Intersolar Europe
The World’s Leading Exhibition for the Solar Industry

June 18–19, 2024
ICM München
Inter SOlar 2024

Come and meet us at Intersolar Europe.

Exhibiting at EM-Power Europe.

Intersolar Europe is the world’s leading exhibition for the solar industry. It takes place as part of The smarter E Europe – the continent’s largest platform for the energy industry – and focuses on the photovoltaic, solar thermal technology and solar power plant sectors.

Under the motto “Connecting solar business,” manufacturers, suppliers, distributors, service providers, project planners and developers as well as start-ups from around the world meet in Munich every year to discuss the latest developments and trends, explore innovations firsthand and meet potential new customers. Intersolar Europe will take place from June 18 to 19, 2024 at Messe München.

Enterprises in Solar Energy

We provide PV monitoring platforms to installation companies and other professional parties to collect, analyze and store data in a reliable and secure way so that it is always available and remains the property of our customers. No risk that data is no longer available to manufacturers because they stop accessing their portal or make it pay.

Furthermore, our systems are easy to install so that no time is lost due to long training sessions and/or incorrectly connected systems.

We apply First-Time-Right principle which allows the technician to check on site that everything is connected and working properly.


SIMPL IoT energy platform


Consumption and yield data from all connected devices (PV inverters, heat pumps, ventilation, in 1 single platform allowing easy management at a glance.


  • Data is retrieved via an independent and secure readout, so you no longer have to worry about on-site internet/wifi connection.
  • Data is retrieved for all inverter brands or types (micro or string inverter), so no more consulting a separate platform per inverter brand.


  • In addition to PV inverters, devices such as ventilation, household consumption, etc., are also monitored on behalf of Zero-On-the-Meter (NoM) homes and are reported
    according to the EPV regulation.


The platform has several applications, including:

  • PV monitoring
    Monitoring of large-scale PV installations of all brands of inverters
  • Zero-to-the-meter (NoM) monitoring
    Monitoring of inverters, ventilation, heat pumps, meters,f or EPV reporting
  • Home Energy Management System (HEMS)
    Monitoring and control of energy flows to minimize energy consumption and/or costs by optimizing self-consumption, capacity tariff and dynamic tariffs. This involves connected and controllable consumers such as inverter, home battery, charging station and heat pump or thermal storage.
    Analysis-as-a-Service for PV(AaaS-PV)
    With AaaS-PV  we offer professional parties the possibility to provide PV generation data to check which installations are working well or are not.
