What is a Solar Inverter?
Simply put, a solar inverter is the brains of your solar energy system. It converts the DC electricity produced by your solar panels into usable AC power for your home or business. But inverters do more than just inversion. They also:
- Implement maximum power point tracking (MPPT): Ensuring you’re getting the most energy out of your panels.
- Monitor performance: Providing real-time system and panel-level data so you can track production and spot issues.
- Charge batteries (in hybrid models): Some inverters can also convert AC back to DC to store energy in batteries.
What Are The Types of Solar Inverters?
There are three main solar inverter designs on the market today:
- String Inverters - The classic setup—a central inverter box typically installed at ground level to handle inversion for the full solar array.
- Microinverters - Advanced panel-level inverters that convert DC to AC at each solar panel, offering advanced system monitoring and efficiency, especially for roofs with shading or varying tilt angles.
. - Power Optimizers - Small devices installed under each panel that condition DC power before sending it to a central string inverter. They combine panel-level optimization with the reliability of a string inverter.
Why Your Solar Inverter Matters
Your inverter isn’t just a piece of equipment—it’s a long-term investment. Making the right choice affects:
- How efficiently your system performs
- Your ability to track and troubleshoot problems
- The financial return on your solar system
Every solar inverter brand shares a lot of the same features and attributes. Price, reliability, efficiency, and product offering are, of course, among the factors that the Paradise Energy team examines when selecting the best solar inverter brands. However, there are three core things that we look at that differentiate and separate the top brands from the crowded inverter space.
Here are the three key factors the Paradise Energy team examines to identify the top solar inverter brands:
1. Monitoring Capabilities
We want to know what's happening with every system we install—without needing to send a crew out if something seems off. That’s why strong monitoring features are a must. Good monitoring allows both you and us to track your system's performance, spot any issues remotely, and even troubleshoot without rolling a truck.
2. Financial Stability of the Manufacturer
Solar inverters should last 10, 20, even 25 years. So, it’s crucial that the company behind your inverter is financially stable enough to honor warranties and provide support throughout that time.
Most of the companies on our list have faced financial challenges at some point—it’s not uncommon in the solar industry. While we closely monitor their financial performance, what concerns us most is when these struggles occur. If a company is struggling during a strong market, that's a significant red flag. On the other hand, financial difficulties during broader market downturns are less alarming.
3. Customer Support
Lastly, how well does the manufacturer support us—and ultimately you—as the customer? Do they offer solid technical resources? Do they help with troubleshooting and warranty claims?
These are the factors that separate good inverter brands from great ones.
