Current power
An instant overview of the power currently supplied by the photovoltaic panels to the water-heating system.
Photovoltaic water heating
Keep track of solar energy and water temperature.
The Monitoring Portal displays the current output of the photovoltaic water-heating system, generated energy and system history. With optional temperature sensors, you can also monitor the current water temperature and how it changes throughout the day.
Everything important in one place
System data is transferred to the portal automatically. You can check the current status and heating history from a computer, tablet or mobile phone.
☀️
Generated energy
An overview of the energy generated today, this week, this month and this year.
📈
Generation history
A power chart shows how generation changed throughout the day and over different periods.
🌡️
Water temperature
An optional Shelly 1 with AddOn module and DS18B20 sensors lets you monitor the water temperature and its development.
▦
Multiple measurements
You can monitor multiple measuring devices or photovoltaic strings under one user account.

Access from anywhere
All you need is a web browser. No separate mobile app needs to be installed.
How the system works
Photovoltaic panels supply DC energy to a heating element installed in the hot-water tank. The measurement and communication unit continuously records power and generated energy and sends the data to the BEL Monitoring Portal.
The system can optionally be extended with a Shelly 1, AddOn and one or more DS18B20 temperature sensors. The portal then shows both the energy obtained from the sun and the water temperature in one place.
