional diagnosis and repair to ensure safety and maintain warranties.
