The 17th China (Jinan) International Solar Energy Utilization Conference in 2022 and China (Shandong) International New Energy Industry Expo was held at Jinan international convention & exhibition center from July 23rd to 25th. With the characteristics of "effectiveness, professionalism, innovation and authority" and brand image, the conference has attracted the participation of many domestic and overseas industry insiders, and has become a national event with high specifications, great influence and many exhibiting enterprises in the industry.

Accumulating Steadily to Make a Brilliant Appearance

The exhibition has been delayed for a long time due to the pandemic. Enterprises and the audience have been expecting it for a long time, so the exhibition has attracted more and more attention. At the exhibition site, Shandong Aotai booth was crowded with new and old customers who came for business negotiations. Of course, products presented at Aotai booth enjoy many advantages this time. All products of industry and commerce, residential and energy storage series made an impressive appearance, which shows the achievements of the latest and cutting-edge R & D and design of Shandong Aotai in an all-round way. All series of products enjoyed great reputation in the audience.

Innovate With the Strength

The continuous innovation of products R&D pushes forward the green development of intelligent energy.

ASP-110/136KTLC

The smart inverter specially designed for industry and commerce, and large-scale distributed solar power station

It integrates 10 MPPTs to be adapted to complex application scenarios. It is the transformerless isolated inverter with a maximum efficiency of 99.01% and a maximum current per string of 15A, which matches two-sided PV modules perfectly. It can perform 1.1 times overload operation long-termly at 45℃ and full-load operation at 50℃. It also equips the night PID repair function to extend modules’ service life and ensure power generation capacity. The whole machine enjoys stronger environment adaptive capacity because of its IP65 class protection.

The aluminum cable can be adopted as the AC input cable to save AC cable costs. It also equips PLC communication to save communication cable costs. In addition, it enjoys flexible design for especially convenient maintenance, capacity expansion, or modification in the later period.   

Meanwhile, it equips several technologies, including online health examination, active and passive anti-island detection technology, I-V scan function, night SVG function, real-time fault alarm, and active warning of an abnormal power station, so as to obtain the highly efficient operation of power station equipment in the complex operating environment and realize precise, high-efficiency, active and worry-free O&M. All series of single-phase and three-phase smart string inverters and intelligent energy storage inverters of Shandong Aotai can be applied to meet all requirements of all photovoltaic application scenarios. 

ASP-15/28KTLC

The key product for rental market of residential distributed PV system

It integrates 2 MPPTs, which can adapt to the installation features of complex residential orientation and the great difference in the number of string panels. It enjoys 1.5 times excessive distributing capability for DC input power and 1.1 times AC overload capability. It also enjoys a higher power generation capacity because of its maximum conversion efficiency of 98.8%. The voltage is improved to 1100V. And the inverter is fully compatible with high-efficiency and two-faced solar modules. Then, the system design is optimized and improves benefits.

The algorithm is further optimized, the weak grid supporting capability is strong, and the grid-connected performance is more stable. It adopts tri-level SVPWM control technology; It equips IP66 class protection, the top-level AC and DC secondary lightning protection and many other safety detections and protections. The digital DSP control technology is equipped to provide intelligent monitoring and flexible O&M and realize intelligent home energy management.
