Inverter solare ei-uno
Single-phase hybrid inverter with ON-GRID connection
The ei-uno hybrid inverter is the single-phase model for ON-GRID connection, specifically designed for residential applications, capable of managing up to 17.3kW with energy production and consumption monitoring via App and Beghelli cloud thanks to the integrated Wi-Fi module. Alternating current output for use of the energy supply in the event of a grid blackout.
