TBEA Sunoasis’s Inverter System Solution Helps Solar Plant Save Costs and Increase Efficiency

Recently, the “5th Symposium on Design, Engineering and Equipment Selection of New Energy Plant 2020” themed “Closure of the 13th Five-Year Plan and Expectation of the 14th Five-Year Plan”, is held in Guiyang to discuss the industrial development pattern of solar power in the parity age. TBEA Xi’an Electrics Technology Co., Ltd., the wholly-owned company of TBEA Sunoasis and as the industrial leading enterprise of inverter, was invited.

In the solar sub-forum, Zhou Hongwei, the Chief Engineer of TBEA Xi’an Electrics Technology Co., Ltd., delivered a speech on behalf of the company themed “The Innovative Solar Power Solution in the Age of Parity” to share the technical path and solution concerning grid connection of solar power under parity.

As the last year of the “13th Five-Year Plan”, this year is vital for the solar industry to go marketization and into parity, with many measures securing the development of new energy, such as consumption guarantee mechanism, consumption space and market-driven transaction of the power market. Parity project proposes higher requirements for system design, equipment selection, product performance and intelligent operation & maintenance, and the success of a project relies on LCOE-oriented comprehensive evaluation of the entire system. Inverter, as the bridge and bond for solar power system, is an important factor for solar plant to realize optimal electricity costs.

Zhou Hongwei mentioned that, from the current development trend of inverter, the 1,500V system solution, inverter with high power-capacity ratio, large power and intelligent operation & maintenance have become important factors for solar plant to reduce costs and improve efficiency, which is also the primary development direction for domestic and foreign inverter.

TBEA Sunoasis’s TS228KTL-HV Series Inverter, with high DC/AC ratio, high efficiency, intelligent operation & maintenance and high reliability, is just the tool for solar plants. Specifically, it supports large-power dual module, flexible assembly, 24-line input, 12-line MPPT and can effectively reduce the influence of series mismatch; its regular connection supports power-capacity ratio up to 1.3 and such ratio may be improved to 1.6 under Y+1 connection. Its maximum transformation efficiency ≥ 99% and China Efficiency ≥ 98.45%. It has series I-V curve intelligent monitoring and can realize “plant + cloud” dual terminal intelligent operation & maintenance. Protection level of the entire product is IP66 and anti-erosion level C5; it can be adapted to wind sand, salt mist, high temperature and moisture, high altitude and other complex environments.

As one of earliest domestic enterprises engaging in the industry of inverter, TBEA Sunoasis always sticks to the objective of maximizing client value and by reducing electricity costs and introducing technical innovations, helps promote the parity of China’s solar industry on full scale.
