Intersolution: trade fair for solar energy in Belgium, January 15th and 16th in Ghent

Meet Rexel and APsystems during Intersolution

On Wednesday 15th  and Thursday 16th of January 2020, the 9th edition of InterSolution, the network and trade fair for solar energy in the Benelux, will take place in Flanders Expo Ghent,

The attention and demand for solar energy increases enormously every year, not only do companies invest more and more in solar solutions, but also residential house owners. Solar energy is and remains the future. In previous editions where an average of 3,800 visitors were registered – an international B2B forum is organized for the solar industry during InterSolution 2020, where supply and demand meet.

Leading suppliers from Europe demonstrate their latest novelties, latest products in the field of solar panels and energy storage, mounting systems and control technologies, software and monitoring. A visit to InterSolution is instructive for every professional who comes into contact with the solar business, such as installers, electricians, contractors, roofers, plumbers, architects, housing corporations and associations. Together with Rexel, APsystems shows not only practical but also the latest solutions at Intersolution.

The collaboration between Rexel Belgium and APsystems contributes to more smart solutions for a sustainable world.

APsystems also supports Rexel in sales, support, training and marketing. Like other official APsystems distributors, Rexel offers installers the right knowledge of APsystems products for the best possible experience.

Come and meet both APsystems  & Rexel teams on booth 8103, 15th and 16th of January in Ghent.


APsystems EMA Monitoring web portal and ECU app Now available in Spanish

The Energy Monitoring Analysis (EMA) and ECU APP are  available in spanish !

APsystems is proud to launch a Spanish language option for its Energy Monitoring & Analysis (EMA) web portal to enhance service to its Spanish-speaking customers around the world. Users can view their solar array performance using the same URL and log-in information as before at

APsystems now offers 5 language options for its EMA portal for regional markets including English, Chinese, French, Portuguese and Spanish. The web-based platform, available for free on any connected device, monitors and reports module-level energy production of solar arrays. It also enables APsystems-registered solar installers and contractors to create and manage their customer’s energy monitoring accounts.

Spanish-speaking APsystems customers to help them better manage their solar systems.

the ECU APP is also available in spanish ! This smartphone application is designed for solar professionals only, to ease the commissioning process. Installers use the app to register microinverters into the ECU-R and to connect the ECU-R to the local internet.

The APsystems Energy Communication Unit-Residential (ECU-R) is the information gateway to and from APsystems solar microinverters. The unit collects module performance data from each microinverter unit and transfers this information to an online database in real time, requiring only an Internet connection (via wired CAT5 or Wi-Fi) and power cable. Through the APsystems Energy Monitoring and Analysis (EMA) cloud-based service, the ECU-R gives the homeowner precise analysis of each microinverter and module in their solar installation.

  • See the status and configuration of the ECU-R gateway and monitor each inverter
  • Display real-time energy production and other performance data
  • Connect ECU-R to the router to upload data to the server and control the ECU-R gateway
  • Obtain an IP address automatically or use a static IP address
  • Reset inverter IDs in the ECU-R
  • Reset the ECU-R to display current time
  • Reset the WIFI password



Upgraded QS1 Microinverter with ZigBee functionality : a genuine game-changer !

APsystems recently expanded the QS1 microinverter with an integrated antenna. The QS1 is a micro-inverter that can connect up to 4 solar panels. Designed for high performance panels with 4 independent MPPTs, the QS1 is the ideal choice when 4 solar panel are connected to one microinverter. Thanks to the integrated antenna, installation is now even faster and easier. With this, the QS1 also has standard Zigbee functionality built in.

Zigbee functionality

APsystems microinverters are communicating via Zigbee communication protocol, which ensures (just like for example Wifi and Bluetooth) that they are in contact with each other and can always communicate. Zigbee is a “mesh” network which means that every device with this functionality is connected by using sensors.

Because the devices are mutually connected, the range is increased and they can take over each other’s communication function. They create their own network of communication. This way communication can still take place in the event of a device failure. If an inverter does not connect or fails due to unpredictable reason, contact can still be made from another (Zigbee) device. In a mesh network, everything works together at a distance of 10 to 20 meters, whereby the range depends on signal strength, interference or interference with the signal, such as through walls or electricity. The Zigbee protocol uses the same encryption as banks, 128 bit symmetrical, and is secure.

Maximum power: MPPT

The power that a solar panel can deliver will change every hour of the day due to the light intensity, shade, but also due to the temperature. The MPPT functionality (Maximum Power Point Tracker), will allow the solar panel to perform optimally (and not maximally) and look for the greatest possible power. The inverter will determine the output voltage of the solar panel to achieve the best and correct power output. The MPPT is therefore not a fixed value due to variation in weather, light intensity and temperature. A solar panel will generally not deliver the maximum when the sun shines strongly. APsystems microinverters ensure maximum yield per solar panel. Each solar panel connected to a micro-inverter has separate MPPT (Maximum Peak Power Tracking) control, which supplies the maximum amount of power to the electricity grid, regardless of the performance of the other panels in the setup.

Module-level monitoring

The QS1 micro-inverter in combination with an ECU-R or ECU-C  gateway and the APsystems EMA application (Energy Monitoring and Analysis software) offers you extensive monitoring of your solar panel system through a user-friendly application. The software analyzes and reports the performance of every panel in your solar system. You can view this data using your computer, tablet or mobile. In contrast to many conventional “string” systems, the APsystems EMA offers you control of every individual solar panel and micro-inverter in your solar system and optimization of performance over the lifetime.

The APsystems ECU gateway continuously detects the micro-inverters and solar panels that cause any malfunctions and are connected to your solar panel system. The ECU can also be used to reconfigure and remotely diagnose your system. The web server integrated into the APsystems ECU offers you a clear overview of the performance of your PV system in a few seconds.

Ask your distributor about the possibilities and availability of the QS1 microinverter.

Thank you for visiting us at a great European Intersolar edition 2019 !

The APsystems team was pleased to introduce you to the company’s already well-known power electronics expertise through its new line of compatible multi-module microinverter solutions including the YC600 and QS1.
