Fronius vs GoodWe inverters - which one is best for you?

Fronius vs GoodWe inverters - which one is best for you?

15-20% of the entire cost of a solar system goes toward the solar inverter. GoodWe Inverter Price is considerably less expensive than Fronius Solar Inverter Price in terms of cost. The GoodWe inverter is about $800–$1000 more expensive than any decent Fronius inverter. However, GoodWe inverters often have a shorter lifespan than Fronius solar inverters. Additionally, Fronius inverters might be an excellent long-term investment.

Solar inverters are popular because of their low cost, high dependability, and high efficiency. However, there are a lot more factors to take into account when purchasing a solar inverter, such as:

1. Knowledge and Expertise.
2. The power range and inverter series.
3. Inverter Productivity.
4. Manufacturer's Guarantee

If you're reading this, you probably want to install a solar system or replace your current solar inverter but aren't sure which one is ideal for you. The distinctions are therefore briefly examined in this article.

Experience and expertise in the business

In 1945, Gunter Fronius established the Fronius in Austria. The business previously produced lithium-ion, lead-acid, and welding equipment. In 1992, the business later added solar inverters to its portfolio.

The Fronius Sunrise, the company's first solar inverter, was introduced in 1995. It assisted the business in becoming one of the world's top producers of inverters. Since then, Fronius has provided Australia's solar inverter market with top-notch products. At present, Fronius offers a broad power range from 3.0kW to 27.0kW.

Numerous certifications for quality, sustainability, and worker safety have been attained by Fronius. It consists of ISO 9001, ISO 9001:2015, and ISO 144001. More than 5400 experts are currently employed by the company's more than 20 offices around the world.

GoodWe is a well-known business that prioritizes research. They are renowned for producing energy storage systems and photovoltaic inverters. Since 2010, the business has been delivering solar inverters to the Australian market.

From 0.7kW to 250kW, GoodWe solar inverters are available. Both domestic and commercial uses are perfect for them. The business was one of the top 10 solar inverter manufacturers in the world in 2012. GoodWe recently received the esteemed VDE-AR-N5110-2018 compliance certificate in 2020.

More than 2000 people work for GoodWe across 15 different nations.

Power range and Inverter Series

Solar inverters from Fronius Solar Inverter come in four different series. Solar inverters from the Galvo and Primo lines are single-phase. In contrast, the Primo inverters lack a transformer while the Galvo inverters do. The three-phase transformerless solar inverter Symo and Eco are part of Fronius's most recent two series.

The Fronius Primo spans from 3.0kW to 8.2kW, while the Fronius Galvo solar inverters are less than 3kW. For a 6.6kW and an 11kW system, respectively, a Fronius 5kW and 8.2kW Primo solar system are perfect.

The Fronius three-phase solar inverters are the best option for anyone who needs a solar system for business needs. 3.0 to 20.0kW is Symo's power output range. For 13.3kW and 20kW systems, Symo 10.0kW and 15kW are the best options.

Fronius Eco is the final variety of Fronius solar inverter. Only 2 sizes—25.0kW and 27.0kW—are offered. For individuals who require a system with more than 30kW on a single inverter, this inverter is appropriate.

GoodWe offer solar inverters in eight different series, all of which are intended to reduce the price of electricity. The XS series, SDT G2 series, DNS series, Smart DT series, SMT series, MT Series, DSS series, and ET series is among them.

GoodWe XS series inverters have a single MPPT for their capacity. These inverters have a power range of 0.7 kW to 3.0 kW. With a power range of 3.0kW to 6.0kW, the GoodWe DNS series inverters incorporate a dual MPPT. The inverters in the GoodWe SDT G2 series have dual MPPT. The SDT G2 inverters' power output ranges from 4.0 kW to 10.0 kW.

The dual MPPT inverters from the GoodWe SDT series cover a large power range of 12kW, 15kW, 17kW, and 20kW. The GoodWe GW20KN-DT solar power inverter has a maximum efficiency of 98.6%.
The SMT series inverters are three-phase solar inverters. These inverters have 3-MPPT pathways designed for a specific setting. The SMT inverters have a power range of 25kW to 36kW.

Large-scale business rooftops frequently employ inverters from the GoodWe MT series. These inverters have four MPPTs. The GoodWe MT series has a power capacity of 50kW to 80kW.
Three-phase solar inverters are available in the SMT series. These inverters have 3-MPPT pathways designed for a specific setting. The SMT inverters have a power range of 25kW to 36kW. Use of the GoodWe MT series inverters on medium- to large-scale commercial rooftops is common. There are four MPPT inverters. The GoodWe MT series has a power range of 50kW to 80kW.

The first single-phase on-grid inverter, the DSS series is compatible with double-glass bifacial modules. DSS series inverters have a power capacity ranging from 3.6kW to 5.0kW. The GoodWe ET series solar inverters are three-phase energy storage inverters with power ratings of 5kW, 8kW, and 10kW. There are 2 MPPT systems in these inverters.

Inverter Effectiveness

Fronius inverters have a residential efficiency of up to 95 to 98%. The GoodWe inverters, on the other hand, produce up to 96.5 to 98.3% efficiency. Inverters from the Fronius Galvo series have an efficiency range of 95.8 to 96%. The least efficient Galvo is 1.5kW, with a 95.8% efficiency. Fronius Primo and Symo, on the other hand, have efficiency rates of 97.9% and 98%, respectively. The maximum efficiency, at 98.3%, belongs to the Fronius Eco series.

The NS series 1kW solar inverter from GoodWe has the lowest efficiency, yet it still achieves a maximum efficiency of 96.5%. Aside from this, all GoodWe inverters have an efficiency of at least 97%. The GoodWe SDT series 10kW, 3-phase, dual MPTT string inverter is your best option if you require a more efficient inverter, nevertheless. The most effective inverter, with an efficiency of 98.3%.

The Producer's Warranty

A solar inverter has a 10–20 year lifespan. Any high-quality solar inverter must have a minimum 10-year lifespan. So, to protect the long life of your inverter, look into warranty alternatives. All manufacturers provide a 2- to 5-year limited warranty on their equipment. However, look into warranty extension possibilities if you want your solar inverter to endure a long time.
Good, We provide a 5-year limited guarantee on all of its solar inverters. A variety of warranty extension options are available from GoodWe. Up to 7, 10, 5+2, 5+5, 5+7, 5+10, 5+15, and 5+20 years can be added to the warranty. Make sure you purchase the inverter from a recognized source of supply.

Speaking about Fronius, they provide a 2-year warranty on all of their goods. The warranty can be extended at no additional charge for up to seven years. Simply register your solar inverter online at Fronius Solar. web to get started. You can purchase an extended warranty for up to 20 years if you'd like greater security.


I hope this essay has clarified the distinctions between GoodWe and Fronius solar inverters. The ideal solar inverter for you will depend on your demands, even though Fronius and GoodWe are both leading manufacturers.
