Huawei is a Chinese company that provides information and communication technology, smart devices, and solar products. The company offers inverters that are battery-ready, cost-effective, and efficient. It also offers Smart Energy Storage System SUN2000-450W-P optimisers and the FusionSolarApp. 

Huawei is mainly known for its telecommunication devices, but it also produces solar products.

If you’re interested in learning whether Huawei is an excellent solar brand, this article is for you. 

This article will help you learn what Huawei is and whether it’s a good brand. You will also know about different Huawei products and where to buy them.

Let’s dive in!

Who is Huawei?

Huawei is a Chinese company founded in 1987 that provides information and communication technology smart devices globally. The company’s headquarters are in Shenzhen, Guangdong, but it has a presence in over 170 countries with over 180,000 workers.

Huawei also manufactures solar products. The company is the largest manufacturer of inverters worldwide, but they are more concentrated on telecommunication devices. 

Huawei started manufacturing an efficient and lightweight residential solar inverter in 2018. In 2020, they started selling 2nd generation residential hybrid inverters, a compact optimiser and different types of 3-phase inverters

FusionSolar Huawei products focus on energy management systems and smart inverters. FusionSolar covers industrial, commercial, residential and utility-scale projects. The Smart Energy Controllers are created from single-phase and 3-phase installation. 

Let’s look at Huawei’s FusionSolar system

Fusion Solar is Huawei’s energy management system which aims for one size fits all management purposes. The management system is a cloud-based monitoring portal with many monitoring and data logging features and an easy to read interface. 

You can use the Fusion Home mobile app for direct connection and monitoring via Local WIFI and inverter setup. The monitoring portal is easy to read and understand with a modern user interface. 

The Fusion Home is for the Sun2000L inverter that comes in different kW sizes(2.0, 3.0. 4.0, 4.6 and 5.0). It has an integrated energy storage interface where an inverter doesn’t need batteries to function, which is a great feature. 

Where are Huawei solar products made?

Huawei is a Chinese based organisation, and most of its solar products are manufactured in China. 

Is Huawei a good brand?

The Huawei Company is a good brand with next-gen inverters that offer many advanced features. These inverters make life easier and more convenient, but they also have drawbacks.

Benefits of Huawei inverters

  • Cost-effective: Huawei solar products have become popular in Australia due to their affordability.
  • Battery-ready: Huawei inverters are battery ready, and they have an interface that you can use with LG Chem RESUH battery. The built-in battery offers optimum performance. 
  • Efficient: The Huawei inverter is 99% effective or even more than other inverters. 
  • 5-year warranty: Huawei offers a warranty that allows you to replace the solar products within five years completely, plus another 5-year warranty that can be bought. The warranty means that you can replace parts or inverters for free, but you will cater to labour charges. 

Cons of Huawei inverters

Huawei’s manuals say that their inverters should be installed 500m away from the coastline (salty areas). Most Australian buildings are within the 500m mark from the coastline; hence most people can’t use the Huawei services. It will be hard to claim your warranty if you install the inverters within 500m from the coastline. 

Which inverter is better: Fronius or Huawei?

Huawei is better than Fronius overall. However, Fronius is better if you have frequent grid failures. 

To determine which inverter is better between Fronius and Huawei, you have to look at the following factors:

  • Reliability: Huawei solar inverter is battery ready and has low limitations making it better than Fronius.
  • Hybrid battery: Huawei wins due to its single and three-phase inverters with their own battery (5kWh- 30kWh). However, if you have frequent grid failures, Fronius GEN24Plus has superior backup than other inverters.
  • Perth heat management: Fronius inverters have efficient fans, but many complain that they are noisy. Huawei inverters don’t have fans, but their cooling system works efficiently (internal temperatures don’t go beyond 67°C. Both inverters are great in Perth heat management.
  • Power output: Fronius GEN24+ allows 7.5Kw to 9kW with a battery. However, Huawei 3-phase 5Kw allows 20Kw of panels while single-phase 5Kw inverters allow 10kW of panels. Huawei has more power output. 
  • Shaded panels management: Huawei inverters have an optimiser that manipulates panel voltage to match current with the rest of the string. Fronius don’t have in-built optimisers; hence Huawei wins. 
  • Reporting software: Even without optimisers, Huawei still gives comprehensive reports. Still, Huawei offers a complete reporting package with smart meters and optimisers.

Check Out Our Guides to Solar Inverters

We have a series of unique guides to solar, solar finance, batteries and more, if you are looking to do more in-depth research into solar inverters check the below:

1. What Are Solar Inverters? How Do They Work?
The solar inverter is a very important part of your solar power system: photovoltaic panels generate direct current (DC) when they receive sunlight, but your home appliances run with alternating current (AC) like that from the grid. In simple terms, the solar inverter is the device in charge of converting DC power to AC. 

2. How To Choose A Solar Inverter
There has never been a better time to switch to solar in Australia. Some households can even switch for $0. As the focus grows on solar energy, so does the list of available equipment. The solar inverter is like the heart of a solar system, and there are a number of considerations that go into choosing a suitable solar inverter.

3. Single-Phase vs Three-Phase Inverters: What Are They And Which One Do You Need?
Here is a common rule of thumb to help differentiate between single-phase vs three-phase inverters. Residential homes will usually use a single-phase power supply or inverter, while commercial or industrial facilities will use three-phase supplies.

4. What Do Solar Inverter Error Codes Mean
Solar inverter error codes notify you of a situation threatening the normal operation of your solar power system. Many different things can go wrong and disrupt electricity generation from a solar PV system. The inverter will detect it and generate corresponding error codes to notify you.
