Larry Beiler is the VP of Design & Procurement at Paradise Energy Solutions. With nearly 15 years of experience in the solar industry, Larry holds two NABCEP certifications and has played a key role in the design of many of our 2,000+ solar installations. He leads our team in carefully evaluating and selecting the top-performing equipment we install for both commercial and residential customers.
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:
There are three main solar inverter designs on the market today:
Your inverter isn’t just a piece of equipment—it’s a long-term investment. Making the right choice affects:
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.
Below are the six solar inverter brands we recommend and regularly install at Paradise Energy.
Where Enphase works best:
Ideal for smaller rooftop systems located near your interconnection point (where your system connects to the grid) - mostly residential.
