Pros & Cons of Solar Microinverters

If you’re considering installing solar panels on your home, one of the most important decisions you’ll need to make is whether to use a string inverter or solar microinverters to ensure you’re getting the most out of your solar system.

Here at Trione Energy, we have extensive experience installing both types of systems. In this article, we’ll explore some of the key pros and cons of solar microinverters to help you determine if they are the right choice for your property

What are Solar Microinverters?

Microinverters perform the same function as traditional string inverters by converting the direct current (DC) electricity generated by solar panels into alternating current (AC) that can power your home. The key difference is that microinverters are installed at the back of each individual solar panel, rather than in a central string inverter located elsewhere. Enphase is the world leader in microinverter technology and the brand we recommend and install at Trione Energy.

Pros of Solar Microinverters For Melbourne Homes

Maximum Energy Production: Each Enphase microinverter optimizes the output of its solar panel by maximizing voltage and adjusting to changing conditions independently of other panels. This means all panels can perform at their peak even if partially shaded.

Monitoring and Diagnostics: The Enphase Envoy communication device provides panel-level monitoring so you can view each panel’s performance and be alerted to any issues. This makes troubleshooting very easy for an electrician.

Future Proofing: Microinverters are easily upgraded since panels can be added almost anywhere on your roof. They also have a 25-year lifespan matching the panels themselves.

Safety: Enphase microinverters meet stringent safety and installation standards with built-in rapid shutdown capabilities.

Microinverters are the perfect option for people with partially shaded roofs or in areas with low light, ensuring you can still get the most out of your solar investment.

Cons of Solar Microinverters

Higher Upfront Cost: While paying for themselves in increased energy production over time, microinverters do have a higher upfront equipment cost than string inverters alone. However, the increase ‘bang for your buck’ over time warrants this cost in the majority of cases.

More Components: Each panel has its own microinverter plus the communication device, increasing potential points of failure over a single central inverter.

Harder To Troubleshoot: If a microinverter fails, an electrician needs to access the individual panel, diagnose which unit failed, and replace it. While this can make things a little more complicated, a skilled solar electrician should have no issue finding the fault and carrying out any repairs or replacements.

Is a Solar Microinverter System Right For You?

Here are the key factors to consider when deciding:

  • Roof complexity: Microinverters excel for roofs with many angles or partial shading and allow flexible panel placements.
  • Monitoring needs: Their monitoring capabilities are worth it if you want panel-level performance data and alerts.
  • Lifetime savings: Their increased energy yields over 25+ years far outweigh the higher upfront costs.
  • Reliability: High-quality microinverters like those from industry-leader Enphase have low failure rates.

At Trione Energy, we recommend microinverters for their future-proofing and maximum energy generation abilities, especially when combined with Enphase’s track record of quality and reliability.
