Best solar inverters of 2025

Your solar inverter is just as important as the solar panels you choose. While a few big-name brands still dominate the market, solar inverter technology continues to evolve, expanding your options.

Choosing the best solar inverter comes down to efficiency, voltage performance, warranties, and price. We looked at all these factors in dozens of models featured on the EnergySage Marketplace to determine the best inverters of 2025.

Five brands stood out: SolarEdge, Tigo, Enphase, Hoymiles, and Schneider Electric.

EnergySage equipment rating system

1. Best efficiency: SolarEdge Home Hub SE6000H

• Price: $2.90/W

• Efficiency: 99% CEC

• Warranty: 12 years

The SolarEdge Home Hub is the highest-rated solar inverter on the EnergySage Marketplace, thanks to its top-notch efficiency, solid voltage performance, and extended warranty. It’s a 10-kilowatt (kW) optimized string inverter that offers the best of both worlds: plenty of output power and panel-level optimization.

Unsurprisingly, that top-notch technology comes at a price. EnergySage data from the second half of 2024 shows that solar panel systems with this SolarEdge inverter cost $2.90 per watt (that includes the inverter and solar panels), making the Home Hub the most expensive inverter on our list.

2. Best voltage performance: Tigo EI Inverter TSI-7.6

• Price: $2.44/W

• Efficiency: 98.4% CEC

• Warranty: 12.7 years

The Tigo EI Inverter tops our list for voltage performance, maintaining efficiency throughout changing weather conditions. It’s also the second most efficient inverter of our top five picks, works as a hybrid inverter (so it’s great for both solar panel and battery systems), and delivers 7.6 kW of output power. 

While the EI Inverter is one of the most efficient inverters on the market, it’s not the most efficient—that title goes to SolarEdge.  Its 152-month warranty is also shorter than others in the market. 

3. Best warranty: Enphase IQ8+

• Price: $2.71/W

• Efficiency: 97% CEC

• Warranty: 25 years

Enphase is the most popular inverter on EnergySage by a landslide: More than 70% of quotes from the first half of 2024 included one. The first microinverter on our list, the IQ8+’s panel-level optimization and conversion can boost your system’s performance—especially if your home has a complex roof or shading. Plus, Enphase stands out with a 25-year warranty, the longest base warranty of any inverter on our list. 

Despite its huge market share, Enphase’s IQ8+ ranks fifth for voltage performance. Its 97% CEC efficiency is great by industry standards but falls short compared to the SolarEdge and Tigo inverters, which earned higher spots on our list than Enphase. 

4. 4-in-1 microinverter: Hoymiles HM-1500NT

• Price: $2.76/W

• Efficiency: 96.5% CEC

• Warranty: 25 years

The Hoymiles HM-1500NT 4-in-1 microinverter can simultaneously support up to four panels while maintaining panel-level optimization. Its 25-year warranty rivals Enphase as one of the best available, and its datasheet is competitive with the rest of our top picks. 

That said, Hoymiles is the least efficient inverter on our list. Although it performs well relative to the rest of the market, it isn’t a leader in any of the categories we evaluated. 

5. Best voltage performance: Schneider Electric 7.7 kW Inverter

• Price: $1.97/W 

• Efficiency: 97% CEC

• Warranty: 10 years

The Schneider Electric 7.7 kW Inverter may not be as popular as Enphase or SolarEdge, but it’s a great option if you’re looking for a hybrid inverter to support your solar panel and battery setup. It’s tied with Tigo for best voltage performance and is the most affordable inverter on our list. However, not all installers itemize hybrid inverters and batteries separately on their invoices, so don’t be surprised if you pay more than $1.97 per watt for your Schneider inverter and solar panels.

While Schneider is a solid option, it offers the shortest warranty term on our list with just 10 years of coverage. It also lacks panel-level optimization, so homeowners with shady roofs may want to skip this one.

There are three main types of solar inverters: string inverters, optimized string inverters, and microinverters. The best choice for your system mostly depends on your roof’s layout and conditions.

Module-level power electronics (MLPEs) like power optimizers and microinverters maximize electricity production, especially on complex roofs with shading issues. However, string inverters are often a great choice for simpler, unshaded roofs.

We evaluated dozens of inverter models quoted through the EnergySage Marketplace to determine which inverters are best. Here are some of the most significant factors we used to compare them:

Performance

Warranty

Inverters are the most likely component to fail in a solar panel system, so you want to ensure that your inverter has a comprehensive warranty if anything goes wrong.

Price

Given you only need one or two string inverters, they’re typically more affordable than microinverters—especially if you skip the power optimizers. Still, the more expensive inverter may be the most cost-effective in the long run.

We think the SolarEdge Home Hub is the best inverter overall, but that doesn't mean it's the best inverter for you. Some inverters are ideal for certain setups but won't work in others. Here are some questions to think about to find the best inverter for you:
