Solar Inverters

What Does a Solar Inverter Do?

Solar inverters are the heart of every solar energy system. While your solar panels collect sunlight and generate direct current (DC) electricity, it’s your inverter that transforms this power into usable alternating current (AC) electricity to energize your home or business. At Sundog Solar, we install inverters that provide clean, reliable power year-round, with smart features to protect your system and help you track performance.

Here’s how a solar inverter works:

  • Solar panels create DC electricity. Because your appliances and the grid use AC electricity, the inverter converts DC into AC power that can run everything from your lights to your refrigerator.

  • Modern inverters include intuitive monitoring tools, allowing you to see your system’s energy production, identify any issues, and understand how much power you’re generating at any time.

  • Your inverter ensures the electricity sent to the grid matches the right voltage and frequency. It also provides safety features, including automatic shutdown during a power outage (called anti-islanding), to protect utility workers and your property.

  • Advanced inverters can optimize energy harvest from each solar panel, especially on roofs with partial shading or complex layouts.

Trusted Solar Inverter Brands We Install

At Sundog Solar, we partner with some of the most respected inverter manufacturers in the industry—including SolarEdge, Enphase, and Tesla—to deliver exceptional performance, reliability, and long-term value. We also understand every home and business is unique: if you prefer a specific brand or technology, we’ll work with you to customize a solution that fits your goals.

Here are a few of the inverters we recommend:

  • Overview:
    SolarEdge systems use high-efficiency inverters paired with power optimizers to maximize production at the panel level, making them an excellent choice for Maine homes with variable shading.

    Key Benefits:
    Exceptional efficiency and reliability
    ⚪️ Advanced module-level monitoring
    ⚪️ Long warranties (often up to 25 years)
    ⚪️ Enhanced safety features

    Best For:
    Homeowners looking for a combination of strong performance, smart monitoring, and peace of mind.

  • Overview:
    Enphase pioneered microinverter technology, placing a small inverter behind each solar panel. This setup delivers the highest level of panel-by-panel performance tracking and resilience to shading.

    Key Benefits:
    ⚪️ Individual microinverters maximize output
    ⚪️ Robust warranties and durability in Maine’s climate
    ⚪️ Real-time, panel-level monitoring
    ⚪️ Easy expandability for future upgrades

    Best For:
    Homes with complex roof designs, partial shading, or owners who want detailed visibility into each panel’s production.

  • Overview:
    Tesla’s solar inverters integrate seamlessly with Tesla Powerwall batteries and solar systems, providing streamlined performance and app-based monitoring.

    Key Benefits:
    ⚪️ High conversion efficiency
    ⚪️ Full integration with Tesla Powerwall storage
    ⚪️ Simple, intuitive monitoring via the Tesla app
    ⚪️ Elegant, low-profile design

    Best For:
    Homeowners who are committed to the Tesla ecosystem or plan to combine solar with battery storage for energy independence.

How to Choose the Right Inverter

Selecting the right inverter is just as important as choosing the right solar panels. Here are a few factors to consider as you explore your options:

    • String Inverters – Best for roofs with consistent sun exposure. These are the most cost-effective choice but can lose efficiency if shading occurs on any panel in the string.

    • Microinverters – Installed behind each panel, microinverters excel in shaded conditions and deliver robust panel-level monitoring.

    • Power Optimizers – A hybrid approach combining string inverters with optimizers at each panel to improve output and visibility.

  • Look for inverters with high conversion efficiency (generally over 95%), so you capture as much solar energy as possible.

  • Choose inverters backed by strong warranties—most range from 10–25 years. Maine’s climate can be demanding, so investing in a dependable unit will provide long-term security.

  • Consider inverters that offer app-based or online monitoring so you can track production, see performance trends, and receive alerts if any issues arise.


  • While budget is always a factor, investing in a quality inverter with strong support and warranties often pays off through better efficiency and fewer maintenance headaches.
