What Type Of Inverter Is Best For Uneven Terrain?

Choosing the Right Inverter for Uneven Terrain

When it comes to solar systems installed on uneven terrain, the choice of inverter is crucial. A string inverter is often preferred over a microinverter due to its ability to handle varying solar panel voltage inputs. This is because microinverters can become damaged if the voltage input exceeds their maximum rating, which can happen on uneven terrain where some panels may receive more sunlight than others.

Benefits of String Inverters in Uneven Terrain

String inverters can also provide a higher surge capacity, making them more suitable for systems with a varying load. This is particularly important in areas with high winds or where the solar array is subject to changing conditions. In addition, string inverters are often more cost-effective than microinverters, especially for larger solar arrays.

Comparison of String and Microinverters

While microinverters have their advantages, such as easier installation and monitoring, they are not the best choice for uneven terrain. In contrast, string inverters require a more complex installation process, but they offer greater flexibility and a higher level of reliability. When selecting a string inverter for an uneven terrain solar system, look for one with a high surge capacity, such as 10-20 kVA, and a wide input voltage range, such as 250-1000 VDC.
