New product launch | TBEA grandly launches a new generation of string inverters

After more than a decade of rapid development, the photovoltaic industry has become an important part of my country's energy. Various innovative technologies are changing with each passing day, pushing the photovoltaic industry towards "grid parity". On April 13, 2018, at the "2018 (Xi'an) Photovoltaic Parity Innovation Solution Seminar" held by TBEA and the China Renewable Energy Society in Xi'an, TBEA's new generation of string inverters was grandly released, with an MPPT penetration rate of 100%, which comprehensively improves the power generation of photovoltaic power stations.

Smart photovoltaics lead the way, and affordable photovoltaics are just around the corner

The photovoltaic "leader" has become the vane of the photovoltaic industry. In particular, from the analysis of the recent third batch of leaders' winning bids, the proportion of complex terrain and bifacial components in power stations is increasing. Inverters are the core equipment for increasing the power generation of photovoltaic power stations. Only through continuous technological innovation, adapting to local conditions, and maximizing the potential of photovoltaic power stations, can we lead the reduction of system costs and the increase of power generation, thereby reducing the cost per kilowatt-hour, getting rid of subsidies, and achieving grid parity.

TS80KTL_PLUS string inverter "empowers" high-efficiency components, increasing power generation by 4%+ in complex terrain conditions

In complex terrain conditions, photovoltaic power stations may suffer from string-parallel mismatch losses due to string voltage, installation inclination, installation orientation, and shadowing, which will greatly affect the power generation efficiency of the power station. The best solution to the string-parallel mismatch problem requires a breakthrough in inverter MPPT penetration technology. Currently, the highest MPPT penetration rate of string inverters in the mainstream market is only 50%.

TBEA TS80KTL_PLUS string inverter has 12-way DC input and 12-way MPPT tracking features compared to traditional string inverters. Independent MPPT tracking technology increases the string MPPT penetration rate to 100%. When used in complex terrain, it can increase system power generation by at least 4%+ and reduce parallel mismatch loss to 0. At the same time, the independent MPPT design enables the inverter to have natural anti-reverse connection, ensuring system safety and stability.

Reliability and efficiency are the goals pursued by our TBEA products.

In addition to the 100% peak MPPT penetration rate, the TS80KTL_PLUS string inverter also has the highest conversion efficiency in the industry, with a maximum conversion efficiency of 99.23% and a Chinese efficiency of 98.63%. At the same time, the product adopts an independent MPPT design, and no fuse is required on the DC side. Each MPPT has an independent boost circuit, which ensures that it has a natural anti-reverse connection function, making it safer and more reliable.

TS75KTL_BF group string inverter "partner" bifacial module assembly, 30% output overload capacity

Bifacial modules are increasingly widely used in the photovoltaic power generation base. Bifacial modules are favored by the industry and the investment community for their super-strong power gain on the back side. For bifacial cells, the current inverter overload capacity in the industry is only 1.1 times, which cannot "match" the demand for bifacial high-efficiency modules. This power reduction phenomenon is bound to occur, resulting in power generation loss. As the bridge and link of the photovoltaic power generation system, how can the inverter better exert the "performance" of the module and make the inverter and bifacial modules a perfect match?

With 18 years of technical accumulation in the development of photovoltaic inverter products and system solution design, TBEA has launched the best partner for high-efficiency bifacial modules - TS75KTL_BF string inverter. This product also has 12 independent strings and a peak characteristic of up to 100% MPPT penetration, which completely solves the string-parallel mismatch loss. At the same time, this product is designed to perfectly match the dynamic overload regulation capability of bifacial modules. In particular, when the ambient temperature is below 0°C, it meets the 1.3 times long-term output overload capacity, and when the ambient temperature is within 45°C, it meets the 1.2 times long-term overload capacity, which is tailor-made for bifacial modules.

Wisdom changes photovoltaics, technology brings change

The new generation of string inverters launched at this new product launch conference is an innovative achievement of TBEA in the field of photovoltaic grid-connected technology. The series of products have a 100% MPPT penetration rate, which completely solves the mismatch loss of string and parallel connection; the fuse-free design is naturally anti-reverse connection, which is safer and more reliable; the output overload capacity of 20%+, and the perfect match with high-efficiency components, etc., have once again injected "innovation" vitality into the photovoltaic market, strongly promoted the development of the photovoltaic market, and better explained TBEA's pursuit of maximizing customer value.
