Charge level of internal energy storage
More energy is generated than
consumed. The excess energy charges
the internal storage
The excess energy stored during winter time is used
to power the system through the warmer months.
The system works continuously throughout the year.

Energy Harvesting
with Thermogenerator
Thermoelectric principle
• Thermogenerator converts temperature difference
between radiator intake and ambient air into electricity.
• Energy Harvesting enables battery-free, maintenance-free
and wireless operation by using radiator heat.
• Perfect for wireless sensor and actuator equipment
for building automation applications.
