When to use microinverters?

There are many reasons to consider installing microinverters. For one, they allow for individual panel performancemonitoring, With microinverters, you can compare how each panel is performing on its own, rather than solelvevaluating the performance of the system alone. This can mean quicker servicing of equipment, as it's easier to identifv if a particular panel or microinwerter is failing.

Microinverters are also a good solution for more complicated installations that have panels facing differentdirections or are tilted at varving angles. lf vou have some panals facing east and others facing souith, usingmicroinvcrtcrs on cach pancl will allow them to pcrform to thcir maximum ability when sunlight hits them, as thcywill be notimpacted by the production issues other panels in the system might experience.

Pros and cons of microinverters?

Microinverters are useful in many solar installations, but also have their drawbacks. Here are some of themportant pros and cons of using microinverters to keep in mind.

What are microinverters and how do they work?

Microinverters are inverters installed right at the individual solar panel site, which differentiates them from centralized string inverters (where there's typically one inverter for the whole solar system). Most solar panel systems with microinverters include one microinverter per panel.

Because each microinverter operates independently of the other inverters in the system at the panel site, microinverters are classified as module-level power electronics (MLPEs). MLPEs are the best option for complicated installations or those with marginal shading.

With traditional string inverter technology, panels can only produce electricity at the level of the lowest-performing panel on the same string. This is not a problem with microinverters because each panel has its own inverter. Therefore, solar panels will continue to perform efficiently even if one panel in the system is not producing as much electricity as the others.

The size of each microinverter depends on the size of the panel and the amount of electricity it is capable of producing, as determined by your geography, the tilt, direction, and other factors. If your solar panel produces more electricity than its microinverter is able to convert at a given moment, "clipping" occurs, resulting in power losses.
