Hybrid inverters

ei-tre

The ei-tre hybrid inverter is a three-phase model, which was specially developed for the service sector and small industrial applications and is capable of administrating up to 23 kW. An application in the living area is also possible. Energy generation and the consumption are monitored over an app and the Beghelli cloud. AC output for use of the energy reserve in case of power failure.
