Based on years of research, EUPD has developed an annual evaluation model to focus on aspects of successful brand management. The results of the research data collected from installers form the basis of this fully independent evaluation, and more than 10 individual factors were taken into account in the Analysis of the APsystems brand.

“EUPD Research has more than 15 years of experience conducting interviews with installers in the sector. This constant dialogue is unique in the PV market. We are delighted to award APsystems the “Top Brand PV seal” in the category of inverters on the French market. This unique seal is the result of analysis and interviews carried out with more than 100 installers based in France at the end of 2019.” has declared Saif Islam, Senior Consultant at EUPD Research.

The seal is designed to present a complete view of the brand, in which the aspects related to brand awareness and satisfaction are involved as well as its presence in the distribution and its ability to become, for installers, a reference brand in their customer recommendations. The technical properties and characteristics of the brand’s products obviously play a role in this appreciation from solar professionals.  APsystems has built expertise in module-level power electronics (MLPE) for more than 10 years, with over 110 patents on its products and has become the world’s number one manufacturer in the multi-module microinverter segment for solar.

Offering the widest range of microinverter solutions with the YC600 and QS1 in single-phase for residential and the YC1000 in three-phase native for large roofs, APsystems continues to be a leader in photovoltaic innovation serving its clients in more than 80 countries around the world with a team and a local office, close to its French customers, based in Lyon

**FOR IMMEDIATE RELEASE**

ANAHEIM, USA – September 24th, 2018 – APsystems unveils the QS1, a four-module, single phase microinverter for residential applications at the Solar Power International trade show in Anaheim, USA. A new design for APsystems, the QS1 offers 75% faster installation time, while offering the highest peak output power and up to 3X faster data transmission speed than PLC. A wider MPPT voltage range will result in a greater energy harvest for homeowners.

The first of its kind, the QS1 is designed to accommodate today’s high output PV panels up to 375W, offering 300W AC output per channel, the highest among microinverters. The unit also significantly reduces installation time and costs, taking the place of four conventional microinverters per each QS1 installed while still providing four independent MPPT.

The QS1 utilizes a common AC trunk cabling with the dual-module YC600, offering flexible mix-and-match compatibility on the same circuit to enhance site design capability and maximize circuit capacity. Both microinverters also utilize the same gateways; installers can choose from the ECU-R, for single or multi-residential installations, or the ECU-C, for applications requiring consumption monitoring and advanced contact/relay features.

“Compatibility with the existing YC600 microinverter system gives the QS1 an unprecedented advantage,” said APsystems Chief Technology Officer Dr. Yuhao Luo. “Mixing dual and quad microinverters in the same system adds design flexibility while offering a strong inventory and installation labor advantage over conventional microinverters.”

Today’s solar systems require a more robust communication architecture to manage significantly more data points and in-field software updates. A 2.4GHz wireless Zigbee mesh network offers enhanced data transmissions speed, up to three times faster than conventional powerline communication (PLC).

The QS1 builds on the successful APsystems line of multi-module microinverters, offering reduced logistics costs, integrated communication and connection features, and a wider MPPT voltage range for greater energy harvest during low light conditions.

The new microinverter will be on display at the APsystems booth #2838 at Solar Power International, USA.

SUBSOL selects APsystems’ micro-inverter technology for a large scale social housing project supplying solar energy to more than 680 homes in the metropolitan area of Vienne, France.

More than 280 residential and small commercial roofs with an average power of 8 to 9 kWp will be equipped with innovative micro-inverter solutions from APsystems.

  LYON, France – 18 September 2017 – APsystems, the world leader in microinverter technology for the solar industry, today announced that it has been selected by SUBSOL, a design office and developer of roof integrated solar power plants, to be its partner in providing micro-inverter solutions for over 12,000 sqm of solar roofing, an unprecedented project in the metropolitan area of Vienne, Isère, France. A portfolio combining individual and collective multi-residential social housing projects and some small commercial public buildings will be able to provide approximately 2MWh/year, equivalent to the annual consumption of 680 households.

“It is a project put into place by the mayor, financed by local authorities and citizens, and developed above all to bring added value to the territory. SUBSOL is committed to these socially responsible projects and wishes to develop awareness of energy efficiency among tenants.” Said Jean-Baptiste Rouquerol, CEO of SUBSOL.

“We chose APsystems because of its extensive range of micro-inverter solutions, making it possible to easily address single-phase residential projects as well as small commercial buildings with a native 3-phase microinverter solution. The fact of having a local team to support us throughout the project, from the study phase to the ongoing installation phase, has reinforced our decision to work with APsystems.”.

The project is scheduled for completion by July 2018 at a rate of 45 installations per month. Thanks to APsystems’ complete solution that includes 1 micro-inverter for 2 or 4 panels, cables and accessories and an ECU communication gateway used to commission the system, enabling access to online energy monitoring anywhere, anytime via the EMA portal, the installation team, an average of 3 people, is able to complete an 8 or 9kWp installation in only 2 days, ensuring that each site meets its completion date.

“We are delighted to take part in such an avant-garde project. The innovation not only comes from the business model it is based on but also from the social dimension it carries. Solar energy in urban and built-up areas allows room for more innovative, safe and productive solutions, such as APsystems microinverters. We are convinced that this solar operation in Vienne will be a great success, and that it will be a source of inspiration for other cities,” said Olivier Jacques, Executive Vice President, APsystems.
