“The DS3, a completely new architecture”- Interview from Dr LUO, CTO & co-founder of APsystems

 

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. Regarding 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. The DS3, our 3rd generation dual microinverter planned to be released on the market at the end of Q1 2021, not only brings together all the innovations from previous generations but goes even further.


First, it relies on a completely new architecture that will provide 50% higher power, and higher efficiency. We have also added enhanced communication security leveraging Texas Instruments’ Zigbee module, a global benchmark in this field, onto which we are adding a cybersecurity tool called Karamba to make code programming completely inviolable and all PV production data processed by our customers fully secured. In terms of form factor design and microinverter materials utilized for the casing, we have also opted for an innovative, optimized, compact design combining cast aluminum on the front and rugged polymer on the back making the product lighter while maximizing its power. All components are still encapsulated with silicone to reduce stress on the electronic components, facilitate thermal dissipation, enhance waterproof properties and ensure maximum reliability of the system via rigorous testing methods including 20 000 hours of accelerated life testing and many other procedures which are part of our ISO 9001 certification process. This generation is also a result of unprecedented integration work that has enabled us to reduce the number of components by 20% while delivering 50% more AC output power than the YC600, our current generation. It is a technical achievement and an industry 1st to reach a record 900 W AC power output on a dual microinverter! With 97% efficiency and a wide range of MPPT operating voltage, the DS3 will be able to connect two modules up to 650 Wc each. It supports all utility requirements for remote control and programming. It also has improved remote upgrade functions to ensure any future requirements. The product is currently going through all safety certifications and compliances. The DS3 is a groundbreaking, grid interactive product that will democratize even further the use of microinverters in the residential and multi-residential solar market segments.”

Powerful innovations for a sustainable future

World Environment Day  has been celebrated on June 5  to encourage awareness and environmental protection. According to the United Nations, “the celebration of this day provides us with an opportunity to broaden the basis for an enlightened opinion and responsible conduct by individuals, enterprises, and communities in preserving and enhancing the environment.” The day is celebrated by engaging governments, businesses, celebrities and citizens to focus their efforts on a pressing environmental issue and broaden the basis for an enlightened opinion and responsible conduct also for individuals, enterprises and communities in preserving and enhancing the environment.

The theme of World Environment 2020 is ‘celebrating biodiversity’ — a concern that is urgent and existential. The current environmental could be considered of a warning that we must heel collectively or must fundamentally rethink our relationship with the living world, with natural ecosystems and their biodiversity. It is about time to control our lifestyle and contribute to saving the environment by shunning use of plastic, growing trees and using alternative sources of energy. Most of the electricity used by us is generated fossil fuels emits greenhouse gases carbon dioxide (CO2) and nitrous oxide (N2O) causing pollution. These harmful gases also contribute depletion of the ozone layer. Therefore we must turn to solar, wind, or geothermal energy. Installing a solar energy system is an incredibly beneficial financial decision for your home or business, it can also contribute substantially to the wellness of the environment and to public health as a whole.

By using solar, you can reduce demand for fossil fuels, limit greenhouse gas emissions, shrink your carbon footprint or decrease the risk of health issues.  APsystems has given a massive push towards renewable energy generation. All over the world, there are over 100.000 installations with APsystems Microinverters having generated more than 1.2 TW of solar energy by now and resulting in more than 226.000 tons of carbon offset.

Interview from Dr Ling, co-founder and Chairman at APsystems

When uncertain times defy innovation, new opportunities shine brightly for a long time.

This year marks APsystems’ 10th anniversary. While the situation worldwide is facing unexpected challenges on many fronts during this very particular year 2020 with the Coronavirus pandemic, Dr Zhi Min Ling, co-founder and chairman of APsystems, shares his views on his entrepreneurial story with APsystems from its very beginning when the economic effects of the 2008 financial crisis were still strongly present to where APsystems is today, having become the #1 multi-module microinverter supplier in the world. It is as if challenging uncertainty could also be a key in building long-lasting opportunities.

2020 is the year of APsystems celebrating its 1st decade, how does it make you feel?

Fortunate, honored and grateful. It is a major milestone for the company, especially in this very fast-changing inverter industry which is at the crossroads of high-tech microelectronics, energy and environmentally-friendly building sectors. Staying alive is one thing but growing profitably when you need to heavily invest in R&D on one side, while keeping enough agility to adapt to an ever-changing emerging market on the other side, is another challenge. The fact that we have been growing for 10 years while reaching profitability every year since 2012, is primarily down to the hard work, determination and patience of the hundreds of talented and committed people who have joined and believed in this company over the years.

