How does the control of the eTherm C work ?

Category: Solar energy

The eTherm C relies on external energy management for its operation. The Fronius Ohmpilot or the AC Thor 9S are representatives of the modulating energy managers. This makes it possible to control the eTherm C continuously from 0-9000 W.
In this process, the smart meters of the energy managers measure the excess power at the feed-in point and attempt to regulate the feed-in to zero.
