Fronius vs. Sungrow: Which Solar Inverter Reigns Supreme?

With the large role that inverters play in solar power systems, choosing the right solar inverter for your system is crucial. In Australia, Fronius and Sungrow are two of the biggest solar inverter brands to consider. To help you make an informed decision, we’ll compare these two products in terms of efficiency, durability, price, and warranty. 

Fronius Solar Inverter Review: Bringing Innovative Tech to Australian Homes 

As a solar company, Fronius needs no introduction when it comes to solar inverters. Its reputation for offering reputable products has also made it the more appealing choice for homeowners who prefer the lasting durability that Fronius’ premium inverters are known for. 

Fronius Solar Inverter Features

Fronius inverters employ features that maximise a solar system’s energy output and enhance overall performance. Here are key benefits you should know about: 

• Maximum Power Point Tracking (MPPT): Inverters with advanced MPPT provide maximum energy harvest. 
• Competitive Efficiency: With an efficiency rating reaching up to 98.2%, homeowners and businesses can rest assured that they can get the maximum return on investment. 
• Great Scalability: Inverters from Fronius are flexible and scalable so that when the time for expansion comes, it’ll be easy for homeowners to make upgrades. It also helps that Fronius inverters are lightweight and compact. 
• Smart Grid Ready: This feature is an important factor when future-proofing your solar PV system, preparing your system for the technical requirements of grids in the future. 
• Reliability and Durability: Fronius’ strongest feature, which also proves to be its most appealing one, is its durability. Adhering to strict European standards, Fronius inverters are built and designed using high quality materials that guarantee strength and resilience.
• Active Cooling Technology: On top of its IP65 rating, Fronius inverters are designed to retain remarkable performance and durability under high temperatures and challenging conditions.

Sungrow Solar Inverter Review: Affordable Alternative Without Compromising Quality

The rise in solar power installation can be attributed to the increasing affordability of essential solar components without compromising aspects of quality. Such is the case with Sungrow and its range of solar inverters, from a string inverter to microinverters. 

As a whole, Sungrow is a global brand best known for its cost-effective solar solutions. As of this writing, they’re the second largest inverter maker in the world, after Huawei inverters. From solar batteries to inverters, the company continues to evolve via advanced technology, helping make solar energy systems become more accessible. 

Sungrow Solar Inverter Features

Sungrow inverters are a popular choice in Australia because they provide high-quality options that don’t break the bank. Much like Fronius inverters, Sungrow’s products are also renowned for their high efficiency rates without the staggering upfront costs. 

Here are Sungrow’s remarkable features, ensuring you get the most out of your solar panels: 

• Industry-Leading Efficiency: Sungrow inverters offer competitive efficiency of up to 98.7%. 
• Flexible PV String Configurations: Flexibility in the configuration is important because you’ll be needing greater versatility in the design of solar power systems.
• High DC/AC Ratio: Sungrow inverters deliver a high DC/AC ratio of up to 1.3. A good inverter needs to have a DC/AC ratio of 1.25 and Sungrow products are able to top that, ensuring efficient energy conversion and optimal system performance.
• Wide MPPT Voltage Range: With a wide MPPT voltage range, your system can keep harvesting high energy yields from solar panels even when presented with challenging conditions like shading or fluctuations in temperature.  
• Smart Monitoring: With Sungrow’s iSolarCloud, customers can track their energy usage and their system’s performance using a user-friendly monitoring platform for real-time data. 
• Low-Noise Operation: Sungrow inverters are known to be quieter than Fronius inverters, a big plus for those who prefer their solar systems to produce less sounds. Between Goodwe and Fronius, the latter also produces more noise. 
• IP65/66 Ratings: Sungrow inverters are built to withstand external conditions, making them suitable for outdoor installations. 

Warranty Period: Sungrow vs Fronius

Both Fronius and Sungrow inverters offer a 10-year warranty, giving customers their needed peace of mind when investing in solar power. But while Fronius offers comprehensive coverage, including repairs and parts, you may require additional documentation for claims with a Sungrow warranty. 

In terms of warranty, Fronius has a slightly better reputation for hassle-free claims. Nonetheless, it’s worth noting that Sungrow’s growing presence in Australia means customer support is readily accessible. 

Durability and Performance: Sungrow vs Fronius

Here’s where it gets tricky — both Sungrow and Fronius solar inverters are reputable brands in terms of performance and durability. The former is durable enough to withstand harsh conditions, especially the newer models, while the latter is built for long-term reliability. Overall, Fronius has  a better track record when it comes to durability. 

As for their performance, Fronius inverters are known for delivering high efficiency rates, and so is Sungrow. The latter, however, impresses with a higher maximum efficiency, up to 98.8% in some models.  Fronius’ Active Cooling Technology, meanwhile, guarantees longer lifespan and consistent performance even under high temperatures.

Fronius vs Sungrow: Which is the More Affordable Option? 

Sungrow is clearly the more affordable option with prices ranging from $1,200 to $2,500, depending on capacity. You’ll have to spend more when opting for Fronius with prices typically ranging from $2,000 to $3,500 for a standard inverter.

Conclusion: Which One is Right for You? 

The answer to this question hinges on your specific needs, preference, and most importantly, budget. When considering the upfront costs, Sungrow is the clear choice being an affordable contender. It even boasts higher efficiency and lower noise levels. But if you prefer a solar inverter that’s globally positioned as a premium product, Fronius might be the right inverter for you. It’s designed and built to last for many years to come with a more promising track record for durability and high performance. Need more time and materials to make a decision?