What encouraged you to set up APsystems? And how has the company evolved over the years?

The company has changed dramatically for sure. We can look at the company’s development in two phases, I think. The foundation 2010 – 2012: it was the very beginning where every priority was focused on setting up our expertise in power electronics conversion designs to create a robust and cost-efficient microinverter solution. Within about two years, we managed to design, manufacture and launch our 1st single and duo microinverter products with the YC250 and YC500 which later became the best-selling duo microinverter worldwide. We set up our headquarters in Jiaxing, China, where we still manufacture our products thanks to the help of TDG group, our main shareholder and share our R&D department between Jiaxing and Cupertino….Then the 2nd phase was characterized by one obsession: how to make APsystems Grow Internationally with no compromise to profitability. Although we are still in this phase with constant profitability every year since 2012, I would say that over the past six years (2013-2019), and especially since Olivier Jacques joined the company in 2015, we have managed to structure ourselves by Business Units on all continents enabling us to serve our customers in more than 80 countries today.

What were the main challenges along the way?

It is quite fascinating to be able to be part of this solar revolution. Helping to make solar an affordable clean energy solution to everyone on this earth is inspiring but of course, the technological challenges are big. If you take communications for example, microinverters manage a considerable number of data points that need to be communicated back from the microinverters through the gateway and to the monitoring platform in the cloud. This means when systems like the YC1000, QS1 and YC600 apply remote firmware upgrades, this creates a demanding bidirectional data flow and traditional powerline communication isn’t going to cut it. This is the reason why we moved our portfolio to high-speed wireless Zigbee, which is up to three times faster than conventional powerline communication (PLC), creating a local 2.4GHz mesh network for fast and reliable data communication between the microinverters and the gateway.

Another constant challenge has been to adapt to increasingly complex market needs. The progressive integration of PV into the electricity networks has required Inverter manufacturers in many countries to release products capable of interacting in real-time with grid operators. Whether it is to adjust the PV production instantaneously, depending on the state of the network, or to prevent any electron from being sent back, performing such a functionality for the coming 20 years in a reliable manner with a product smaller than an A4 sheet and weighing 3kg average is a genuine achievement in technological integration, entailing very sophisticated R&D , manufacturing and testing capabilities.

How is the Pandemic situation affecting your activity?

When the COVID-19 first appeared in China at the beginning of the year, our activities were relatively spared since part of our production comes from outside China, even though a slowdown in manufacturing occurred during a period of about 1 month in the first quarter. The good news is that as we master the production infrastructure, we were able to quickly increase our production rate when the situation improved a few weeks later, ensuring a constant continuity of supply to all our customers and warehouse locations across the world.

Despite the inherent agility of our distributor partners and solar installers staying open and continuing their job as far as possible, we have inevitably been confronted by a slowdown in our sales activity worldwide this quarter. Uncertainty is the most difficult parameter to deal with when it lasts, it is the same for everyone as an individual but it is also a genuine opportunity to confront and challenge ourselves by overtaking obstacles with self-confidence. I strongly believe that the creativity and flexibility of our industry will rapidly lead to recovery during the 2nd half of this year.

What’s next for APsystems?

APsystems is now well recognized for its leadership in multi-module microinverters solutions bringing innovative products to market that are built to last. This is the DNA of the company and will continue to be. We have several new microinverter products planned to be launched in the coming 18 months including a new native 3-phase QUAD microinverter at the end of this year, but our ambition moving forward is also to increase our position in other Module Level Power Electronics. We have recently launched, especially in the United States, APsmart, a new Business Unit that includes advanced safety products such as a Module Level Rapid Shut-Down (MLRSD) device to meet new safety regulations on MW-scale solar projects. The APsmart MLRSD System is a SunSpec Alliance Certified device which maintains constant communication between the RSD and Transmitter, constantly monitoring voltage and current. APsmart offers state-of-the-art PV module rapid shutdown devices (RSD), ideal for any new or existing string or central inverter system, and meeting U.S. NEC 2017 690.12 Rapid Shutdown requirements.

APsystems is also working on a modular AC coupled Energy Storage System (ESS) for residential where priority, similarly to every product we manufacture, is given to high quality & reliability.
