Sungrow Inverter Vs Fronius Pros and Cons

So, what are the Sungrow inverter vs Fronius pros and cons? The Austrian company Fronius, which was founded in the 1940s, has been producing solar converters for many years. Sungrow is the world’s second-largest producer of solar inverters, just after Huawei. They are offered by a lot of bill-buster businesses as their top inverter. So, let us check out Sungrow inverter vs Fronius pros and cons.

Fronius Pros:

  • Reliability: Problems with a Fronius transformer are extremely uncommon. This is the result of both their meticulous quality control and superb design, which includes active cooling.
  • Flexibility: Two MPPTs are available for the Primo 5 (5kW single-phase inverter), enabling two parallel strings into each (i.e. four strings total). This enables much more flexible configurations than the typical 5kW inverter, which only has a single MPPT or even two MPPTs with only a single string in each.

Fronius Cons:

  • Noise: Inverters from Fronius have active ventilation (i.e. a fan). Although it makes them louder than other inverters, this keeps the inverter cooler and increases its lifespan.
  • Commercial inverters: Their biggest inverter right now only produces 27kW, while others can produce 110kW+. A 50kW and 100kW inverter from Fronius will be available, but they’re not very adaptable.
  • Price: This luxury inverter has a premium price to match its premium quality. Having said that, the inverter would be part of your PV installation that you should splurge on.

Sungrow Pros:

  • Quality: Sungrow’s construction quality is outstanding, though not quite at the level of Fronius. Many Sungrow inverters have been installed, and very few problems have been encountered.
  • Models available: Sungrow can meet any need, whether it is for 1kW to 110kW, single phase or three phases, hybrid or not.
  • Price: They are extremely competitively priced and are less expensive than those manufactured in Europe.

Sungrow Cons:

  • Chinese: Some people believe that products marked Made in China are inferior. Chinese brand Sungrow is far superior to other Chinese namesakes.
