Solis vs Growatt Inverter 

Choosing the right solar inverter is one of the most important decisions when installing a solar power system. While solar panels generate electricity, the inverter is responsible for converting that energy into usable power for your home or business. Among the most trusted inverter brands globally, Solis and Growatt stand out for reliability, performance, and affordability.

Both brands have a strong presence in residential and commercial solar markets, but they serve slightly different needs. This detailed comparison will help you understand which inverter is better suited for your system.

Brand Background and Market Position

Solis is known worldwide for its strong focus on grid-connected solar inverters. It has built a solid reputation in commercial and industrial solar installations where stability, durability, and long-term operation are critical. Many large solar plants and commercial rooftops rely on Solis due to its consistent performance.

Growatt, on the other hand, has gained massive popularity in residential and hybrid solar systems. It is widely used for homes and small businesses because of its advanced features, battery compatibility, and user-friendly monitoring system. Growatt has positioned itself as a smart energy brand rather than just an inverter manufacturer.

Performance and Efficiency

When it comes to energy conversion, both Solis and Growatt perform exceptionally well.

Solis inverters are designed for stable power output and long-term reliability. Their efficiency is very high, allowing most of the solar energy produced by panels to be converted into usable electricity. This makes them ideal for grid-tied systems where consistent output is important.

Growatt inverters also deliver excellent efficiency and are optimized for residential usage. What makes Growatt stand out is its flexibility in handling variable solar conditions. Its advanced MPPT technology helps maximize energy production even when panels face shading or different orientations.

In real-world usage, the difference in energy production between Solis and Growatt is minimal, but Growatt offers better adaptability in complex rooftop installations.

Hybrid Capability and Battery Support

This is where the biggest difference between the two brands appears.

Solis is mainly designed for on-grid systems. While hybrid models exist, they are limited in availability and battery options. Solis is best suited for users who want to send power directly to the grid without relying on batteries.

Growatt, however, is widely recognized for its hybrid inverter technology. It supports a wide range of batteries and allows seamless switching between solar, battery, and grid power. This makes Growatt an excellent choice for:

• Homes with frequent power outages

• Users planning battery backup

• Net metering with battery storage

• Future expansion of solar systems

If battery backup is part of your plan, Growatt is clearly the stronger option.

Monitoring and Smart Features

Solis offers a clean and reliable monitoring system that provides essential data such as energy generation, system status, and fault alerts. It is simple and effective, especially for professional installers and commercial projects.

Growatt, however, provides a more advanced monitoring experience. Its mobile and web applications allow real-time tracking, remote control, energy consumption analysis, and system alerts. Users can easily monitor performance from anywhere, making it ideal for homeowners who want full visibility of their solar system.

In terms of smart features and ease of use, Growatt clearly leads.

Build Quality and Durability

Both brands are built to withstand harsh environmental conditions.

Solis inverters are known for their rugged construction and long lifespan. They perform well in hot climates and are commonly used in large-scale installations where durability is crucial.

Growatt inverters are also well-built, featuring modern designs, efficient cooling systems, and weather-resistant enclosures. While slightly lighter than Solis units, they are still highly reliable for residential and commercial use.

Solis may have a slight edge in industrial durability, but Growatt offers a better balance of strength and smart design.

Installation and Maintenance

Solis inverters are typically straightforward to install for trained technicians. Their setup is simple but less flexible in terms of configuration options.

Growatt inverters are easier for installers and users alike. Their software setup is more intuitive, and firmware updates can be done remotely. Maintenance is also simpler due to better system diagnostics.

For homeowners and small businesses, Growatt provides a more user-friendly experience.

Price and Value for Money

In most markets, Growatt is more affordable than Solis, especially in hybrid inverter categories. While Solis may cost slightly more, it justifies the price with long-term stability and industrial-grade performance.

Growatt offers better value for money for residential customers because it includes hybrid functionality, smart monitoring, and battery compatibility at a competitive price.

If budget and features matter most, Growatt is the better option.

Which One Should You Choose?

Choose Solis if:

• You want a strong grid-tied inverter

• Your system does not require battery backup

• You are installing a commercial or industrial system

• Long-term stability is your priority

Choose Growatt if:

• You want a hybrid inverter

• Battery backup is important

• You want smart monitoring and control

• You are installing a home or small business system

• You want better value for money

Final Verdict

Both Solis and Growatt are excellent inverter brands with strong global reputations. However, they serve different types of users.

Solis is best for large-scale, grid-connected systems where stability and durability matter most.

Growatt is the better choice for modern solar users who want flexibility, battery support, smart monitoring, and long-term savings.

Overall Winner for Most Users: Growatt
Because of its hybrid capability, smart features, and affordability, Growatt is the more versatile option for today’s solar installations.
