tubra®-eTherm P
Power to heat
The station for storing surplus electrical energy as heat in the buffer or hot water tank
- Stepless power modulation in accordance with VDI guidelines
and EMC-compliant => CE mark - Charging the storage tank for high storage capacities
through target temperature control - a system controller for current measurement, power control and storage charge management
- independent of PV components, completely pre-assembled
Power extension
eTherm
optional functions:
- reheat function
- additional consumers – up to 12 kW stepless modulation
- inverter power limitation
- remote control Smart Remote
- adjustable reserve power for peak shaving of PV peaks
- combination with heat pumps – Smart Remote ready
- combination with batteries – maximum PV self-consumption
- cascading of one eTherm P and one eTherm C possible
Power extension
