What is the Huawei Sun2000 KTL L1 Inverter?
The Sun2000 is a single-phase grid-tied inverter with a PV string that helps convert solar energy from DC power to AC power. The electricity generated will then feed into the power grid for household appliance use.
This Huawei inverter has a separate model exclusive to Australia. The model names provide information about the specific product, such as its size (power level), product family name, topology, and design code.
Consider this model identifier:
- One = This is the product family name. In this case, Sun2000 is a grid-tied solar inverter.
- Two = This is the power level. The number with “K” indicates the power level of the product. For example, if the product you buy is Sun2000 5KTL L1, it will have an output voltage of 5 kW.
- Three = This represents the topology of the inverter. The letter “TL” shows that it is a transformerless inverter.
- Four = This refers to the product’s design code. Here, “L1” is “residential”. It means that the Sun2000 KTL L1 Inverter is designed for residential purposes.
The Sun2000 KTL L1 inverter, designed for residential use, applies to household rooftop grid-tied systems. This system is composed of PV strings, grid-tied solar inverters, AC switches, and power distribution units. Such distribution units are used to control electrical power in a data centre.
Even though Huawei Technologies Co. Ltd is a relative newcomer in the solar industry, it has quickly risen to one of the leading positions in the market by manufacturing some of the best solar inverter products.
Huawei consistently led the global solar inverters market as the largest inverter supplier from 2015 to 2019. Wood Mackenzie presented estimates of the global market share in 2019, which showed Huawei at the head of the pack once again.
Huawei’s manufacturers are known for using state-of-the-art technology for building the inverter systems. And despite Huawei’s main facility being located in the distinctly Chinese city of Shenzhen, the manufacturing process of the company’s inverter systems is more global than you might think.
Developers design the chipsets used in this system in Silicon Valley, California. The architecture and configuration of the inverters are derived from the company’s German brand, located in Nuremberg, Germany. The inverter technology of this system is then brought from Huawei’s company branch in Sweden.
Huawei Sun2000 KTL L1 Inverter Range
The Huawei Sun2000 KTL L1 inverter has specific efficiency and power output levels based on the model. It can range from 2,000 watts to 6,000 watts with a voltage range of 90 volts to 560 volts.
The product model range includes:
- Huawei Sun2000 2KTL L1
- Huawei Sun2000 3KTL L1
- Huawei Sun2000 3.68KTL L1
- Huawei Sun2000 4KTL L1
- Huawei Sun2000 4.6KTL L1

Take note that inverter costs can add up to 10% to 20% of your expense on your entire solar power system. Thus, investing in the highest quality inverter you can will significantly influence the efficiency and performance of your solar power project.
Fortunately, the Australian government sees the benefits of installing solar panels for commercial and residential purposes. In fact, they have a law and specific regulations for both large-scale and small-scale regulations.
The government provides incentives to encourage more solar installations in the country. However, the incentives may vary by state and have specific requirements to meet their eligibility.
With its heavy regulated and scrutinised solar industry, it’s no wonder that South Australia achieved a global milestone. The jurisdiction is the first globally that’s powered solely by solar energy.
