The general trend is the latest 150kW inverter and high-efficiency component matching connection method

Together we move towards higher power

Promote industry development together

On September 13, Huawei released a new industrial and commercial hexagonal warrior product - the industrial and commercial 150kW string inverter (SUN2000-150K-MG0-ZH), which is also compatible with a one-to-two optimizer to form the best industrial and commercial solution, with six major advantages: "more power generation, active safety, long-term reliability, extremely simple operation and maintenance, efficient site construction, and industry-friendly". The product has a rated output power of 150kW and a maximum power of 165kW. It is equipped with 7 MPPTs, each of which supports 3 strings and supports a maximum MPPT current input of 48A.

Not long ago, Growatt also released a new industrial and commercial 150kW string inverter (MAX 150KTL3-X LV). The inverter has 10 MPPTs, and the maximum input current of each MPPT is 45A. Among them, 6 MPPTs can be connected to 2 strings (that is, each string can be connected to 22.5 current), and 4 MPPTs can be connected to 3 strings (that is, each string can be connected to 15A current string).

The two 150kW inverters have different settings, but they have one common feature: they are fully adaptable and compatible with various types of components, especially forming the best match with the recently popular 700W+ high-power components.

According to statistics, as of the first half of this year, the cumulative shipment of 210 modules reached 150GW, and large-size, high-power modules have become the industry's first choice. The 210+N modules launched by Trina Solar have also achieved a breakthrough of 700W+. Modules, inverters, etc. are all moving towards higher power, and the direction is beyond doubt, bringing higher value to the industry chain and terminal market, and promoting the development of the industry. How to configure the new generation of high-power modules and the new generation of inverters has also become a matter of greatest concern to everyone.

Ultra-high power modules and high power inverters

Perfect fit

分布式光伏作为应用场景最为多样化的市场，前景十分广阔，随着技术不断变革创新，高功率组件应用越来越广阔，能够显著地节省光伏电站 BOS成本，有效保障投资方的投资收益率，得到了越来越多的客户的认可。天合光能一直以超高功率组件作为自己的王牌产品，在分布式光伏市场收获了满满的口碑。今年天合主打的210系列DE21-670W组件及NEG21C.20-700W组件也已经受到客户群体的关注。

The following table shows the detailed parameters of the two components.

Table 1 210 series component parameters

Huawei's new 150kW inverter has 7 MPPTs, one MPPT can connect to 3 strings, and the maximum input current of each MPPT can reach 48A. If Trina Solar 210 series modules are used to connect to the inverter, one MPPT can be connected to two strings, and the other input can be left empty:

In March 2022, Trina Solar took the lead in fully disclosing its 210R product solutions and industrial feasibility path to the industry. Based on product design, power maximization, container loading rate and other dimensions, Trina Solar first advocated the standardization of silicon wafer battery module dimensions and innovatively launched the 210R product, which opened the door to rectangular silicon wafer innovation for the entire industry and was unanimously recognized by the industry.

Based on the advanced 210 product technology platform, with the support of this "golden size", the Supreme P-type 585W and N-type 605W series modules have higher string power. Compared with similar 182 products, they greatly reduce the use of photovoltaic cables and bracket rails, shorten the installation time, and reduce the BOS cost of the overall power station. They are worthy of the trust of more and more customers.

Since the optimal operating current of these two components is below 15A, and the maximum input current of each line of Huawei and Growatt 150kW machines can reach 16A, if these two components are used in combination with the new inverter, each input line can be connected to the string. The connection method is as follows:

Guided by technological innovation, Trina Solar is willing to work with inverter companies to promote industry development and technological progress. The new string inverter is equipped with ultra-high power components that are highly favored in the industry. The strong combination has good adaptation and the installation capacity ratio meets industry requirements. It can be said to be the first choice for owners' self-investment and EPC procurement! In the future, Trina Solar is willing to work with partners to bring higher value to customers and the industry!
