Choosing a rooftop solar system might be difficult because of the many alternatives available. Microinverters, a novel module-level power electronic (MLPE), have recently emerged as an alternative to string inverters for solar panels.

String inverters are often linked to a wall far from the array area, whereas microinverters may be attached to or mounted on individual solar panels behind the railing. Microinverters are attached to individual solar panels so that they can convert DC electricity to AC instantaneously.

Is Microinverter Better?

The advantages of micro-inverters outweigh the disadvantages of string inverters for homes that want to go solar. Microinverters have both benefits and downsides. So, let’s have a look at them-

Advantages Of Microinverters

Improved Performance:

Using a micro inverter, each solar panel may reach its full performance potential regardless of the weather, shading, or other external circumstances. A single solar panel can no longer negatively impact the solar array’s overall performance. A central inverter considers the whole set of solar panels as a single panel with the electrical attributes of the lowest-performing unit. The most-used power tools for electricians are saws and drills, including hammer/drills.

Extended Warranty

A central inverter is subjected to significant power and heat loads. Thus it’s only natural that you’ll need to replace your original inverter with a new one within the usual lifespan of your solar panels (20-25 years). Central inverter manufacturers often give a 5- to 10-year warranty, with the opportunity to purchase an extended warranty. It’s very uncommon for micro-inverters to provide warranties of between fifteen and twenty-five years, which better matches the life expectancy of your solar panels.

Increase In Flexibility

With a limited number of options, you may wind up with a central inverter that is considerably larger than you need. Inverters in the 3-6 kilowatt range are commonly available from foremost inverter manufacturers. When purchasing multiple central inverters, keep in mind that you may require a system with a bigger capacity.

Because you only need to purchase one micro-inverter for every solar panel you possess, this is not an issue with micro-inverters. Additionally, if your central inverter is tapped out, you may not be able to add more panel and micro-inverter combinations to your system in the future.

Enhanced Security

Enhanced security is a significant benefit of the project. There may be a lot of voltage in a line that connects a central inverter since the solar panels are wired together before they reach the central inverter. Two hundred forty volts is a significantly lower and safer voltage for micro-inverters to work at.

Disadvantages Of Microinverters

  • The Level Of Sophistication Of A Technology

There hasn’t been enough time for micro-inverters to accumulate long-term performance data. Due to their placement on the hottest part of the solar panel, there is a possibility of increasing failure after many years of heat exposure. A widespread recall of micro-inverters hasn’t occurred in the industry.

  • More Difficult To Maintain

The contractor must climb onto the roof and remove the solar panels if a micro-inverter malfunctions. On the other hand, central inverters are often installed near the main electrical supply, making maintenance and installation more straightforward.

  • Internet Access Is Required For Some Of The More Advanced Capabilities

Some of the most complex micro-inverter monitoring tools need an internet connection. Even if you don’t have internet connectivity, your solar PV system will still generate electricity. Still, you won’t be able to use some of the micro-inverter system’s benefits.
