Interview with Dr. Yuhao LUO. APsystems co-founder and CTO, based in Cupertino, Silicon Valley, unveils the technological background of the most powerful microinverter on the market: the NEW dual DS3 (for Dual, Single- phase, 3rd generation) coming in Q1 2021.
Dr. Luo, APsystems is planning to launch its 3rd generation dual Microinverter very soon, how does this product differ from previous generations?
« It has now been a decade since we gradually established ourselves as the global benchmark in multi-module microinverters for the solar industry. Our expertise in power electronics allows us to design and manufacture a wide range of MLPE solutions (Module-Level Power Electronics) on top of our well-known range of microinverters. Regar- ding our dual microinverter range, the 1st generation with the YC500, launched eight years ago, has received a phenomenal reception in the world market and has strongly reinforced our idea that a dual microinverter architecture solution with 2 MPPT connecting two modules makes complete sense.
Since then, we have not stopped innovating, year after year, with ever more powerful, integrated and intelligent products. In 2017, we launched the 2nd generation of single-phase dual, the YC600, which, beyond superior AC output power, incorporates Zigbee communications with all the competitive advantages it brings in terms of signal speed, robustness and ease of installation for professionals. The company has also chosen to integrate this communication technology across the entire product range. At this stage, we also needed to make our products interactive with power grids. A feature commonly referred to as RPC (Reactive Power Control) or reactive power factor management, has been increasingly requested by utilities to better manage photovoltaic power spikes in the grid and facilitate its integration. This is a requirement, already in force in countries like Germany, US, Italy or Australia, which is gradually spreading all over the world.
