Growatt Inverter Review | Excellent Efficiency And Performance!

My solar inverter is the heart of my solar system, considering it’s where DC electricity turns to AC. Accordingly, it’s of great importance to select the best quality model.

Growatt inverters, a brainchild of the China-based Growatt New Energy Technology, is among the most reliable solar companies based on my experience and comprehensive tests.

This Growatt inverter review will take you through the crucial aspects of this global brand (see also Jupiter inverters), including its outstanding features and the most notable models. You’ll also learn the most important considerations when looking for the best solar inverter.

Growatt Inverter Review: A Brief Overview of Solar Inverters

Growatt inverter on the wall

At its core, a solar inverter turns sunlight trapped in the solar panel into the electricity that powers our homes.

It transforms the DC output (or variable direct current) produced by solar panels into 120V/240V AC (or alternating current) output. All our home appliances use alternating current, not direct current. 

Currently, the market is flooded with many options, making it hard to choose the perfect product. Focusing on a reputable brand like Growatt can simplify the search for you, as you will discover in the next sections. 

Is Growatt a Good Brand?

You might wonder why I’m placing Growatt above the numerous notable power inverters for solar systems.

First, the inverter manufacturer is a smart energy solution enterprise. Their dedication to the craft is evident in their firm quality control system, maximum power point tracking, and colossal investments in research and development. 

Moreover, the company’s over 400 engineers are dedicated to perfection and have managed to deliver up to 98% efficiency. Finally, the products are among the most affordable in the solar industry.

So, YES! Growatt is an excellent brand.

Where Is the Growatt Inverter Manufactured?

Like almost every solar system component I’ve used, from PV modules to solar inverters, to batteries, Growatt solar inverters are made in China, a country with immense skilled labor. That’s why it’s relatively affordable. I’m sure you can’t resist a top-notch solar inverter at a competitive price.

The company also has offices across the globe, including in Germany, the USA, Australia, and the United Kingdom. 

Growatt Inverter Efficiency and Performance

The company has been in business since 2010, but it’s established its presence. Its success can be attributed to what most customers call “technological miracles” like the highly efficient TL-HX, Max, and many more series of inverters.

Some of their inverter models have impressive overall performance and efficiency rates of up to 98%, which is laudable. The company has sold more than 1.7 million inverters across more than a hundred nations worldwide.

Growatt Inverter Solar System Monitoring 

Growatt does well in terms of system monitoring. I can quickly turn on remote monitoring to receive real-time updates and insights like export, self-consumption, and power input through the dedicated mobile app or website. The Wi-Fi dongle’s reach is slightly beyond 50 meters.

After linking your dongle to Wi-Fi, I installed the ShinePhone iOS app (there’s an Android version, too), filled out a few details, and scanned the barcode on the dongle. Moreover, the inverter itself has a screen for physical monitoring.

Point of Difference

Growatt manufactures diverse single and three-phase inverters that use maximum power point monitoring (MMPT). These devices are CEC-approved, hence rank high in terms of reliability. They also don’t have a transformer, which makes them one of the most efficient in the market.

Technical points and numbers aside, the inverter manufacturer has addressed every detail regarding the Growatt solar inverter design. The machines aren’t just sleek, but are also equipped with touch OLED displays. It’s so easy; even my grandma can operate it. Lastly, you get value because the machines are pretty affordable.

Growatt Inverter Warranty Period

Growatt offers a five-year warranty period that’s extendable up to a decade. But eligibility for this extension varies across models and markets.

Important Considerations When Choosing a Solar Inverter

Knowing the elements to consider can simplify your search for the right product. Here are the key factors to have in mind as you shop around:

Solar Inverter Efficiency

It is the ratio of Growatt solar inverter’s output to input power under specific conditions. Currently, the nominal efficiency ranges between 80% – 95%. But Growatt inverter models can surpass these limits.  


You need a power inverter that fits your budget. So when looking for the best solar inverters, consider an affordable product that offers value for your money.

Rated Output Frequency

Extreme output frequency can cause power tools with motors (like refrigerators and washing machines) to heat up and reduce efficiency. So look for a stable output frequency value of about 50Hz (with less than 1% deviation).


Under normal circumstances, a solar inverter should not exceed 80dB of noise, while a small-scale model shouldn’t exceed 65Db.

Protection Measures

The best inverters offer complete protective measures to handle abnormal situations like:

  • Input over-voltage and under-voltage
  • Over-current
  • Output short-circuit
  • Input converse-connection
  • High ambient temperatures
  • Lightning

Growatt Inverters: The Good and Bad at a Glance

These devices have several pros and cons. 


Setbacks but Not Deal Breakers

  • User friendly 
  • Affordable 
  • Easy to assemble
  • OHSAS18001, ISO9001, and ISO14001-certified
  • Highly efficient
  • One or two MPPTs
  • Clean Energy Council-approved
  • Relatively less noisy
  • Impressive European efficiency rates
  • Has both string inverters and hybrid inverters
  • Being manufactured in China isn’t necessarily a valid setback, but Chinese brands face discrimination based on this. It isn’t logical, but it harms the brand’s reputation. 
  • Growatt is a relatively new company and has yet to gain much popularity as its rivals. But the manufacturer makes up for it with impeccable research and development.
